Electro Hardware 1431M12F21-1032 Hex Board Standoff 10-32

Product Description

The ELECTRO HARDWARE 1431M12F21-1032 is a male-female hex circuit board standoff designed to create fixed spacing between printed circuit boards and mounting surfaces or between stacked boards. The standoff features a 10-32 thread on both the male and female ends, an overall length of 0.75 inches, and a hex body width across flats of 0.25 inches. Manufactured from Grade 2 steel with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-S-633 standards, this fastener provides corrosion resistance suitable for enclosed electronic enclosures. It is typically installed by electronics technicians, HVAC control board service technicians, and electricians during panel assembly or board replacement work.

This standoff is used in applications where a circuit board must be mechanically secured and electrically isolated from a chassis or secondary board. The 3/8-inch body length and 3/8-inch thread length make it well suited for light-gauge panel assemblies and PCB mounting in residential and commercial HVAC control enclosures, electrical panels, and industrial control boxes. The hex body profile allows installation and removal with a standard nut driver or wrench without the need for specialized tooling.

Key Features

• Male-female configuration allows stacking or chassis-mount PCB standoff in a single fastener
• 10-32 thread size on both ends for standard circuit board hardware compatibility
• Hex body profile accepts a 1/4-inch nut driver or wrench for easy torque application
• Grade 2 steel construction with zinc-plated finish meets ASTM B633 Type 1 and QQ-S-633 corrosion standards
• Overall length of 0.75 inches with a 3/8-inch body and 3/8-inch threaded male post
• Length tolerance held to plus or minus 0.005 inches for consistent board spacing

Compatibility

Designed as a standard 10-32 male-female hex circuit board standoff suitable for PCB mounting applications requiring 0.75-inch overall spacing in inch-measurement assemblies.

Installation Notes

Power down all equipment and discharge any stored energy before servicing circuit boards or control enclosures. Use a 1/4-inch nut driver or appropriately sized wrench on the hex body to seat the standoff without over-tightening, which can crack PCB mounting holes. Follow applicable NEC guidelines when working inside electrical enclosures. Confirm thread engagement depth on both the male post and female thread before final assembly to ensure secure board support.
