Electro Hardware P561M12F21-832 Female Hex Standoff 8-32

Product Description

The ELECTRO HARDWARE P561M12F21-832 is a female hex circuit board standoff designed to create precise spacing and secure mounting between circuit boards and chassis surfaces in electronic assemblies. Manufactured from Grade 2 steel with a zinc-plated clear chromate finish meeting ASTM B633 Type 1 and QQ-S-633 standards, this standoff provides corrosion resistance and reliable mechanical performance. It features an 8-32 female thread, a hex body profile measuring 1/4 inch across flats, and an overall length of 1 inch. Electricians, electronics technicians, and panel builders rely on this hardware when assembling control panels, relay boards, and similar low-voltage electronic enclosures.

This standoff is suited for use in residential and commercial electronic assemblies where PCB-to-chassis or board-to-board spacing must be maintained with consistent, repeatable standoff heights. Typical applications include control board mounting inside HVAC equipment, electrical panel enclosures, and industrial electronics. The female thread design accepts a machine screw from the mating component, simplifying stack assembly during installation or board replacement service calls.

Key Features

• Female 8-32 thread accepts standard machine screws for secure board mounting
• Hex body profile allows wrench engagement for precise installation torque control
• 1 inch overall body length provides consistent PCB standoff height
• Grade 2 steel construction for reliable mechanical strength in panel environments
• Zinc-plated clear chromate finish meets ASTM B633 Type 1 and QQ-S-633 corrosion resistance standards
• Length tolerance of -0.005 to +0.005 inches ensures dimensional consistency across assemblies

Compatibility

Designed as an OEM-style replacement or stock hardware component for circuit board mounting applications requiring an 8-32 female hex standoff with a 1-inch overall length and 1/4-inch hex body width.

Installation Notes

Installation is typically performed by electricians or electronics technicians during control board assembly or replacement service. Power down and de-energize the equipment fully before handling any circuit board mounting hardware. Use an appropriately sized hex wrench or nut driver on the hex body to seat the standoff without overtightening, which can crack board substrates or strip threads. Follow applicable NEC and equipment manufacturer guidelines when working inside electrical enclosures.
