5/16"-18 x 2-1/2" Hex Head Tap Bolts, Fully Threaded, 316 Stainless Steel

Tap Bolts are hex head bolts threaded up to the head, with a machined point and a fully threaded shank. Tap Bolts are used instead of a stud and nut. Tap Bolts have a tolerance similar to those of cap screws and especially serve as fully threaded cap screws. Stainless steel tap bolts can be used in environments too corrosive for carbon steel tap bolts.
