QYD12A-80 - Williams - 3/8" Square Drive 80‑Tooth Ratcheting Torque Head – “Y” Shank

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.
