Williams® 1/2" Fixed Square Drive Heads, SAE J-Shank with Interchangeable Torque Heads

Features: Chrome plating provides increased protection from rust and corrosion Drive handles provide extra leverage with greater strength than ratchets Square drive slides on T-Handles for versatility Flex handle flex drive swivels 110° in either direction Spring and plunger socket retention

Features: Provides the operator with nut-turning power that requires only a fraction of the force required when using conventional tools Input and output rotation is in the same direction Reaction bar rotation is opposite to input direction and must rest securely against a rigid object to withstand the generated reaction force By removing 4 screws, heads may be easily disassembled for inspection, cleaning and lubrication

Features: Designed where high torques are necessary for fastening or breaking out stubborn fasteners Allows operator safe and easy means of producing torque for job requirements Precision planetary gear multiplies the operator's input from standard torque wrenches Can also multiply the torque from air-driven (non-impact) wrenches

Features: Factory Pre-Set models are set at the factory to the customer's specified torque setting and are furnished with a Certificate of Calibration Simple, easy to use design Ruggedly built for years of reliable service Operates bi-directionally Accuracy: ± 6% of indicated value, CW, from 20% to 100% of the full scale
