Electro Hardware 1443M03F21-832 Hex Standoff 8-32

Product Description

The ELECTRO HARDWARE 1443M03F21-832 is a male-female hex circuit board standoff designed to create a fixed, threaded spacer between a PCB and a mounting surface or between stacked boards. The standoff features an 8-32 thread size with a male thread on one end and a female thread on the other, allowing boards to be secured and layered at a consistent, stable interval. The hex body profile measures 1/4 inch across flats, providing a wrench or driver engagement point during installation. Manufactured from brass with a zinc-plated finish that meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff is suited for environments where corrosion resistance and reliable conductivity are required.

This standoff is used in control board assemblies, electronic enclosures, and industrial panel builds where a threaded spacer is needed to mount or stack PCBs at a fixed height. The 1-1/8-inch overall length with a 3/4-inch hex body and 3/8-inch male thread makes it appropriate for applications requiring moderate board clearance. It is commonly installed by electronics technicians, HVAC controls specialists, and industrial electricians during panel assembly or control board replacement work.

Key Features

• Male-female thread configuration allows stacking or surface mounting of circuit boards at a fixed standoff height
• 8-32 thread size with 3/8-inch male thread length and 7/16-inch female thread depth
• Hex body shape with 1/4-inch width across flats for wrench engagement and secure torquing
• Brass construction with zinc-plated finish meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards
• Overall length of 1-1/8 inches with a 3/4-inch body length provides consistent board clearance
• Length tolerance of -0.005 to +0.005 inches ensures precise, repeatable fitment

Compatibility

Designed as a standard 8-32 male-female hex standoff for use in circuit board mounting applications requiring a 1-1/8-inch overall length brass spacer with zinc-plated finish.

Installation Notes

Installation is typically performed by electronics technicians or licensed electricians working on control panels and PCB assemblies. Power down and de-energize all circuits completely before removing or installing standoffs in any live panel or control board assembly. Use an appropriately sized hex wrench or nut driver on the hex body to avoid rounding the flats. Follow applicable NEC guidelines and equipment manufacturer specifications for PCB mounting hardware when servicing electrical enclosures.
