Electro Hardware 1451M12F21-832 Hex Standoff 8-32 1-3/8 in

Product Description

The ELECTRO HARDWARE 1451M12F21-832 is a male-female hex circuit board standoff designed to create fixed spacing between PCBs, panels, and chassis surfaces in electronic and control system assemblies. Machined from Grade 2 steel with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-S-633 standards, this standoff provides corrosion resistance and reliable thread engagement. The male end is threaded 8-32 for insertion into a board or panel, while the female end accepts a mating 8-32 fastener. Overall length is 1.375 inches with a 1/4-inch hex body for wrench-driven installation.

This standoff is suited for mounting and spacing printed circuit boards inside HVAC control cabinets, electrical enclosures, and other equipment where secure, stackable hardware is required. The hex body shape allows installation and removal using standard nut drivers or hex wrenches without slipping. It is commonly used by electrical and controls technicians during panel builds, control board replacements, and OEM-style equipment assemblies in both residential and light commercial applications.

Key Features

• Male-female thread configuration: 8-32 male post, 8-32 female threaded bore for stackable mounting
• Overall length of 1.375 inches with a 1-inch body length and 1/4-inch width across flats
• Grade 2 steel construction with zinc-plated finish meeting ASTM B633 Type 1 and QQ-S-633
• Hex body shape accepts standard nut drivers and wrenches for secure installation
• Thread depth of 7/16 inch on the female end for full thread engagement
• Length tolerance of -0.005 to 0.005 inch for consistent stack height across assemblies

Compatibility

Designed as an OEM-style 8-32 male-female hex standoff for use in circuit board mounting applications requiring a 1.375-inch standoff height in inch-measurement assemblies.

Installation Notes

Installation is typically performed by electricians or controls technicians during panel assembly or circuit board service. De-energize all equipment and discharge any stored energy before working inside control cabinets or on PCB assemblies. A nut driver or open-end wrench sized to 1/4-inch flats is recommended for torque-controlled tightening. Avoid over-tightening, which can strip the 8-32 threads or crack the circuit board mounting hole.
