200pc Assorted Box of UNF Setscrews - 200 bright zinc plated hexagon head setscrews in UNF fine thread, covering 1/4", 5/16" and 3/8" in lengths from 3/4" up to 1.1/2".
A setscrew is threaded all the way to the head rather than part way up the shank, so it grips through the full depth of the joint and holds in a tapped hole where a part threaded bolt would run out of thread. UNF is the fine imperial thread used on classic cars and motorcycles, older tractors and machinery, and anything built before metric took over. The hex head takes an ordinary AF spanner or socket.
