Electro Hardware P561M01F21-832 Female Standoff 8-32

Product Description

The ELECTRO HARDWARE P561M01F21-832 is a round female standoff designed to create threaded spacers between panels, boards, or structural components in electrical enclosures, control panels, and electronic assemblies. This standoff measures 1 inch overall length with a 1/4 inch outside diameter and is fully threaded to a depth of 1 inch, accepting an 8-32 thread. Constructed from brass with a zinc-plated finish that meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, it provides corrosion resistance and reliable thread engagement in fixed-spacing applications.

This standoff suits residential and commercial panel builds, electronic enclosures, and instrumentation mounting where precise board-to-board or board-to-chassis spacing is required. Electricians, panel builders, and electronics technicians commonly install these in control cabinets, junction boxes, and printed circuit board assemblies. The round body shape and standard inch-measurement system make it a straightforward fit in typical North American fabrication and assembly workflows.

Key Features

• Fully threaded female interior accepts 8-32 fasteners through the full 1 inch thread depth
• Brass construction provides good electrical conductivity and machinability
• Zinc-plated finish meets ASTM B633 Type 1 and QQ-B-626 Comp 22 for corrosion resistance
• Compact 1/4 inch outside diameter fits tight panel layouts
• Length tolerance held to -0.005 to 0.005 inches for consistent stack-up in multi-standoff assemblies
• Round body shape allows installation with standard hex or pin-spanner tooling

Compatibility

Designed as an OEM-style female standoff for use in electrical panels, electronic enclosures, and control assemblies requiring an 8-32 threaded brass spacer with a 1/4 inch outside diameter and 1 inch overall length.

Installation Notes

Installation is typically performed by electricians or panel assembly technicians using standard hand tools. De-energize and lock out the panel or enclosure before installing or removing standoffs in live assemblies. Use the correct driver or wrench size to avoid deforming the brass body; do not over-torque, as brass threads can strip under excessive force. Verify thread engagement depth against mating fastener length before final assembly to ensure secure, flush mounting.
