Electro Hardware P545M10F21-632 Round Female Standoff

Product Description

The ELECTRO HARDWARE P545M10F21-632 is a round female standoff designed to create fixed spacing between panels, PCBs, enclosures, and structural members in threaded fastener assemblies. It features a 6-32 thread size with a fully threaded interior, an overall length of 0.75 inches, and an outside diameter of 0.25 inches. The body is steel with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-S-633 standards, providing corrosion resistance suitable for general industrial and electronic assembly applications. This standoff is installed by electricians, electronics technicians, and mechanical assemblers working on panel builds, control enclosures, and equipment chassis.

This standoff is suited for use in residential and commercial control panels, electronic enclosures, HVAC control boards, and light-duty structural spacer applications where a fully threaded female receptacle is required. The inch-system dimensions and 6-32 thread make it compatible with standard machine screw assemblies commonly found in electrical and electronic equipment. Its compact 0.25-inch OD allows use in tight-clearance layouts where larger standoffs will not fit.

Key Features

• Fully threaded female interior accepts 6-32 machine screws from both ends
• Overall length of 0.75 inches with a length tolerance of -0.005 to 0.005 inches
• Outside diameter of 0.25 inches for use in close-clearance assemblies
• Steel construction with zinc-plated finish per ASTM B633 Type 1 and QQ-S-633
• Round body shape, Grade 2 material grade, inch measurement system

Compatibility

Designed as an OEM-style replacement or new-installation standoff for assemblies using 6-32 inch-series threaded fasteners in panel, enclosure, and PCB mounting applications.

Installation Notes

Installation is performed by electricians, electronics technicians, or mechanical assemblers. Ensure mating screws are 6-32 thread form and appropriate length for the application before installation. Use proper hand tools or a torque driver set to the assembly specification for the mating hardware. Inspect the zinc-plated finish for damage before installation in environments where corrosion resistance is critical.
