Electro Hardware P577M03F21-1032 Hex Standoff 10-32

Product Description

The ELECTRO HARDWARE P577M03F21-1032 is a female hex circuit board standoff designed to mount and space printed circuit boards within electronic enclosures and control assemblies. Machined from brass with a zinc-plated clear chromate finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff provides reliable corrosion resistance and secure thread engagement. The hex body measures 0.25 inches across flats, allowing installation and removal with standard hex tooling. Overall length is 1.25 inches with a tight length tolerance of -0.005 to 0.005 inches. Electricians, control panel builders, and electronics technicians use this fastener when stacking or isolating PCBs in HVAC controls, automation panels, and similar assemblies.

This standoff is suited for residential and light commercial control board assemblies, industrial enclosures, and any application requiring a threaded female-to-female or male-to-female board mounting solution. The 10-32 thread size is a common standard in electronic and instrumentation hardware, making this part a straightforward drop-in for panel builds and board replacements where a 1.25-inch standoff height is required. It is sold individually, making it practical for single-unit repairs and small-quantity builds.

Key Features

• Female hex body with 10-32 thread for secure PCB mounting
• Brass construction with zinc-plated clear chromate finish for corrosion resistance
• Overall length of 1.25 inches with tight tolerance of plus or minus 0.005 inches
• 0.25-inch width across flats for standard hex driver or wrench installation
• Meets ASTM B633 Type 1 and QQ-B-626 Comp 22 fastener standards
• Hex body shape allows positive grip and torque without slipping

Compatibility

Designed as a standard 10-32 female hex circuit board standoff suitable for PCB mounting applications requiring a 1.25-inch overall length and a 0.25-inch hex profile.

Installation Notes

Power down and de-energize all control panels or enclosures before installing or replacing standoffs. Use a properly sized hex driver or open-end wrench matched to the 0.25-inch across-flats dimension to avoid rounding the hex body. Follow applicable NEC guidelines when working inside electrical enclosures. Do not overtighten, as brass threads can be damaged by excessive torque.
