Electro Hardware P521M04F16-1032 Round Female Standoff

Product Description

The ELECTRO HARDWARE P521M04F16-1032 is a round female standoff designed for use in panel assemblies, electronic enclosures, and mechanical fastening applications where precise spacing and a secure threaded connection are required. Machined from aluminum to the T-3 material grade, this standoff features a 10-32 fully threaded female bore with a thread depth of 1 inch. The overall length is 0.375 inches and the outside diameter is 0.25 inches. A bright anodized finish provides corrosion resistance and a clean appearance. This part meets the QQ-A-225A Comp 2 standard and is suited for installations where lightweight metal hardware is specified.

This standoff is used in residential and commercial electrical panel builds, electronic chassis fabrication, control enclosure assembly, and similar trade applications. Electricians, panel builders, and electronic assembly technicians install these standoffs to maintain consistent spacing between PCBs, sub-panels, or mounting plates. The fully threaded female bore accepts a 10-32 fastener from either end, providing flexible attachment options in tight assemblies. This part is sold individually with a minimum order quantity of 5 units.

Installation Notes

Installation is typically performed by electricians or panel assembly technicians using a hex driver or appropriate spanner tool. Power down and de-energize all equipment before installing or removing standoffs in live enclosures. Follow applicable NEC guidelines for hardware used inside electrical panels or control cabinets. Do not overtighten mating fasteners into the aluminum threads, as this material is softer than steel and susceptible to thread damage.
