Electro Hardware P577M10F21-1032 Round Female Standoff

Product Description

The ELECTRO HARDWARE P577M10F21-1032 is a round female standoff designed for use in panel assemblies, electronic enclosures, and structural fastening applications where precise spacing and thread engagement are required. Manufactured from Grade 2 steel with a zinc-plated finish that meets ASTM B633 Type 1 and QQ-S-633 standards, this standoff delivers reliable corrosion resistance in typical indoor environments. It features a 10-32 female thread, a 1.25-inch overall length, a 0.25-inch outside diameter, and a full 1-inch thread depth throughout the body. Electricians, panel builders, and mechanical assembly technicians commonly install this type of hardware in control panels, PCB mounts, and equipment enclosures.

This standoff is suited for light industrial, commercial, and residential panel fabrication work. The fully threaded interior accommodates a 10-32 fastener along the entire 1-inch thread depth, allowing consistent thread engagement for secure, repeatable assemblies. The round body profile and compact 0.25-inch outside diameter make it a practical choice in tight clearance layouts where space between mounting surfaces is limited. It is sold and packaged as a single unit.

Key Features

• 10-32 female thread, fully threaded to 1-inch depth for maximum fastener engagement
• 1.25-inch overall length provides consistent panel spacing
• 0.25-inch outside diameter suits tight clearance mounting layouts
• Grade 2 steel construction for reliable mechanical strength
• Zinc-plated finish meets ASTM B633 Type 1 and QQ-S-633 corrosion resistance standards
• Round body profile for straightforward installation with standard hex or socket tools

Compatibility

Designed as an OEM-style replacement or new-installation standoff for applications requiring a 10-32 female-threaded round steel standoff with a 1.25-inch overall length and 0.25-inch outside diameter.

Installation Notes

Installation is performed by mechanical assembly technicians or electricians during panel or enclosure fabrication. Power down and de-energize all equipment before installing or removing standoffs in live panels. Use the appropriate torque driver or hex tool sized to the 0.25-inch outside diameter body to avoid deforming the standoff. Do not over-torque mating fasteners, as the Grade 2 steel thread may be damaged by excessive force beyond design specifications.
