Electro Hardware MMF1317M06F16M3 Hex Standoff M3x0.5

Product Description

The ELECTRO HARDWARE MMF1317M06F16M3 is an aluminum male-female hex circuit board standoff designed to create precise spacing between PCBs and mounting surfaces in electronic assemblies. Machined from aluminum alloy T3 material and left uncoated with a bright finish, this standoff meets QQ-A-225A Comp 2 material standards. The hex body measures 4.5 mm across flats, providing a positive grip surface for installation with a standard nut driver or wrench. With an overall length of 17.76 mm, a body length of 13.00 mm, and an M3 x 0.5 thread on both the male and female ends, it delivers consistent, repeatable stack height across multi-board assemblies. Electronics technicians and PCB assembly professionals are the primary installers.

This standoff is suited for use in control board assemblies, instrumentation enclosures, and electronic equipment where secure, adjustable board-to-board or board-to-chassis spacing is required. The metric M3 x 0.5 thread size is common in compact electronic assemblies found in HVAC control systems, industrial controls, and similar equipment. The male end threads into a receiving female standoff or threaded hole while the female end accepts the fastener securing the next board in the stack.

Compatibility

Designed as a standard M3 x 0.5 metric hex standoff for use in PCB and circuit board assemblies requiring male-female stacking hardware.

Installation Notes

Install and remove standoffs using an appropriately sized nut driver or hex wrench to avoid rounding the hex flats. De-energize all circuits and discharge any stored energy in the assembly before handling circuit boards or mounting hardware. Avoid over-torquing aluminum standoffs, as the material is softer than steel and thread damage can occur with excessive force. Follow applicable assembly documentation and IPC standards for PCB hardware installation.
