Electro Hardware P505M10F21-1032 Female Standoff 10-32

Product Description

The ELECTRO HARDWARE P505M10F21-1032 is a round female standoff designed for use in panel fabrication, electronics enclosures, and mechanical assemblies where a threaded female receptacle is needed at a fixed spacing. It accepts a 10-32 thread and is fully threaded through its 0.125-inch overall length, with an outside diameter of 0.25 inches. Constructed from Grade 2 steel with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-S-633 standards, it provides corrosion resistance in typical indoor industrial and commercial environments. This fastener is installed by electricians, panel builders, and mechanical assemblers working with standard inch-series hardware.

This standoff is suited for light-duty fixed-spacing applications in electrical enclosures, control panels, PCB mounting, and general sheet-metal assemblies. Its compact 0.125-inch body length makes it appropriate where minimal standoff height is required between mating surfaces. The zinc-plated steel construction fits standard commercial and industrial fabrication environments. It is sold individually, making it practical for maintenance, repair, and small-quantity build applications.

Key Features

• 10-32 female thread, fully threaded through the body
• 0.125-inch overall length for minimal-profile standoff spacing
• 0.25-inch outside diameter, round body shape
• Grade 2 steel construction with zinc-plated finish
• Meets ASTM B633 Type 1 and QQ-S-633 finish standards
• Length tolerance of -0.005 to 0.005 inches for consistent fitment

Compatibility

Designed as a standard inch-series female standoff compatible with 10-32 threaded fasteners in electrical enclosures, control panels, and mechanical assemblies requiring a 0.125-inch standoff height.

Installation Notes

Install using a hex driver or appropriate socket sized to the 0.25-inch outside diameter body. Ensure mating screws are the correct 10-32 thread pitch before assembly to avoid cross-threading. Power down any electrical enclosure fully before installing or removing standoffs in live panel environments. Torque to the assembly specification defined by the panel or enclosure manufacturer.
