Electro Hardware 1443M12F21-832 Hex Standoff 8-32 1-1/8 in

Product Description

The ELECTRO HARDWARE 1443M12F21-832 is a male-female hex circuit board standoff designed to create fixed spacing between printed circuit boards or between a board and a chassis panel. Machined from Grade 2 steel with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-S-633 standards, this standoff accepts an 8-32 thread on both the male and female ends. The overall length is 1.125 inches with a hexagonal body measuring 0.25 inches across flats. The hex body shape allows installation and removal with standard open-end or socket wrenches, making it a reliable choice for panel assembly, electronics enclosures, and equipment rack builds.

This standoff is used in applications where rigid, threaded board-to-board or board-to-panel separation is required. Typical installations include industrial control panels, HVAC control board assemblies, electrical enclosures, and electronic equipment chassis. The male end threads into a tapped hole or mates with a hex nut, while the female end receives a machine screw to secure the next board or cover layer. The zinc-plated finish provides corrosion resistance suitable for indoor environments.

Key Features

• Male-female hex configuration for stackable circuit board mounting
• 8-32 unified coarse thread on both ends for broad fastener compatibility
• Overall length of 1.125 inches with a body length of 0.75 inches
• 0.25 inch width across flats allows wrench-driven installation
• Grade 2 steel construction with ASTM B633 Type 1 zinc-plated finish
• Meets QQ-S-633 federal specification for zinc electroplating on steel

Compatibility

Designed as a standard 8-32 male-female hex standoff for use in circuit board assemblies, electrical enclosures, and control panel builds requiring threaded steel spacers with a 0.25 inch hex body.

Installation Notes

Install using an open-end wrench, box wrench, or hex socket sized to the 0.25 inch flats. De-energize and discharge all circuits before handling circuit boards or standoffs in live enclosures. Avoid over-torquing, as Grade 2 steel threads can be damaged by excessive force. Follow applicable NEC or equipment-manufacturer guidelines for fastener specifications in control panel assemblies.
