J.w. Winco 5T63A11/E Adjustable Clamping Handle 5/16-18

Product Description

The J.W. WINCO 5T63A11/E is a threaded stud adjustable clamping handle designed for machine tool, fixture, and industrial equipment applications where repeated manual clamping and positioning are required. The handle features a ball-end arm that pivots to the operator's preferred angle, allowing access in tight or awkward mounting positions. Key construction details include a steel stud with black oxide finish, a 5/16-18 threaded stud measuring 2.48 inches in length, and a handle arm spanning 2.32 inches. The knob body is plastic with a black oxide coated steel handle arm, keeping overall weight low while maintaining rigidity under clamping loads.

This handle is suited for light-to-medium clamping duty on machine tables, jigs, fixtures, enclosures, and adjustment mechanisms in industrial and manufacturing environments. The 5/16-18 thread is a standard inch-series size common across a broad range of threaded inserts, weld nuts, and drilled-and-tapped assemblies. Machinists, machine builders, and maintenance technicians install this type of handle as an OEM-style replacement or upgrade on manual positioning equipment. Its DIN 319 compliance makes it a direct substitute in metric-designed equipment that also incorporates inch-thread fastening points.

Key Features

• Adjustable ball-end handle arm pivots at 20-degree increments for flexible positioning

Compatibility

Designed as a DIN 319 compliant threaded stud adjustable clamping handle for use with standard 5/16-18 tapped holes in machine fixtures, jigs, enclosures, and industrial positioning equipment.

Installation Notes

Installation is performed by threading the stud directly into a pre-tapped 5/16-18 hole; no special tools are required beyond a wrench or pliers applied to the stud flats if torque is needed. Ensure the mating thread is clean and free of debris before installation. Power down or de-energize any machine or equipment before servicing clamping hardware on moving or adjustable components. Do not exceed the load rating appropriate for a 5/16-18 fastener in the mating material.
