Gibraltar G3747-27-G Gear Lever Arm Shaft 3/8-16

Product Description

The GIBRALTAR G3747-27-G is a steel gear lever arm shaft designed for use in mechanical control and positioning applications. This shaft-only component features a 3/8-16 threaded stem with a 0.47-inch shaft diameter and a 2.7-inch shaft length. The 1/2-inch thread length provides secure engagement with mating hardware. With no knob attached, this part is intended for use where a custom handle, knob, or lever will be installed separately. Fabricated from steel, it delivers the durability required in demanding industrial and trade service environments. Installers and maintenance technicians working on gear control assemblies will find this a direct-fit shaft replacement or build component.

This shaft is suited for mechanical gear lever and control arm assemblies found in HVAC equipment, industrial machinery, and similar trade applications where a threaded stem shaft is required. The 3/8-16 thread pattern is a common standard pitch, making this component compatible with a broad range of threaded hardware in control linkage and lever arm configurations. It is supplied as the shaft only with no knob or handle included, allowing the installer to pair it with the appropriate control knob or lever for the specific application.

Compatibility

Designed as a replacement or build shaft for mechanical gear lever arm assemblies requiring a 3/8-16 threaded stem with a 0.47-inch shaft diameter. Confirm thread pitch, shaft diameter, and shaft length against the existing assembly before installation.

Installation Notes

Installation is typically performed by a qualified maintenance technician or mechanical trades professional. Before servicing any control linkage or gear assembly, de-energize the equipment and relieve any mechanical tension on the lever arm system. Verify thread engagement depth and ensure the mating threaded bore is clean and free of damage before threading the stem. Follow applicable equipment manufacturer guidelines and relevant mechanical codes for the specific application.
