Electro Hardware 1439M03F21-832 Hex Standoff 8-32

Product Description

The ELECTRO HARDWARE 1439M03F21-832 is a male-female hex circuit board standoff designed to create fixed spacing between PCBs, mounting panels, and enclosure surfaces. Threaded 8-32 on both ends — male on one end, female (tapped) on the other — this standoff allows boards to be stacked or secured with a standard machine screw. It is machined from brass with a zinc-plated finish that meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards. Overall length is 1 inch, with a hex body measuring 0.25 inches across flats. Electronics technicians, panel builders, and control board assemblers routinely install these in HVAC control panels, electrical enclosures, and industrial equipment.

This standoff is suited for use in residential and commercial control panel assemblies where consistent board-to-surface clearance is required. Typical applications include securing circuit boards inside HVAC units, variable frequency drive enclosures, and custom electrical panels. The male-female configuration supports modular stacking, making it practical for multi-board assemblies where repeated service access is expected.

Key Features

• Male-female thread configuration for stackable or surface-mount PCB installations
• 8-32 thread size on both male and female ends
• Hexagonal body shape, 0.25 inches across flats, allows wrench or nut driver installation
• 1 inch overall length with 5/8 inch body length and 7/16 inch thread depth
• Brass construction with zinc-plated finish for corrosion resistance
• Meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards

Compatibility

Designed as an OEM-style replacement or standard hardware component for circuit board mounting applications requiring an 8-32 male-female hex standoff with 1 inch overall length and 0.25 inch hex body width.

Installation Notes

Installation is typically performed by electronics technicians or licensed electricians during panel assembly or control board replacement. De-energize all equipment and discharge any capacitors before working inside electrical enclosures. Use a nut driver or open-end wrench sized for 1/4 inch hex flats to seat the standoff without over-torquing the brass body. Follow applicable NEC guidelines for panel construction and board mounting clearances.
