Best for Colorful Fabric Bags – ilauke 400-Set Snap Buttons Kit
The ilauke kit stands out among snap fastener kits for bags with 400 plastic snaps in 20 colors and a reusable snap plier. It is aimed at fabric projects, including fabric bags, clothing, pet items, and other medium- to heavy-weight materials.

Cons:

- Not recommended for ultra-thin, highly elastic, or heavy fabrics.
- The included T5 snaps are 12 mm, rather than the 12.5 mm size of the metal kits.
This kit is a strong value for high-volume fabric work and color coordination. It is less suitable for leather or heavy-duty bag hardware because the snaps are plastic and the plier has specific fabric limitations.

Among snap fastener kits for bags, this Hapden option stands out for its plier-style installation tool and included canvas snaps. The adjustable design is intended to provide leverage while repairing or replacing snaps on fabric, leather, tarps, and other materials up to 3 mm thick.
Best For: Bag, canvas, tarp, and outdoor-fabric repairs where a handheld crimping tool is more convenient than a hammer-style setter.
Pros:
- Includes a punching die, helping handle both punching and snap installation with one tool.
- Vice-grip system and adjustable design provide added leverage during crimping.
- Comes with 100 snap sets in silver, black, bronze, and gold.
- Phosphated galvanized body and heat-treated dies are designed for durability.
Cons:
- Snaps are specified for materials up to 3 mm thick.

Choose this kit if quantity and color selection are priorities. It offers broad project coverage, but the fabric-thickness limitation means lightweight bag materials may require a different fastener solution.
Heavy-Duty Versatility Pick – Rivets and Snap Press Kit
For heavier bag materials and multi-purpose repairs, this kit combines 160 double-cap rivet sets with 40 sets of 15 mm snap fasteners. Its forged-steel press pliers use interchangeable dies and include an integrated punch, making it a substantial option among snap fastener kits for bags and leathercraft.
Best For: Thick leather, canvas bags, tool pouches, upholstery, and projects that also need rivets.
Pros:
- Includes 40 sets of 15 mm snaps in gold, silver, copper, and black.
- Also provides 160 double-cap rivet sets in two post heights and four colors.
- Heavy-duty press pliers combine snap and rivet dies.
- Integrated punch and lever design are intended to reduce installation effort.

This is the strongest fit for shoppers who need one press tool for both snaps and rivets. Its larger components and heavy-duty focus make it more appropriate for durable bags, leatherwork, canvas, and repair tasks than delicate fabrics.
How We Picked the Best Snap Fastener Kits for Bags
We focused on the features that matter during real bag repairs and sewing projects: snap diameter, hardware quantity, tool quality, included hammer or pliers, material compatibility, and ease of installation. The selection includes compact beginner kits, colorful multi-pack assortments, heavy-duty canvas and boat-cover sets, and leather-focused options.
Because snap systems are not universally interchangeable, we also considered whether each kit provides a complete matching set of caps, sockets, studs, and posts. A kit with more pieces is not necessarily better if its setter does not match the hardware.
Quick Comparison
| Best For | Look For | Typical Kit Style |
|---|---|---|
| Clothing, pouches, and lightweight bags | 12–12.5 mm snaps and a basic setter | Compact hammer-and-punch kit |
| Leather bags and structured crafts | 15 mm hardware, sturdy tools, and accurate dies | Leather snap or rivet kit |
| Canvas, totes, and outdoor covers | Heavy-duty metal snaps and a punching-capable tool | Large snap setter kit |
| Frequent repairs or multiple projects | High piece count and replacement colors | Bulk assortment or pliers set |
Key Buying Factors for Snap Fastener Kits for Bags
Snap Size and Material
Measure an existing fastener before ordering. The 12 mm to 12.5 mm range is common for lightweight bags, pouches, and garments, while 15 mm snaps can provide a more substantial look and stronger closure. Brass, stainless, or plated metal may be preferable to thin hardware when the bag will see frequent use.
Installation Method
Hammer-and-punch kits are inexpensive and portable, but they require a firm, flat work surface and careful alignment. Pliers are convenient for lighter materials and repeated installations. Heavy-duty setters are better suited to thick leather, canvas, and layered bag panels, provided the included die fits the snap style.
Fabric Thickness and Reinforcement
Snaps work best when installed through properly supported material. Thin fabric may need interfacing, a reinforcement patch, or a small leather tab. For thick leather and canvas, confirm that the post length can pass through all layers without leaving the snap loose.
Quantity and Color Selection
Bulk kits reduce the cost per snap and make sense for makers, while smaller sets are less wasteful for one repair. Multiple colors can help match hardware to different bags, but a smaller set of consistently finished metal snaps may be preferable for a polished project.
Who Should Buy Which Snap Fastener Kits for Bags?
- Beginners: Choose a complete 12 mm or 12.5 mm set with a punch, setter, hammer, and straightforward hardware assortment.
- Leather crafters: Look for 15 mm snaps or a combined rivet-and-snap kit with sturdy pliers or heavy-duty setting tools.
- Canvas and outdoor repair users: Prioritize heavy-duty snap tools, longer posts, and hardware designed for thick fabric or covers.
- Frequent DIY makers: Select a higher-count kit or pliers-based system with several colors and enough replacement pieces for future projects.
Before installation, test one snap on scrap material of the same thickness. This confirms the post length, prevents wasted hardware, and helps you adjust the setting force before working on the finished bag.
