Electro Hardware 1443M12F21-632 Hex Standoff 6-32

Product Description

The ELECTRO HARDWARE 1443M12F21-632 is a male-female hex circuit board standoff designed to create fixed spacing between stacked PCBs or between a circuit board and a chassis. The standoff features a 6-32 thread size, an overall length of 1 inch, and a hex body with a width across flats of 0.25 inches. Constructed from Grade 2 steel with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-S-633 standards, it provides corrosion resistance suitable for electronics enclosures and control panel assemblies. Licensed electricians, electronics technicians, and control panel builders typically install these in HVAC control boards, electrical enclosures, and industrial PCB assemblies.

This standoff is used in applications where a threaded male post on one end and a threaded female receptacle on the other end are needed to stack boards at a precise height. The 3/4-inch body length and 1/4-inch thread length on the female end allow for clean, repeatable board spacing. Common install scenarios include residential and commercial HVAC control board assemblies, electrical panel subassemblies, and any application requiring a secure, metal PCB mounting solution with standard 6-32 inch-series threads.

Key Features

• Male-female hex configuration for stackable PCB mounting
• 6-32 thread size, inch-series standard
• Overall length of 1 inch with a 3/4-inch body length
• Grade 2 steel construction with zinc-plated finish
• Meets ASTM B633 Type 1 and QQ-S-633 finish standards
• Hex body profile at 0.25 inches across flats for wrench engagement

Compatibility

Designed as a standard 6-32 inch-series male-female hex standoff for use in circuit board and electronics enclosure applications requiring this thread size and overall length.

Installation Notes

Installation is performed by electronics technicians or licensed electricians working on control boards and panel assemblies. Always de-energize and lock out the equipment before handling circuit boards or standoffs inside live enclosures. A nut driver or open-end wrench sized to 0.25 inches across flats is typically used to torque the standoff into position. Avoid cross-threading by hand-starting all fasteners before applying tool force.
