Electro Hardware P561M04F16-632 Round Female Standoff

Product Description

The ELECTRO HARDWARE P561M04F16-632 is a round female standoff designed to create fixed spacing between circuit boards, panels, and other structural components in electronic and electrical assemblies. This standoff features a 6-32 thread size with a 1 inch overall length and a 0.25 inch outside diameter. The body is fully threaded along the entire 1 inch thread depth, allowing a fastener to engage from either end or at any point along the interior. Machined from aluminum to the T-3 material grade, it carries a bright anodized finish and conforms to QQ-A-225A Comp 2 specifications. Licensed electricians, panel builders, and electronics assembly technicians typically install these standoffs in enclosure and PCB mounting applications.

This standoff is suited for use in electronic control panels, printed circuit board assemblies, electrical enclosures, and instrument mounting applications where a precise, fixed offset is required. The aluminum construction keeps weight low while providing adequate strength for light- to medium-duty fastening tasks. The bright anodized finish provides a degree of corrosion resistance appropriate for indoor panel environments. Minimum order quantity is 25 pieces, and the part is sold in individual unit packaging.

Key Features

• Fully threaded female interior along the full 1 inch body length for maximum fastener engagement flexibility
• 6-32 thread size compatible with standard machine screws commonly used in electronics and panel assembly
• Aluminum construction with T-3 material grade for a lightweight, corrosion-resistant standoff
• Bright anodized finish meets QQ-A-225A Comp 2 fastener standard
• Round body shape with 0.25 inch outside diameter fits tight board layouts
• Length tolerance held to -0.005 to 0.005 inches for consistent stack height in multi-board assemblies

Compatibility

Designed as an OEM-style replacement or new-installation standoff for electronic enclosures, PCB assemblies, and panel mounting applications requiring a 6-32 female threaded aluminum standoff with 1 inch overall length.

Installation Notes

Installation is typically performed by electricians or electronics assembly technicians during panel build or board mounting. Power down and de-energize any assembly before installing or removing standoffs in live enclosures. Use the appropriate 6-32 machine screws and a proper-fitting driver or nut driver to avoid stripping the anodized aluminum threads. Follow applicable NEC guidelines when mounting standoffs inside electrical enclosures.
