The Spiralock thread form features a 30° wedge ramp at the root of the thread that locks the mating bolt under vibration without adhesives or locking inserts, distributing clamp load evenly across all engaged thread flanks to minimize fatigue failure and improve reusability. Each tap is manufactured from High Speed Steel (HSS) with a Titanium Nitride (TiN) physical vapor deposition coating (gold finish) for increased surface hardness and lubricity, while the shank carries a black-oxide steam-temper finish; flute geometry is straight (SPL = Spiralock, 3 = 3 flutes, T10 = tolerance class, B = bottoming chamfer style) with a 3-flute configuration suited for through and blind hole applications. Taps must be used with a Spiralock-specific oversize drill to achieve the required minor diameter of 0.220–0.227 in, and threads must be inspected exclusively with Spiralock gauges; compatible with standard UNF 1\/4-28 bolts and screws upon assembly.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid
