Choosing metal screw caps for glass bottles starts with one detail: the bottle’s neck finish. A cap’s diameter alone does not guarantee a fit, and liner material matters if you plan to store liquids or use hot-fill methods. The options below range from general-purpose aluminum lids to caps made for a specific 28-400 thread, so check your bottle measurements before ordering.

INCREWAY 28mm Aluminum Caps: A Versatile Replacement Pack
INCREWAY’s set includes 40 aluminum caps with a stated inner diameter of 2.8 cm. The lightweight metal construction and textured outer rim are intended to make the caps easy to grip and twist. They are described for use with glass bottles and other storage containers, including homemade beverages and pantry items.
This is a practical option when you need a batch of replacement lids and have already confirmed that your bottle’s opening and thread match. The product information does not specify a neck-finish code or describe a liner, however. That makes it less certain than a cap sold for a clearly named finish, especially if you need a dependable liquid seal.
Pros:
- 40 caps in one pack for regular replacement needs
- Lightweight aluminum body with a textured grip
- Stated 28mm inner diameter makes initial size screening easier
Cons:
- No specific neck-finish code is provided
- No liner is listed, so sealing performance may depend on the bottle and use
Verdict: Choose INCREWAY for a larger supply of basic aluminum caps if you can verify the bottle’s thread and do not need a specified liner.
North Mountain Supply 28mm Caps: The Clearest Thread Specification
These black metal caps are sold as a 15-pack for compatible North Mountain Supply containers with a 28-400 continuous-thread finish. Each cap has a plastisol liner, and the product description identifies it for hot-fill applications. Of the products here, this one gives the most specific guidance about the finish required.
That clear fit requirement is also an important limitation: “28mm” by itself is not enough to establish compatibility. The listing cautions that these are not universal 28mm replacements and excludes growlers and standard screw-top wine bottles. Check the bottle or container finish before buying rather than relying on diameter alone.
Pros:
- Specifies a 28-400 continuous-thread finish
- Includes a plastisol liner
- Product information identifies the liner for hot-fill applications
- Made in the USA, according to the listing
Cons:
- Not a universal 28mm cap
- Not intended for growlers or standard screw-top wine bottles
Verdict: This is the best-defined choice for a compatible 28-400 bottle or container, but it is not a safe pick unless that finish matches yours.
VINTORKY 50-Pack: A Compact Option for Small Containers
VINTORKY provides 50 aluminum screw caps for bottles, jars, and other containers. Each cap is listed at 0.70 inches wide and 0.51 inches high, making this a compact option compared with the wider lids in this roundup. The description says the threaded closure is designed to help reduce leaks during storage or transport.
The large pack may be useful for a small business, craft area, or household that needs several replacements. But the listing does not name a neck finish or specify an inner liner. Its general fit claims should not replace a measurement check, particularly if you intend to carry liquids or store a bottle on its side.
Pros:
- 50 caps per pack
- Compact size for smaller containers
- Aluminum construction
- Described for bottles, jars, and spice containers
Cons:
- No neck-finish code is provided
- No liner details are listed
Verdict: Consider VINTORKY if you need many compact caps and can confirm that their size and thread match your containers.
GRADENEVE 53mm Lids: A Wide-Mouth Choice With Fit Questions
GRADENEVE’s aluminum lids are described as 53mm wide and intended for compatible wide-mouth juice bottles, jars, and cups. Their larger size sets them apart from the smaller caps in this list. The product description also says they can be rinsed and reused.
There is a notable fit ambiguity in the supplied product details: the title and measurements point to a 53mm lid, while part of the description also calls them 28mm caps. The listing is marked unavailable in the product information supplied for this article, and exact compatibility is unclear. Confirm the size and neck finish on the listing and your container before considering this option.
Pros:
- Wide 53mm size may suit compatible wide-mouth containers
- Aluminum construction
- Described for jars, cups, and juice bottles
Cons:
- Product details give conflicting size information
- Availability is marked as unavailable in the supplied product data
Verdict: Treat GRADENEVE as a possible wide-mouth replacement only after confirming the actual size, fit, and listing availability.
OLYCRAFT Silver Caps: A Lined Option With a Compatibility Caveat
OLYCRAFT’s 36 silver caps are described as aluminum closures with a liner intended to help limit leakage and protect contents from air. The product description lists a 30mm outer diameter and says the caps suit round steel tins with a 27mm inner diameter. Although the title mentions glass bottles and beer, the stated fit detail focuses on tins.
There is also a liner-material difference within the product information: the title mentions plastisol, while the description calls the liner PE. If liner type matters for your contents or filling process, confirm the material with the seller before ordering. The listed dimensions and opening type should be checked against your bottle rather than assumed to fit a standard neck.
Pros:
- 36 caps in the pack
- Aluminum construction with a liner described in the product details
- Column-shaped design is intended to be easy to grip and twist
Cons:
- Stated fit is for round steel tins, not a named glass-bottle finish
- Product information conflicts on the liner material
Verdict: OLYCRAFT may work for the specified tin opening, but verify both the fit and liner material before using it on a glass bottle.
How to Choose Metal Screw Caps for Glass Bottles
Match the Neck Finish, Not Just the Diameter
Start by checking the bottle’s neck finish, which describes the opening’s diameter and thread style. A cap marked 28mm may not fit every 28mm bottle. When possible, look for a finish code such as 28-400 and match it to the bottle or its original closure. If the cap listing does not give a finish code, contact the seller or compare the cap’s measurements with the bottle before ordering.
Check the Opening and Cap Measurements
Compare the cap’s inner diameter with the bottle opening, and make sure the thread spacing and depth are compatible too. A cap that looks close in size may still fail to engage the threads or sit evenly. Be especially careful with products that use broad terms such as “universal” or list conflicting measurements.
Choose a Liner That Fits the Job
A liner sits inside the cap and can help form a seal against the container’s rim. Some options in this guide identify a plastisol liner or a PE liner, while others do not list one. If you need to store liquids, reduce leakage, or use a hot-fill process, confirm that the liner is included and suitable for that use. Do not assume that every metal cap has a liner or is appropriate for hot filling.
Consider What You Will Store
Dry pantry goods, craft supplies, and liquids can have different sealing needs. A basic threaded cap may be enough for some storage tasks, while liquid storage or transport calls for a carefully matched closure and liner. Follow the product’s intended use and test a newly fitted cap with a small amount of liquid before relying on it for transport.
Pick a Pack Size That Makes Sense
Pack sizes here range from a smaller set to larger batches. A small pack can limit leftovers while you check fit; a larger pack may be more convenient once you know the cap matches your bottles. Do not let a high cap count outweigh an uncertain thread fit.
Review Conflicting or Missing Product Details
Some listings provide a specific finish, while others give only a diameter or contain inconsistent measurements. Check the latest product details and compare them with your bottle before buying. If a liner material or compatibility detail is important, ask for clarification rather than guessing.
Frequently Asked Questions
Will any 28mm screw cap fit a 28mm glass bottle?
No. The diameter is only one part of the fit. Thread style and neck finish also matter. For example, the North Mountain Supply caps are specified for a 28-400 finish and are not described as universal replacements.
What does 28-400 mean?
It is a neck-finish designation that identifies dimensions and thread details for a container opening. Match the full finish designation when possible instead of relying on “28mm” alone.
Do metal screw caps always have liners?
No. Some products list a liner, such as the North Mountain Supply caps, while other listings do not specify one. Check the product details if you need a lined closure.
Can I use these caps for hot-fill bottling?
Only use a cap for hot-fill applications when the product information identifies it as suitable. The North Mountain Supply listing specifies a plastisol liner for hot-fill applications. Do not assume that the other caps have the same use.
Are aluminum caps suitable for storing liquids?
They may be suitable if the cap matches the bottle and provides an appropriate seal. Confirm the neck finish and liner details, then test the closure before storing or transporting valuable contents.
Which option is best for a 28-400 container?
The North Mountain Supply caps are the clearest match in this list because the product information specifies a 28-400 continuous-thread finish. They are intended for compatible containers, not every 28mm bottle.
What should I do if the cap measurements are unclear?
Compare the cap with the original closure or bottle specifications, and ask the seller to confirm the neck finish and liner details. Avoid ordering based only on a photo or a general diameter claim.
Final Recommendation
For a bottle with a confirmed 28-400 finish, the North Mountain Supply caps are the most clearly specified choice in this group, with a listed plastisol liner. If you need a larger batch of general aluminum replacements, INCREWAY is worth considering once you have confirmed the fit. For every option, match the full neck finish and check liner details before using the cap for liquid storage.
