Electro Hardware P545M12F21-632 Female Hex Standoff 6-32

Product Description

The ELECTRO HARDWARE P545M12F21-632 is a female hex circuit board standoff designed to create fixed spacing between a PCB and a mounting surface or between stacked boards. It accepts a 6-32 threaded fastener on the female end and measures 0.75 inches in overall length with a hex body width of 0.25 inches across flats. Constructed from Grade 2 steel with a zinc-plated clear chromate finish, this standoff meets ASTM B633 Type 1 and QQ-S-633 finish standards. Electronics technicians, industrial electricians, and control panel assemblers use these fasteners when building or servicing circuit board assemblies that require precise, repeatable standoff height.

This standoff is suited for use in circuit board mounting applications across residential and commercial control panels, HVAC equipment boards, industrial automation enclosures, and general electronics assemblies. The 6-32 thread size is one of the most common fastener sizes in PCB and enclosure applications. The inch-system dimensions make it a straightforward fit in domestic equipment manufactured to imperial tolerances. Install technicians typically use these when replacing damaged standoffs during board-level service or when assembling new control panel builds.

Key Features

• Female 6-32 threaded hex standoff for circuit board spacing and support
• 0.75 inch overall length provides consistent board-to-surface clearance
• Hex body at 0.25 inches across flats allows standard hex driver installation
• Grade 2 steel construction for reliable mechanical strength in panel environments
• Zinc-plated clear chromate finish meets ASTM B633 Type 1 and QQ-S-633 standards for corrosion resistance
• Length tolerance of -0.005 to +0.005 inches ensures consistent stack height across multiple standoffs

Compatibility

Designed as an OEM-style replacement or new-installation component for circuit board assemblies using 6-32 threaded fasteners and requiring a 0.75 inch standoff height in inch-system applications.

Installation Notes

Installation is typically performed by electronics technicians or licensed electricians during control board service or panel assembly. De-energize all circuits and discharge any capacitors before handling circuit boards or standoff hardware. A hex driver or nut driver sized to 0.25 inches across flats is required for proper torque-free hand-tight seating. Avoid over-tightening, which can strip the 6-32 female threads or crack the board mounting hole.
