Torque Head 3/8" Square Drive 80 Tooth Ratcheting Y Shank - Wrench
Williams QYD12A-80 3/8" Square Drive 80-Tooth Ratcheting Torque Head "Y" Shank
The Williams QYD12A-80 Ratcheting Torque Head is built for technicians who demand smooth operation, precise torque control, and exceptional accessibility in tight industrial environments. Featuring a fine 80-tooth ratchet mechanism, this torque head delivers a minimal swing arc—ideal for confined workspaces where every degree of movement counts.
Designed with a secure "Y"-style shank, the QYD12A-80 attaches rigidly to Williams torque wrenches and torque multipliers, providing stable and reliable torque transmission. The 3/8" square drive makes it compatible with a wide range of small-to-medium industrial sockets, making this head a versatile tool for mechanical maintenance, instrumentation, utilities, aerospace support, and oil & gas field operations.
Constructed from high-strength alloy steel and precision-machined to exact tolerances, the QYD12A-80 is engineered to resist wear, rounding, and torsional stress—ensuring long-lasting performance in demanding applications.
