Need reliable rivets for your DIY projects? These Yinpecly aluminum semi-tubular rivets are perfect for fastening all kinds of materials—leather, fabric, plastic, rubber, corrugated sheets, you name it. They measure 5mm in diameter (about 0.20”) and 28mm in height (1.10”), with a flat head design that sits flush for a clean finish. Made from lightweight aluminum with a silver-tone finish, they’re strong yet easy to work with. One big plus: semi-tubular rivets need about 1/4 of the force compared to solid rivets, so they’re way easier to apply without bending or buckling. You can even use them as pivot points in moving joints since only the tail swells. Great for permanent fastening with good joint strength, and they can pierce through softer materials without pre-drilling. Pack comes with 100 pieces—plenty for your crafting, repairing, or prototyping needs. Handy, durable, and super versatile!
