Electro Hardware MMF1825M09F16M4 Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MMF1825M09F16M4 is a male-female hex circuit board standoff designed to create precise spacing between PCBs and mounting surfaces in electronic assemblies. Machined from 303 stainless steel with a bright uncoated finish, this standoff meets the QQ-S-763 fastener standard. The M4 x 0.7 thread size is common in metric electronic and industrial applications. The overall length is 26.53 mm, with a hex body length of 17.00 mm and a 6.00 mm width across flats. Licensed electronics assembly technicians and industrial maintenance electricians typically install these fasteners during PCB mounting and chassis assembly work.

This standoff is suited for metric PCB stackup applications in control panels, industrial electronics enclosures, and equipment requiring precise board-to-board or board-to-chassis spacing. The male thread end engages a threaded mounting hole or nut while the female threaded end accepts a screw from the board above, making it practical for multi-board assemblies. It is commonly used in HVAC control boards, electrical equipment chassis, and similar light-duty electronic hardware installations where corrosion resistance and dimensional consistency are required.

Key Features

• M4 x 0.7 metric thread on both male and female ends for standard metric PCB mounting
• 303 stainless steel construction meets QQ-S-763 fastener standard for corrosion resistance
• Hex body shape with 6.00 mm width across flats allows wrench or socket tightening
• Overall length of 26.53 mm with 9.53 mm thread length and 11.10 mm female thread depth
• Length tolerance of -0.150 to 0.150 mm for consistent stackup dimensions
• Bright uncoated finish maintains dimensional accuracy without added coating buildup

Compatibility

Designed as an OEM-style metric hex standoff for circuit board assemblies using M4 x 0.7 threaded mounting points in control panels, industrial enclosures, and electronic equipment chassis.

Installation Notes

Power down all equipment completely before servicing PCB mounting hardware. Use an appropriately sized wrench or socket matching the 6.00 mm width across flats to seat the standoff without over-torquing the stainless steel threads. Ensure mating threads are clean and free of debris before assembly. Follow applicable electrical safety codes and equipment manufacturer guidelines when working inside control enclosures.
