Electro Hardware 1447M03F21-1032 Hex Standoff 10-32

Product Description

The ELECTRO HARDWARE 1447M03F21-1032 is a male-female hex circuit board standoff used to create controlled spacing between PCBs, chassis panels, and mounting surfaces in electronic assemblies. Threaded 10-32 on both ends, it accepts a machine screw on the male end and a mating standoff or fastener on the female end, allowing stackable configurations. The body is brass with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards. Overall length is 1.25 inches with a hex body measuring 0.875 inches and a width across flats of 0.25 inches. Electricians, electronics technicians, and control panel fabricators install these during board-level assembly work.

This standoff is suited for use in residential and commercial control panels, HVAC circuit board mounting, electrical enclosures, and industrial PCB assemblies where precise board-to-board or board-to-chassis separation is required. The 10-32 thread size is a common fastener standard in control board and electronics assembly applications. The hex body allows installation and removal with a standard hex wrench or nut driver, making it practical in tight enclosures where finger access is limited.

Key Features

• Male-female thread configuration allows stackable standoff assemblies
• 10-32 thread size with 0.375 inches thread length on the male end and 0.5 inches thread depth on the female end
• Hex body shape with 0.25 inches width across flats for wrench-driven installation
• Brass construction with zinc-plated finish per ASTM B633 Type 1 and QQ-B-626 Comp 22
• Overall length of 1.25 inches with a body length of 0.875 inches
• Length tolerance of -0.005 to 0.005 inches for consistent spacing in precision assemblies

Compatibility

Designed as an OEM-style hardware fastener for circuit board and control panel assemblies using 10-32 threaded mounting systems.

Installation Notes

Installation is performed by electricians or electronics technicians during control panel fabrication or board-level service. Power down and de-energize all circuits before working inside any enclosure. Use a hex wrench or nut driver sized to the 0.25 inches width across flats to seat the standoff without overtightening, which can crack the brass body or strip the threads. Follow applicable NEC guidelines when installing standoffs inside energized enclosures.
