Gibraltar G10-0085-C Lever Knob 1/2-13 Threaded Hole

Product Description

The GIBRALTAR G10-0085-C is a lever knob designed for manual control applications on machinery, fixtures, and industrial equipment. The knob features a 1-7/8 inch head diameter and a 7/8 inch hub diameter, with a 1/2-13 threaded hole for direct bolt-on mounting to threaded shafts or fasteners. Standing 1-9/32 inches high with a 7/8 inch hole depth, this lever knob provides a secure, ergonomic grip point for adjustments, clamping, and positioning tasks. It is installed by machinists, maintenance technicians, and equipment assemblers wherever a hand-operable control point is needed.

This lever knob suits a wide range of light to medium industrial applications including machine tool fixtures, jigs, clamps, workholding devices, and panel assemblies. The 1/2-13 thread size is a standard coarse-thread specification common across North American industrial equipment, making this knob a practical fit for retrofit or replacement installs on existing machinery as well as new fabrication work. It is packaged individually and sold in multiples of 10.

Key Features

• 1-7/8 inch head diameter for a comfortable hand grip
• 1/2-13 threaded hole mount for standard coarse-thread shafts and fasteners
• 7/8 inch hub diameter with 7/8 inch hole depth for secure thread engagement
• 1-9/32 inch overall height for low-profile clearance in tight assemblies

Compatibility

Designed as an OEM-style replacement or direct-install lever knob for industrial machinery, fixtures, and equipment using 1/2-13 threaded shafts or fasteners.

Installation Notes

Installation is performed by threading the knob directly onto a compatible 1/2-13 threaded shaft or stud by hand. Ensure the mating shaft thread is clean and free of debris before installation. Do not use power tools to drive the knob onto the shaft, as over-torquing can damage the threaded insert. Confirm thread engagement depth meets the 7/8 inch hole depth specification for a secure fit.
