Electro Hardware MMF1831M09F16M4 Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MMF1831M09F16M4 is a male-female hex circuit board standoff designed to create precise spacing and secure mounting between PCBs, enclosures, and panels. Machined from 303 stainless steel with a bright uncoated finish, this standoff meets the QQ-S-763 fastener standard for stainless steel hardware. It features an M4 x 0.7 thread size on both the male and female ends, a 6 mm width across flats for standard hex tooling, and an overall length of 29.53 mm (approximately 1.163 inches). Electronics assemblers, electrical panel builders, and control board technicians install these standoffs where corrosion resistance and dimensional consistency are required.

This standoff is suited for use in electronic enclosures, industrial control panels, HVAC control boards, and similar applications where PCBs must be mounted at a fixed, repeatable distance from a substrate or second board. The hex body geometry allows installation and removal with standard hex drivers or wrenches without slipping. Its metric M4 x 0.7 thread profile makes it appropriate for metric-spec assemblies across residential and commercial electronic equipment. Minimum order quantity is 10 pieces; each package contains 1 piece.

Key Features

• M4 x 0.7 male-female thread configuration for through-board standoff mounting
• 303 stainless steel construction rated to QQ-S-763 standard for corrosion resistance
• 6 mm width across flats accepts standard metric hex tooling
• Overall length of 29.53 mm with body length of 20.00 mm and thread length of 9.53 mm
• Length tolerance of -0.150 mm to +0.150 mm for consistent stack height
• Bright uncoated finish - no plating buildup to affect thread engagement

Compatibility

Designed as an OEM-style metric standoff for M4 x 0.7 threaded assemblies including circuit board mounting applications in electronic enclosures and control panels.

Installation Notes

Installation is performed by electronics assemblers or licensed electricians working on panel and board assemblies. Power down and de-energize all equipment before installing or removing standoffs from live circuit boards or control panels. Use a hex driver or wrench sized to 6 mm across flats to prevent rounding the hex body. Avoid over-torquing, which can crack PCB mounting holes or damage threaded inserts in the mating board.
