Caydo Snap Fastener Kit 400Set for Thin Leather & Denim — Multi-Size Metal Fastenings with 7 Tools

Caydo 400Set is a complete snap fastener and fitting kit with rivets, grommets, buttons, screws and seven fixing tools designed for thin leather, denim and fabric repairs or DIY projects.

This all-in-one pack combines a wide variety of metal fittings and the small tools you need to attach them, so you can fix or customize jackets, jeans, bags, belts and lightweight leather goods without hunting for individual pieces. The components are plated copper-zinc alloy for corrosion resistance and come in multiple colours and sizes suited to common repairs and decorative projects. With clear sizing options and both short and long posts included, the kit works well on thin leather, canvas and layered fabrics.

What parts are included and what sizes will I get?

The Caydo 400Set groups fasteners and accessories into practical counts so you have extras for multiple projects. Rivets, eyelets, grommets, cap-buttons and two post-length screws cover the most common sizing needs for thin leather and denim applications.

• About 200 leather rivet sets in two sizes: 6 × 6 mm and 8 × 8 mm.
• Approximately 140 eyelets and grommets; internal grommet diameter ~6 mm (1/4 inch).
• Around 40 cap-button sets; cap diameter ≈ 12.5 mm (0.49 inch).
• 20 screw-post sets with two post lengths: ~6 mm and ~8 mm, plus 7 fixing tools.

How do the materials and finish affect longevity?

The fittings are made from a copper-zinc alloy with a plated finish that resists tarnish and keeps parts looking fresh after repeated wear. While no metal is impervious, the plating slows corrosion and helps the fasteners maintain a consistent appearance on garments and accessories.

• Copper-zinc base for good strength and malleability during installation.
• Plated surface resists discoloration and extends usable life.
• Suitable for items exposed to normal wear rather than heavy industrial stress.

Which fabrics and projects are best suited for this kit?

This kit is optimised for thin leather, canvas, denim and similar fabrics where small, neat fasteners are required. It’s ideal for visible repairs, decorative accents and light structural attachments such as straps or tabs on bags and clothing.

• Leathercraft: bracelets, thin belts, small bags and jacket trims.
• Clothing repair: jeans fly snaps, collar or cuff decoration, jacket closures.
• Accessories: hat fixes, sandal detailing, canvas tote reinforcements.

What tools are included and how easy is installation?

The set contains seven fixing tools suited to punching, setting and securing the included fasteners. With a basic toolkit and a little practice you can achieve clean results; the included post-length options simplify work on single- and double-layer materials.

• Seven setting tools to seat rivets, grommets and cap buttons correctly.
• Two screw post lengths let you choose the right fit for thickness.
• Works with a small hammer or hand press for controlled installation.

Who this kit is for: Caydo 400Set is geared toward hobby leatherworkers, DIY sewists, tailors doing small repairs, and crafters who want versatile fasteners in one organized package. If you regularly mend jackets, jeans, bags or make handmade accessories from thin leather and fabric, this kit supplies the common sizes, colours and tools to get projects finished neatly and affordably.
