Electro Hardware P553M01F21-632 Female Standoff 6-32

Product Description

The ELECTRO HARDWARE P553M01F21-632 is a round female standoff fastener designed to create precise spacing and threaded mounting points in panel assemblies, enclosures, and electronic or electrical equipment. This standoff measures 0.875 inches overall length with a 0.25 inch outside diameter and is fully threaded to a 1 inch thread depth using a 6-32 thread form. The body is machined from brass and finished with zinc plating per ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, providing corrosion resistance appropriate for indoor electrical and control panel applications. Electricians, panel builders, and equipment assemblers install these as standard hardware in enclosure builds and PCB mounting configurations.

This female standoff is suited for residential and commercial panel fabrication, electrical enclosure assembly, and general industrial fastener applications where a precise standoff distance and secure threaded connection are required. The fully threaded interior accepts a 6-32 male fastener from either end, making it versatile for through-bolt or blind-mount installations. Its compact 0.25 inch OD fits standard standoff clearance holes in sheet metal and fiberglass panels commonly found in control and distribution equipment.

Compatibility

Designed as a standard 6-32 round female standoff for use in electrical enclosures, control panels, and PCB mounting assemblies that require inch-series threaded hardware.

Installation Notes

Installation is performed by electricians, panel builders, or equipment assemblers using standard hand tools appropriate for 6-32 threaded fasteners. De-energize all equipment before installing or removing standoffs in live panels or enclosures. Avoid over-torquing brass standoffs, as the material is softer than steel and susceptible to thread damage under excessive force. Follow applicable NEC guidelines and equipment manufacturer instructions for enclosure hardware requirements.
