Electro Hardware P513M12F21-1032 Hex Standoff 10-32

Product Description

The ELECTRO HARDWARE P513M12F21-1032 is a female hex circuit board standoff designed to create precise spacing between PCBs, panels, and chassis surfaces in electronic assemblies. Machined from Grade 2 steel with a zinc-plated clear chromate finish, this standoff meets ASTM B633 Type 1 and QQ-S-633 standards for corrosion resistance and dimensional consistency. The hex body measures 0.25 inches across the flats, and the overall length is 0.25 inches. The female 10-32 threaded interface accepts a standard machine screw, making it a common choice for control boards, terminal blocks, and equipment panels across HVAC, electrical, and industrial applications.

This standoff is suited for light-gauge panel assemblies and circuit board mounting in residential and commercial equipment. Electricians, HVAC technicians, and electronic assembly professionals install these fasteners when securing control boards, relay panels, or PCBs to metal enclosures. The inch-system sizing and standard 10-32 thread make it interchangeable with common fastener inventories on the bench or in the field.

Key Features

• Female 10-32 threaded hex standoff for secure, removable board mounting
• Grade 2 steel construction with zinc-plated clear chromate finish
• Meets ASTM B633 Type 1 and QQ-S-633 corrosion-resistance standards
• Hex body shape allows wrench or nut-driver installation and removal
• Compact 0.25-inch overall length suits tight panel and board clearances
• Length tolerance of -0.005 to 0.005 inches for consistent stack height

Compatibility

Designed as an OEM-style replacement or new-installation standoff for circuit boards and panel assemblies using standard 10-32 inch-series fasteners.

Installation Notes

Installation is performed by electricians or electronics technicians during control board service or panel assembly. Power down and de-energize the equipment completely before removing or installing any circuit board hardware. A nut driver or small open-end wrench sized for 0.25-inch hex flats is the appropriate tool. Avoid over-torquing, as the compact size of this standoff can stress threaded inserts in thin panel stock.
