Electro Hardware 1443M03F21-1032 Hex Standoff 10-32

Product Description

The ELECTRO HARDWARE 1443M03F21-1032 is a male-female hex circuit board standoff designed to create fixed spacing between printed circuit boards or between a board and a mounting surface. The standoff measures 1.125 inches in overall length with a hexagonal body that is 0.75 inches long and 0.25 inches across the flats. The male thread and female threaded bore are both 10-32, with a thread depth of 0.5 inches and a thread length of 0.375 inches. Manufactured from brass with a zinc-plated finish, it meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards. Electronics technicians and PCB assembly professionals use these standoffs during board mounting and enclosure builds.

This standoff is suited for use in control board assemblies, electrical enclosures, and electronic equipment where consistent board-to-surface separation is required. The inch-system threading makes it compatible with standard 10-32 fastener hardware commonly used in HVAC control boards, industrial control panels, and general electronics enclosures. The zinc plating provides corrosion resistance in typical indoor installation environments. These are sold individually with a minimum order quantity of 5 units.

Key Features

• Male-female configuration allows stacking or direct mounting to a threaded surface
• Hexagonal body profile accepts a wrench for precise, torque-controlled installation
• Brass construction with zinc-plated finish meets ASTM B633 Type 1 and QQ-B-626 Comp 22
• 10-32 thread size on both male and female ends for compatibility with standard inch-series fasteners
• Length tolerance held to plus or minus 0.005 inches for consistent board spacing

Compatibility

Designed as an OEM-style replacement or new-installation standoff for circuit board assemblies using standard 10-32 inch-series threaded hardware.

Installation Notes

Installation is performed by electronics technicians or electricians during board mounting or enclosure assembly. Power down and de-energize all circuits before handling or installing control boards. Use an appropriately sized hex wrench or nut driver to seat the standoff without over-stressing the board or mounting surface. Follow applicable NEC guidelines when installing control boards within electrical enclosures.
