Electro Hardware P513M12F21-832 Hex Standoff 8-32 1/4 in

Product Description

The ELECTRO HARDWARE P513M12F21-832 is a female hex circuit board standoff designed to create consistent spacing between PCBs and mounting surfaces in electronic assemblies. Machined 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 in light-duty environments. The hex body shape allows standard wrench installation and removal without slippage. With an overall length of 0.25 inches and a width across flats of 0.25 inches, it is suited for compact board-mounting applications where precise, repeatable standoff height is required.

This standoff is used in residential and commercial electronic panel assemblies, control boards, and enclosure-mounted PCBs across HVAC controls, electrical panels, and industrial equipment. It accepts 8-32 threaded fasteners and is installed where boards must be elevated from a chassis or secondary PCB to allow airflow, prevent shorts, or provide a secure mechanical attachment point. Electricians, control-board technicians, and electronics assembly professionals typically install this component.

Key Features

• Female 8-32 thread accepts standard machine screws for secure board mounting
• Hex body shape allows wrench engagement for controlled torque application
• Grade 2 steel construction provides reliable mechanical strength for PCB support
• Zinc-plated clear chromate finish meets ASTM B633 Type 1 and QQ-S-633 standards
• Compact 0.25 inch overall length suited for tight board-to-surface spacing

Compatibility

Designed as an OEM-style replacement or new-installation standoff for circuit boards and electronic assemblies using 8-32 threaded fastener systems.

Installation Notes

Installation is typically performed by licensed electricians or electronics technicians. Always de-energize the assembly and discharge any stored capacitance before mounting or removing circuit boards. Use a wrench or hex driver sized to the 0.25 inch width across flats to seat the standoff without damaging the board or chassis. Follow applicable NEC guidelines when working inside electrical enclosures.
