640 Sets Mixed Color Leather Rivets Kit Mixed Size Double Cap Rivets with Rivet Press Setter Tool, 4 Colors 2 Sizes Review (2026)

What comes in this rivet kit

This kit bundles 640 sets of double cap rivets together with a rivet press setter tool, packaged in a plastic case for storage and sorting. The rivets are offered in 4 cap colors, described as silver, gold, bronze and gunmetal, across 2 sizes, giving buyers some flexibility to match rivet color to different hardware finishes on a bag, belt or accessory without buying separate color specific kits. Double cap rivets use a domed cap on both the front and back of the material, which gives a finished, symmetrical look compared to rivets with a flat back, and they are set by hammering or pressing the two halves together over a punched hole.

Rivet construction and finish

The rivets in this kit combine a copper cap surface with an iron tube core, a common construction for budget rivet kits that keeps cost down while still giving the visible cap a metallic, non rusting appearance under normal use. Because the color is a plated or coated finish over the copper and iron base rather than solid brass or solid copper throughout, very heavy wear or repeated flexing at the rivet site can eventually show the base metal underneath on some units, which is typical of rivets in this price range rather than a defect specific to this kit. For decorative and moderate structural use on leather and canvas goods, this construction holds up well.

Using the included press setter

A rivet press setter tool is included, which is meant to apply even pressure across the cap as it seats over the punched hole, generally giving a cleaner, more consistent result than tapping a rivet down freehand with a hammer and a separate anvil and setter punch. Using the press correctly still requires punching a hole sized to the rivet's post diameter first, then aligning the two halves squarely before pressing, since a rivet set at an angle can crack the cap or fail to seat all the way. Included setter tools in bundled kits are functional for occasional and moderate use, though a heavier duty standalone rivet press is worth considering for anyone setting rivets daily in a production setting.

Two sizes and thickness limits

This kit ships with 2 rivet sizes rather than the 3 sizes some competing kits include, which narrows the range of leather or fabric stack thickness the rivets can comfortably span. Rivets need a post long enough to pass through the full thickness of material being joined and still leave enough length to peen or press the second cap down securely, so a kit with only 2 sizes may come up short when riveting through multiple layers of thick leather, such as a folded strap end or a reinforced bag bottom. For single layer leather, canvas, or typical belt and strap thicknesses, the 2 included sizes generally cover the job.

Who this kit suits

This is a solid choice for hobbyists and small shop makers who want a large supply of rivets in varied colors on hand along with a setter tool, rather than buying rivets and tools separately or in small batches. The 640 count means color and size will not run out quickly across many small projects like wallets, dog collars, belts, and bag hardware. Buyers who need a rivet size matched to thicker, multi layer leather stacks, or who want solid brass rivets rather than a plated copper and iron construction, should look at a kit built specifically around a longer post length or premium solid metal rivets instead of this general purpose assortment.
