Electro Hardware 1431M12F21-832 Hex Standoff 8-32

Product Description

The ELECTRO HARDWARE 1431M12F21-832 is a male-female hex circuit board standoff designed to mount and space printed circuit boards within electronic enclosures and control panels. The standoff features an 8-32 thread size with a hex body shape measuring 0.250 inches across the flats. The 3/8-inch body length and 3/8-inch thread length provide a defined, consistent offset between stacked boards or between a board and a mounting surface. Finished in zinc plating per ASTM B633 Type 1 and QQ-S-633, this steel fastener resists corrosion in light-duty indoor environments. It is installed by electricians, panel builders, and electronics technicians during control board assembly or enclosure build-out.

This standoff is suited for residential and commercial control panel assemblies, HVAC control boards, electrical enclosures, and general electronics manufacturing where secure, repeatable board spacing is required. The male end threads into a mounting surface or a female standoff below, while the female end accepts a machine screw from above to secure the next board layer. It is sized for standard 8-32 machine screw applications common in control board and panel wiring assemblies.

Key Features

• 8-32 thread size with male-female configuration for stackable board mounting
• Hex body shape at 0.250 inches across the flats for wrench engagement during installation
• 3/8-inch body length and 3/8-inch thread length for consistent board standoff height
• Steel construction with zinc plating per ASTM B633 Type 1 and QQ-S-633 for corrosion resistance
• Length tolerance of -0.005 to 0.005 inches ensures dimensional consistency across assemblies

Compatibility

Designed as an OEM-style replacement or new-installation fastener for circuit board assemblies requiring 8-32 male-female hex standoffs with a 1/4-inch hex body width and 3/8-inch body length.

Installation Notes

Installation is performed by licensed electricians or panel assembly technicians. Always de-energize and lock out the control panel or enclosure before working on any circuit board mounting hardware. Use an appropriately sized hex wrench or nut driver to engage the hex flats and avoid over-torquing, which can strip the threads or crack the board. Follow applicable NEC guidelines for panel assembly and component mounting.
