QJRXS18A - Williams - 9/16" 6‑Point Flare Nut Torque Head

The Williams QJRXS18A 6‑Point Flare Nut Torque Head is designed for controlled torque on 9/16" flare‑style fittings commonly used in hydraulic systems, fuel lines, and industrial tubing. Its open‑side flare nut design allows the head to slip directly over tubing, making it ideal for tight, recessed, or obstructed spaces.

Constructed from high‑strength alloy steel, this torque head withstands daily professional use while delivering consistent, precise torque values. The 6‑point geometry provides a strong, even grip on fittings, reducing rounding and improving torque accuracy. This model connects seamlessly to Williams J‑shank interchangeable torque wrench systems.
