Electro Hardware P529M07F16-440 Round Female Standoff

Product Description

The ELECTRO HARDWARE P529M07F16-440 is a round female standoff designed for fastening and spacing applications in electrical panels, control enclosures, and electronic assemblies. Machined from 18-8 and Grade 303 stainless steel with a bright finish, this standoff offers corrosion resistance suited for both indoor and light industrial environments. It features a 4-40 thread size, an overall length of 0.5 inches, an outside diameter of 0.25 inches, and is fully threaded through a 0.5-inch thread depth. Licensed electricians, panel builders, and electronics assembly technicians commonly install this hardware during board mounting and component spacing work.

This standoff is used in applications requiring a compact, fully threaded female receiver for 4-40 machine screws. Typical install scenarios include PCB mounting, electrical enclosure panel work, control board assemblies, and light-duty electronic chassis builds. The 0.5-inch overall length and 0.25-inch outside diameter make it well suited for tight-clearance layouts where consistent spacing and secure thread engagement are required.

Compatibility

Designed as an OEM-style replacement or direct-fit standoff for assemblies requiring a 4-40 female thread, 0.5-inch overall length, and 0.25-inch outside diameter in a round stainless steel body.

Installation Notes

Installation is typically performed by licensed electricians or electronics assembly technicians during panel or board mounting work. Power down and de-energize any associated equipment before installing or removing standoffs in live enclosures. Use appropriately sized 4-40 machine screws and avoid over-torquing, which can damage the thread or distort thin panel material. Follow applicable NEC guidelines when installing within electrical enclosures.
