Hotop 50pcs Copper Rivet and Burr Washers for Leather Work #9 and #12 Brass Rivets with Setting Tool and Hole Punch Cutter Kit Review (2026)

Who copper rivets and burrs are for

This kit is aimed at makers building belts, straps, tack, dog collars and heavier bags where hardware needs to survive real pulling and flexing rather than just sit decoratively. Copper rivets set with a burr washer form a mechanical connection that clamps the leather layers together far more securely than a tubular rivet pressed shut with a hammer, which is why saddlers and strap makers have used this style for generations. The kit includes 24 rivets and 24 burrs split across #9 and #12 sizes, plus a setting tool and a hole punch cutter, so a first time buyer has everything needed to start setting rivets without sourcing separate tools.

What is actually in the box

The kit pairs copper rivets sized around 10 by 3.3 by 19 millimeters and 10 by 3.3 by 14 millimeters with matching copper burrs roughly 3.3 millimeters on the inner diameter and 9 millimeters on the outer diameter, covering the #9 and #12 sizing common in leathercraft supply catalogs. The setting tool measures about 4.7 by 0.79 by 0.47 inches and is made of stainless steel, while the hole punch cutter is steel with a roughly 3.5 millimeter cutting diameter and a polished surface. Copper is used for both the rivets and burrs because it resists corrosion and will not snap the way some plated alternatives can under stress.

Setting a copper rivet and burr

A hole is first cut through the layered leather with the included punch, sized to the rivet shaft. The rivet is pushed through from the back, the burr washer is slipped over the exposed post from the front, and the setting tool is used to peen the post down over the burr, drawing the two pieces of leather together as it flattens. This takes a few more steps than a snap rivet, which just needs a hammer and two dies, and getting a clean, flush burr takes some practice trimming the post to the right length before peening. Once set, the joint does not come apart the way a poorly seated tubular rivet can.

Copper burrs versus tubular rivets

Compared with tubular double cap rivets, which are popular in kits like the Jetmore or Selizo sets, copper rivet and burr construction holds under load better because the burr clamps mechanically rather than relying on a soft metal cap folding over cleanly. That strength comes at the cost of speed, since tubular rivets can be set in one hammer strike with a simple die set, while copper rivets need the post trimmed and peened by hand. For decorative work on wallets or small accessories where color options matter more than pull strength, tubular rivet kits with multiple colors are usually the easier and faster choice.

Verdict and who needs a bigger kit

For belts, collars, straps and bags that need hardware to hold under real tension, this 50 piece kit in two practical sizes with the setting tool and hole punch included is a solid starting kit that does not require buying separate tools first. The tradeoff is that setting copper rivets takes more time and a little practice compared with tubular snap rivets, and 50 pieces will run out quickly on a production batch of multiple bags or belts. Makers who need high volume or prefer a range of decorative colors should look at a larger tubular rivet kit instead of this copper focused set.
