Home of the Screw Chek’r

Valuable time and money is lost each year by mechanics, maintenance people and do-it-yourselfers using the wrong size screws. Now an easy-to-use, foolproof tool eliminates these problems.

With precision machine threads, the Screw Chek’r/Identifier gives you all the information you need to accurately identify all types of screws in both inch and metric sizes - machine screws, bolts, wood screws, sheet metal screws, and even cotter pins and rivets.

Crafted in America with pride, the Screw Chek’r/Identifier fits easily in your toolbox for convenient use whenever you need it. Manufactured from either hi-impact styrene or heavy gage satin chrome plated steel. The Screw Chek’r/Identifier can be imprinted with your company logo or message.
