Electro Hardware P577M12F21-632 Female Hex Standoff 6-32

Product Description

The ELECTRO HARDWARE P577M12F21-632 is a female hex circuit board standoff with a 6-32 thread size and a 1-1/4 inch overall length. It features a hex body shape with a 1/4 inch width across flats, making it easy to install and torque with standard hex tooling. Constructed from Grade 2 steel with a zinc-plated clear chromate finish that meets ASTM B633 Type 1 and QQ-S-633 standards, this standoff provides reliable corrosion resistance in typical electronics and electrical enclosure environments. It is designed for use in securing circuit boards at a fixed standoff height within panels, enclosures, and electronic assemblies.

This standoff is suited for residential and commercial electrical, control panel, and electronics applications where circuit boards must be mounted at a precise distance from a chassis or panel surface. The female thread accepts a mating male screw from the board side, allowing secure two-point fastening. Electricians, control panel builders, and electronics technicians commonly use this type of standoff when assembling or servicing printed circuit board assemblies inside HVAC control enclosures, electrical panels, and similar equipment.

Key Features

• Female 6-32 thread accepts standard mating machine screws for secure PCB mounting
• 1-1/4 inch overall length provides consistent standoff height between board and mounting surface
• Hex body shape with 1/4 inch width across flats allows installation and removal with standard hex wrench or nutdriver
• Grade 2 steel construction with zinc-plated clear chromate finish for corrosion resistance
• Meets ASTM B633 Type 1 and QQ-S-633 finish standards
• Length tolerance of -0.005 to +0.005 inches ensures consistent fitment in precision assemblies

Compatibility

Designed as a standard inch-series female hex circuit board standoff for use in electrical enclosures, control panels, and electronic assemblies requiring a 6-32 threaded mount point.

Installation Notes

Installation is typically performed by electricians or control panel technicians. De-energize all circuits before working inside any electrical enclosure or control panel. Use a hex wrench or nutdriver sized to the 1/4 inch width across flats to drive and seat the standoff securely without overtightening. Follow applicable NEC guidelines when installing or servicing circuit board assemblies inside electrical enclosures.
