Electro Hardware P505M12F21-632 Hex Standoff 6-32 1/8 in

Product Description

The ELECTRO HARDWARE P505M12F21-632 is a female hex circuit board standoff designed to create precise, repeatable spacing between PCBs and mounting surfaces in electronic assemblies. Machined from Grade 2 steel with a zinc-plated clear chromate finish meeting ASTM B633 Type 1 and QQ-S-633 standards, this standoff delivers corrosion resistance suitable for control board and panel applications. The hex body profile allows wrench engagement for secure, torque-controlled installation. With an overall length of 0.125 inches and a width across flats of 0.25 inches, it is sized for compact, low-profile board-mounting configurations common in HVAC control boards, electrical panels, and similar assemblies.

This standoff is used wherever a female-threaded 6-32 hex spacer is required to mount or stack circuit boards in residential and commercial control enclosures, electrical panels, and electronic equipment assemblies. It is a standard inch-series fastener appropriate for OEM board assemblies and field service replacement on any equipment using 6-32 threaded hardware. Typical installers include HVAC technicians, electricians, and electronics assembly technicians working on control board replacements or panel builds.

Key Features

• Female 6-32 threaded interior accepts standard 6-32 machine screws for board-to-board or board-to-chassis stacking
• Hex body profile allows wrench or nut driver engagement for secure installation in tight enclosures
• Grade 2 steel construction provides mechanical strength appropriate for PCB mounting applications
• Zinc-plated clear chromate finish meets ASTM B633 Type 1 and QQ-S-633 for corrosion resistance
• Compact 0.125-inch overall length suits low-profile, space-constrained board mounting configurations
• Inch-series measurement system ensures compatibility with standard 6-32 fastener tooling and hardware

Compatibility

Designed as a standard inch-series 6-32 female hex standoff for use in any PCB mounting application requiring 6-32 threaded hardware and a 0.125-inch standoff height.

Installation Notes

Installation is performed by electricians, HVAC technicians, or electronics assembly technicians during control board mounting or replacement. Power down all equipment and discharge any capacitors before servicing control boards or panel assemblies. Use a nut driver or wrench sized for 0.25-inch across flats to seat the standoff without overdriving. Follow applicable NEC guidelines and equipment manufacturer instructions when working inside electrical enclosures.
