Electro Hardware 1447M03F21-632 Hex Standoff 6-32

Product Description

The ELECTRO HARDWARE 1447M03F21-632 is a male-female hex circuit board standoff designed to create fixed spacing between PCBs, mounting panels, or enclosure surfaces in electronic assemblies. Threaded 6-32 on both ends — male post on one end, female threaded bore on the other — this standoff allows boards to be stacked or secured with standard machine screws. The hex body measures 1/4 inch (0.250 inches) across flats, enabling wrench tightening without slipping. Overall length is 1-1/8 inches (1.125 inches) with a body length of 7/8 inches (0.875 inches). Manufactured from brass with a zinc-plated finish conforming to ASTM B633 Type 1 and QQ-B-626 Comp 22, this fastener delivers corrosion resistance suitable for control board assemblies in HVAC, electrical, and industrial enclosure applications.

This standoff is used in residential and commercial applications wherever circuit boards require secure, repeatable standoff spacing from a chassis or adjacent board. Typical installation scenarios include HVAC control board mounting, electrical panel subassemblies, and industrial equipment enclosures. The 6-32 thread size is one of the most common fastener sizes in PCB mounting hardware, making this standoff a frequent replacement or new-build component for electronics technicians and HVAC service professionals working with control board hardware.

Key Features

• Male-female hex configuration accepts 6-32 machine screw on female end and threads into mating standoff or panel on male end
• 1/4 inch hex width across flats allows standard wrench or nut driver installation
• 1-1/8 inch overall length with 7/8 inch body length and 1/4 inch thread length on male post
• Brass construction with zinc-plated finish meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards
• Length tolerance held to plus or minus 0.005 inches for consistent board spacing
• Inch measurement system; compatible with standard SAE 6-32 fastener hardware

Compatibility

Designed as a standard 6-32 male-female hex circuit board standoff for use in PCB mounting applications requiring inch-series hardware with a 1/4 inch hex body and 1-1/8 inch overall length.

Installation Notes

Installation is typically performed by electronics technicians, HVAC controls specialists, or electricians during control board service or enclosure assembly. De-energize all equipment and discharge any stored capacitor voltage before handling circuit boards or replacing standoffs. Use a properly sized nut driver or hex wrench to seat the standoff without overtightening, which can crack PCB mounting holes or strip brass threads. Follow applicable equipment manufacturer specifications and NEC guidelines when working inside electrical enclosures.
