Electro Hardware P513M10F21-832 Round Female Standoff

Product Description

The ELECTRO HARDWARE P513M10F21-832 is a round female standoff designed to create fixed spacing between two mating components in panel, enclosure, and circuit board assemblies. Machined from Grade 2 steel with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-S-633 standards, this standoff is fully threaded with an 8-32 thread size. The overall length is 0.25 inches, the outside diameter is 0.25 inches, and the thread depth runs 1 inch. It is installed by electricians, electronics technicians, and mechanical assemblers working on control panels, electrical enclosures, and rack-mounted equipment.

This standoff is suited for light-duty fastening applications where a female-threaded receiver is needed to accept a machine screw from both ends or from one end in a through-bolt configuration. Typical use cases include PCB mounting, DIN rail enclosure assembly, and instrument panel fabrication in residential, commercial, and light industrial electrical work. The inch-system dimensions and standard 8-32 thread make it compatible with common imperial fastener hardware used across the electrical and electronics trades.

Key Features

• Fully threaded female interior accepts 8-32 machine screws
• Zinc-plated steel finish meets ASTM B633 Type 1 and QQ-S-633 corrosion resistance standards
• Round body shape with 0.25 inch outside diameter fits standard standoff mounting patterns
• Grade 2 steel construction provides adequate tensile strength for light panel assembly applications
• Length tolerance of -0.005 to 0.005 inches supports precise spacing in stacked assemblies
• Compact 0.25 inch overall length suited for tight enclosure and PCB stack applications

Compatibility

Designed as an OEM-style replacement or standard hardware component for use with 8-32 machine screws in inch-system panel and enclosure assemblies.

Installation Notes

Installation is typically performed by electricians or electronics technicians during panel build or enclosure assembly. De-energize all equipment before working inside electrical enclosures per NFPA 70E safe work practices. Use a properly sized hex key, socket, or nut driver matched to the standoff body to avoid deforming the zinc-plated finish. Do not over-torque threaded fasteners into the female standoff, as Grade 2 steel threads can strip under excessive load.
