Metric Hex Tap Bolts
Fully Threaded Metric Hex Head Bolts
Hex Tap Bolts, commonly referred to as Hex Bolts, or simply Tap Bolts are hex head bolts with a full thread (tip to underneath head) regardless of the bolt length. Hex Tap Bolts differ from Hex Cap Screws in that Hex Cap Screws fully threaded in shorter lengths (usually around up to 1-1/2 inch, depending upon the bolt diameter), and partially threaded with a shoulder beneath the fastener hex head in longer lengths. Hex Tap Bolts are fully threaded to the underside of the bolt head, regardless of length.
