Electro Hardware MP447M09F16M3 Female Hex Standoff M3

Product Description

The ELECTRO HARDWARE MP447M09F16M3 is a female hex circuit board standoff designed to create precise spacing between PCBs and mounting surfaces in electronic assemblies. Manufactured from 303 stainless steel with a plain, bright uncoated finish, this standoff accepts an M3 x 0.5 threaded fastener and provides a 6.4 mm thread engagement depth. The overall length is 24.0 mm, and the hex body measures 4.5 mm across the flats, allowing standard hex tooling for secure installation. It is partially threaded and meets the QQ-S-763 stainless steel fastener standard. Electronics assemblers, PCB technicians, and industrial equipment builders commonly install this hardware.

This standoff is suited for metric-threaded circuit board mounting applications in electronics manufacturing, control panel assembly, and industrial equipment builds. It is used wherever a female-threaded hex spacer is required to stack or offset printed circuit boards at a fixed distance from a chassis or base plate. The M3 x 0.5 thread pitch is standard across a wide range of PCB hardware and metric fastener systems, making this standoff broadly applicable in both commercial and industrial electronic assembly work.

Key Features

• Female M3 x 0.5 thread accepts standard metric M3 screws
• 24.0 mm overall length provides consistent board-to-board or board-to-chassis spacing
• 4.5 mm hex body width allows installation and removal with standard hex drivers or wrenches
• 6.4 mm thread depth provides secure fastener engagement
• 303 stainless steel construction resists corrosion in demanding environments
• Meets QQ-S-763 stainless steel fastener standard

Compatibility

Designed for use in metric M3 x 0.5 threaded circuit board mounting applications as a standard female hex spacer in PCB assembly and electronic enclosure builds.

Installation Notes

Install using a hex driver or wrench sized to 4.5 mm across the flats. Power down and de-energize all equipment before servicing or assembling circuit board hardware. Avoid over-torquing, as stainless steel fasteners are susceptible to galling; apply appropriate anti-seize if reuse is anticipated. Note the minimum order quantity of 10 units.
