Electro Hardware P577M04F16-1032 Round Female Standoff

Product Description

The ELECTRO HARDWARE P577M04F16-1032 is an aluminum round female standoff designed to create precise spacing between circuit boards, panels, and structural components in electronic and mechanical assemblies. This standoff features a 10-32 internal thread with a 1 inch thread depth and is fully threaded throughout the body. The outside diameter measures 0.25 inches and the overall length is 1.25 inches. Finished with a bright anodized coating, it meets QQ-A-225A Comp 2 material standards and is manufactured to a length tolerance of -0.005 to 0.005 inches. Electricians, electronics technicians, and panel builders install this hardware in control panel fabrication, PCB mounting, and enclosure assembly work.

This standoff is suited for use in both light commercial and industrial applications where consistent board or panel separation is required. It is commonly installed in electrical control enclosures, instrumentation panels, and electronics chassis where a reliable, corrosion-resistant aluminum fastener is needed. The inch-based sizing and standard 10-32 thread make it compatible with a wide range of off-the-shelf hardware and mounting hardware used in standard control and electronics assembly work.

Installation Notes

Install using a hex driver or appropriately sized wrench sized to the 0.25 inch outside diameter. De-energize all equipment before working inside any electrical enclosure or control panel. Avoid over-torquing into aluminum threads, as the material is softer than steel and susceptible to thread stripping. Installation should follow applicable NEC guidelines when used inside listed electrical enclosures.
