Electro Hardware P577M04F16-832 Round Female Standoff

Product Description

The ELECTRO HARDWARE P577M04F16-832 is a round female standoff designed for use in panel assemblies, electronic enclosures, and structural spacer applications. This fully threaded aluminum standoff accepts an 8-32 thread, measures 1.25 inches in overall length, and features a 0.25-inch outside diameter with a 1-inch thread depth. Machined from aluminum alloy to material grade T-3 and finished bright anodized per QQ-A-225A Comp 2, this standoff delivers corrosion resistance and dimensional consistency. Electricians, panel builders, and electronics assembly technicians install this type of hardware when precise board-to-chassis or board-to-board spacing is required.

This standoff is suited for residential and commercial electrical panel fabrication, electronic control board mounting, and instrumentation enclosures where a female-threaded spacer is needed to accept a machine screw from one or both ends. The inch-system dimensions and 8-32 thread make it a common fit in standard North American panel and PCB assembly workflows. The bright anodized finish is appropriate for environments where mild corrosion resistance and a clean appearance are required.

Key Features

• 8-32 female thread with 1-inch full thread depth for secure fastener engagement
• 1.25-inch overall length and 0.25-inch outside diameter for compact spacing applications
• Aluminum construction, material grade T-3, for lightweight strength
• Bright anodized finish meets QQ-A-225A Comp 2 standard
• Length tolerance held to -0.005 to 0.005 inches for precise stack-up control
• Round body shape with inch-system dimensions for standard North American hardware compatibility

Compatibility

Designed as a standard-fit female standoff for electronic enclosures, control panels, and PCB mounting applications requiring an 8-32 thread in an inch-system round body configuration.

Installation Notes

Installation is typically performed by electricians or electronics assembly technicians using a hex driver or wrench sized to the standoff body. Power down and de-energize all circuits before installing or removing standoffs in live panels or enclosures. Avoid over-torquing aluminum standoffs, as the material is softer than steel and the threads can strip under excessive force. Follow applicable NEC guidelines when mounting hardware inside electrical enclosures.
