J.w. Winco 12N63A13/E Adjustable Clamping Handle M12x1.75

Product Description

The J.W. WINCO 12N63A13/E is a metric-size threaded stud adjustable clamping handle designed for use on machine tools, fixtures, jigs, and industrial equipment requiring secure manual clamping. The handle features a steel arm with a ball end and a 20-degree arm angle, allowing the operator to reposition the handle to clear obstructions before tightening. The stud is M12x1.75 thread with a 63 mm threaded length. The steel components carry a black oxide finish. Overall body height is 48.5 mm and the handle arm length is 89 mm. This type of handle is installed by machine builders, tool and die technicians, and maintenance mechanics in manufacturing and fabrication environments.

This adjustable clamping handle is suited for use on machine tool tables, fixtures, enclosures, and adjustment mechanisms where a fixed handle position would interfere with operation or tooling. The threaded stud mounts directly into a tapped hole, making it a straightforward retrofit or OEM replacement on equipment that uses M12x1.75 threaded clamping hardware. The ball-end arm style and adjustable pivot allow the installer to set the handle angle to match the available swing clearance in the application.

Installation Notes

Installation is performed by machine builders, maintenance mechanics, or tool and die technicians. Power down and de-energize any machine before replacing or adjusting clamping hardware. Thread the stud into the tapped hole by hand first to confirm thread engagement before applying torque. Verify that the handle arm swing arc is clear of moving parts, tooling, and guarding before returning the machine to service.
