Electro Hardware 1427M03F21-632 Hex Standoff 6-32

Product Description

The ELECTRO HARDWARE 1427M03F21-632 is a male-female hex circuit board standoff designed to create precise spacing and secure mechanical connections between PCBs and mounting surfaces or stacked boards. Threaded 6-32 on both ends — male post on one end, female threaded bore on the other — this standoff provides a 0.5-inch overall length with a 0.25-inch body length and a 0.25-inch thread length per end. Machined from brass with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, it delivers corrosion resistance and consistent conductivity in electronic assemblies. Width across flats measures 0.25 inches for standard hex driver engagement. Installed by electronics technicians, HVAC controls technicians, and field service engineers during control board assembly or replacement.

This standoff is used in residential and commercial control board assemblies, including HVAC system control panels, electrical enclosures, and industrial PCB mounting applications. It is suited for any application requiring a 6-32 threaded male-female standoff with a 0.5-inch overall length and a hex body that accepts a standard nutdriver or wrench. The brass construction with zinc plating makes it appropriate for indoor environments where mild corrosion resistance is needed without sacrificing conductivity.

Key Features

• Male-female thread configuration — 6-32 male post on one end, 6-32 female threaded bore on the other
• 0.5-inch overall length with 0.25-inch body length and 0.25-inch thread length per end
• Brass construction with zinc-plated finish per ASTM B633 Type 1 and QQ-B-626 Comp 22
• 0.25-inch width across flats for hex nutdriver or wrench installation
• Length tolerance of -0.005 to 0.005 inches for precise PCB stacking clearance
• Thread depth of 0.375 inches on the female end for full thread engagement

Compatibility

Designed as an OEM-style replacement or new-installation standoff for any circuit board assembly requiring a 6-32 male-female hex standoff with a 0.5-inch overall length and 0.25-inch hex body width.

Installation Notes

Install and remove using a 0.25-inch hex nutdriver or appropriately sized wrench — do not use pliers, which can deform the hex flats. De-energize all circuits and discharge any capacitors before servicing control boards or electrical enclosures. Follow applicable NEC guidelines for electrical enclosure work. Do not overtighten; brass standoffs are subject to thread stripping if torqued beyond the rated engagement depth.
