Big eff-off screw heads to set your hat on after a long day. Hang things from them, learn from them, admire them.
Each History Screw gives you its name, date of invention, standard sizes – and a place to hang your coat. Mount on the wall of a garage, workshop, kid’s room, or anywhere, really. Each set of 3 comes with a Robertson, Phillips, and a Slot. 3.5” diameter.
