Electro Hardware P521M09F16-632 Female Hex Standoff 6-32

Product Description

The ELECTRO HARDWARE P521M09F16-632 is a female hex circuit board standoff designed to mount and space printed circuit boards within electronic enclosures, control panels, and electrical assemblies. The standoff features a 6-32 female thread and measures 0.375 inches overall length with a 0.25-inch width across the hex flats. Manufactured from 18-8 and Grade 303 stainless steel with a bright anodized finish, it meets the QQ-S-763 fastener standard. Electricians, control panel builders, and electronics technicians use this hardware when stacking or mounting boards at a consistent, secure offset from a chassis or substrate.

This standoff is suited for use in residential and commercial control panels, HVAC circuit board assemblies, electrical enclosures, and similar applications where a compact, corrosion-resistant threaded spacer is required. The hex body profile allows installation and removal with standard hex drivers or wrenches without slipping. The 6-32 thread size is a common designation in low-voltage circuit board mounting across a wide range of electronic and trade equipment.

Key Features

• Bright anodized finish meets QQ-S-763 fastener standard
• Length tolerance of -0.005 to +0.005 inches for precision fitment

Compatibility

Designed as an OEM-style replacement or new-installation standoff for circuit boards using 6-32 threaded mounting points in electrical enclosures and control panel assemblies.

Installation Notes

Installation is performed by electricians or electronics technicians during control panel assembly or circuit board service. Power down and de-energize all circuits before handling or replacing board hardware. Use a correctly sized hex driver or nut driver matching the 0.25-inch width across flats to avoid rounding the hex body. Follow applicable NEC guidelines when working inside electrical enclosures.
