20 PCS 1/4-20 X 1/2 Socket Head Cap Screws - Black Oxide 12.9 Grade Alloy Steel | Coarse Thread UNC Screws

About This Product

Hey DIYers and mechanics, these socket head cap screws are seriously sturdy little fasteners! You get 20 pieces of 1/4-20 x 1/2 inch screws with that cool black oxide finish that looks professional and provides some rust resistance. The 12.9 grade alloy steel is no joke - these are high-strength screws that can handle serious torque without stripping or breaking. The coarse UNC threads bite nicely into materials, and the socket head design means you can really crank them down with an Allen wrench (takes 3/16 inch drive). Perfect for machinery, automotive work, furniture assembly, or any project where you need reliable, high-strength fasteners. The black oxide coating gives them decent corrosion resistance for indoor use, though for outdoor projects you might want stainless steel. At half an inch long, they're great for medium-thickness materials where you need solid holding power. The package of 20 means you've got plenty for your current project and some spares for the next one. Seriously quality screws at a great price!
