3/16 in Nut Driver for SAE Fasteners

This Klein Tools 630-3/16 nut driver fits 3/16 inch SAE fasteners. The hollow round shank provides three inches of bolt clearance. A cushion grip adds comfort and twist resistance during use. The chrome plated handle resists corrosion on the job site.

Three Inch Shank Depth and Clearance

The three inch shank length reaches recessed nuts and allows three inches of bolt clearance through the hollow body. This depth handles typical automotive and electrical panel hardware. Very deep wells or longer threaded rods exceed the available clearance. Extremely tight clearances may prevent the shank from engaging fully.

Cushion Grip and Non-Magnetic Tip

The cushion grip reduces hand fatigue and improves torque control without adding bulk. The tip is non-magnetic so it will not hold fasteners during placement. No insulation or ESD protection is included for live electrical work. The tool is restricted from sale in California due to Proposition 65 chemical warnings.
