Electro Hardware P513M06F16-440 Hex Board Standoff 4-40

Product Description

The ELECTRO HARDWARE P513M06F16-440 is a female hex circuit board standoff machined from aluminum alloy grade T3 with an anodized finish. It is designed to create precise spacing between a printed circuit board and a chassis, panel, or secondary board in electronic assemblies. The standoff accepts a 4-40 threaded fastener, has an overall length of 0.25 inches, and a hex body width across flats of 0.25 inches. The hex body shape allows installation and removal with standard hex drivers or wrenches. This hardware is commonly installed by electronics assemblers, field service technicians, and HVAC or controls technicians working with control board assemblies.

This standoff is suited for use in light-duty electronic enclosures, control panels, and circuit board mounting applications where aluminum hardware is preferred for its corrosion resistance and light weight. The anodized finish provides additional surface protection. The 4-40 thread size is a standard inch-series thread widely used in PCB and instrument panel assemblies across residential and commercial electronic equipment, including control board stacks in HVAC and building automation systems.

Key Features

• Aluminum T3 alloy construction with anodized bright finish for corrosion resistance
• Meets QQ-A-225A Comp 2 fastener standard

Compatibility

Designed as an OEM-style replacement or standard-fit standoff for circuit board mounting applications using 4-40 inch-series threaded fasteners.

Installation Notes

Installation is performed by electronics or controls technicians. Power down and de-energize all equipment before servicing circuit board assemblies. Use an appropriately sized hex driver or nut driver matching the 0.25-inch width across flats to avoid stripping the hex body. Do not overtighten, as aluminum threads can be damaged by excessive torque.
