Electro Hardware P577M10F21-832 Round Female Standoff

Product Description

The ELECTRO HARDWARE P577M10F21-832 is a round female standoff designed for use in panel assemblies, enclosures, and electronic equipment mounting applications. Machined from Grade 2 steel with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-S-633 standards, this standoff provides a fully threaded internal bore sized for 8-32 fasteners. Overall length is 1.25 inches with an outside diameter of 0.25 inches and a full 1 inch of usable thread depth. The zinc plating delivers corrosion resistance suitable for indoor industrial and electrical enclosure environments. Electricians, panel builders, and equipment fabricators install these standoffs when spacing circuit boards, brackets, or sub-panels away from a mounting surface.

This standoff is used in residential and commercial electrical panel construction, control cabinet assembly, and electronic equipment fabrication. The 8-32 thread size is common in instrument panels, HVAC control boards, and low-voltage electrical enclosures. Its compact 0.25 inch outside diameter and 1.25 inch body length make it suited for tight spacing situations where a reliable threaded post is needed without added bulk. Typical installers include electricians, controls technicians, and panel fabricators working with standard inch-measurement hardware.

Key Features

• Fully threaded internal bore accepts 8-32 fasteners along the full 1 inch thread depth
• Overall length of 1.25 inches with a 0.25 inch outside diameter for compact panel layouts
• Grade 2 steel construction provides reliable mechanical strength for enclosure and panel applications
• Zinc-plated finish meets ASTM B633 Type 1 and QQ-S-633 for corrosion resistance in indoor environments
• Length tolerance held to -0.005 to 0.005 inches for consistent stacking and spacing
• Round body shape allows installation with standard hex or spanner tooling

Compatibility

Designed as a standard inch-measurement female standoff compatible with 8-32 threaded fasteners in panel assemblies, control enclosures, and electronic equipment mounting applications requiring a 1.25 inch OAL round standoff.

Installation Notes

Installation is typically performed by electricians or controls technicians during panel or enclosure assembly. De-energize all equipment before working inside any enclosure. Use appropriately sized hex or spanner tools to achieve firm seating without over-torquing the threaded bore. Follow applicable NEC guidelines for enclosure assembly and hardware fastening practices.
