Electro Hardware A3594 Round Aluminum Handle Knob

Product Description

The ELECTRO HARDWARE A3594 is a round aluminum handle knob designed for use in light-duty mechanical and industrial applications. Built from aluminum with a plain finish, this knob offers a clean, uncoated surface suited for environments where a no-frills grip component is needed. It features a 1.5-inch projection and an 8-32 threaded stud for straightforward mounting to panels, equipment housings, or light machinery. The Series A designation places it within a standardized product family. Machinists, equipment assemblers, and maintenance technicians typically install this type of hardware during panel fabrication or equipment servicing.

This round handle knob is used in general industrial and mechanical assembly contexts, including control panels, enclosures, light machinery, and instrumentation. Its aluminum construction keeps weight low while providing adequate durability for indoor and light-duty applications. The plain finish accepts secondary coatings if needed. The 8-32 thread size is a common standard in small equipment assemblies, making this knob a practical replacement or new-installation choice for panel builders and maintenance pros working on similarly threaded hardware.

Installation Notes

Install using standard hand tools appropriate for 8-32 threaded fasteners. De-energize or power down any equipment before servicing panel hardware or replacing knobs on live enclosures. Verify thread engagement depth is sufficient to ensure secure seating without bottoming out. Follow applicable equipment manufacturer guidelines and relevant OSHA or facility safety protocols during installation.
