Electro Hardware 1427M12F21-1032 Hex Standoff 10-32

Product Description

The ELECTRO HARDWARE 1427M12F21-1032 is a male-female hex circuit board standoff designed to create fixed spacing between PCBs and mounting surfaces in electronic assemblies. Machined from Grade 2 steel with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-S-633 standards, this standoff provides reliable corrosion resistance in typical indoor environments. The hex body measures 0.25 inches across flats and 0.625 inches in overall length. The male threaded post and female threaded bore are both sized to the 10-32 thread standard. Electronics assemblers and field service technicians install these fasteners wherever stacked PCB configurations require controlled, repeatable standoff height.

This standoff is used in residential and commercial electronic control assemblies, HVAC control boards, industrial panel builds, and general PCB mounting applications. The male-female configuration allows multiple standoffs to be threaded in series, enabling flexible stacking arrangements. The 10-32 thread is a common pitch in PCB hardware and mates with standard 10-32 screws and threaded inserts used throughout the electronics and controls industries. The hex body shape allows installation and removal with standard hex drivers or nut drivers, making it practical for service environments where access may be limited.

Key Features

• Male-female thread configuration supports stackable PCB standoff assemblies
• 10-32 thread size matches the most common PCB fastener pitch in control board applications
• Grade 2 steel construction with zinc-plated finish per ASTM B633 Type 1 and QQ-S-633
• Hex body at 0.25 inches across flats accepts standard nut drivers for easy installation
• 0.625 inch overall length with 0.25 inch body length and 0.375 inch thread length
• Length tolerance held to plus or minus 0.005 inches for consistent board spacing

Compatibility

Designed as an OEM-style replacement or new-installation fastener for circuit board assemblies requiring 10-32 male-female hex standoffs with a 0.625 inch overall length.

Installation Notes

Installation is typically performed by electronics technicians or control board service professionals. Disconnect all power to the control assembly before removing or installing standoffs. Use a properly sized nut driver or hex wrench matched to the 0.25 inch across-flats dimension to avoid rounding the hex body. Do not over-torque; thread engagement depth is limited by the internal female bore length, and excessive force can strip the 10-32 threads or damage the PCB mounting hole.
