Electro Hardware MMX1702M09-MSC M4 Hex Standoff Stainless

Product Description

The ELECTRO HARDWARE MMX1702M09-MSC is a male-male hex circuit board standoff designed for metric fastening applications in electronic assemblies. Threaded M4 x 0.7 on both ends, this standoff provides a rigid, conductive spacer between PCBs, panels, or mounting surfaces. It is machined from Grade 18-8 / 303 stainless steel with a passivated finish that meets QQ-S-763 standards, offering corrosion resistance in demanding environments. The overall length is 3.5 mm, the body is hex-shaped at 10 mm width across flats for wrench engagement, and thread length ranges from 8.5 mm to 9.5 mm. Electronics technicians, electrical engineers, and production assemblers typically install this hardware during board-level builds or panel assembly work.

This standoff is suited for metric PCB mounting applications requiring a double-male threaded fastener with a hex body. The hex profile allows precise torque application with a standard wrench or nut driver, making it appropriate for both prototype and production environments. Its stainless steel construction makes it a reliable choice in applications where mild chemical exposure or moisture is a concern, such as industrial control panels, electrical enclosures, and electronic test fixtures.

Key Features

• M4 x 0.7 male threads on both ends for double-sided fastening
• Hex body at 10 mm width across flats for wrench-driven installation
• Grade 18-8 / 303 stainless steel construction with passivated finish
• Meets QQ-S-763 fastener standard
• 3.5 mm overall body length with thread lengths of 8.5 mm, 9 mm, and 9.5 mm
• Length tolerance of -0.15 mm to +0.15 mm for consistent fit

Compatibility

Designed as an OEM-style metric standoff for circuit board and panel assemblies requiring M4 x 0.7 male-male threaded hardware with a hex drive profile.

Installation Notes

Installation is typically performed by electronics technicians or electrical assemblers using a standard wrench or nut driver sized to the 10 mm hex. Ensure mating threads are clean and free of debris before assembly. Do not overtighten, as stainless steel fasteners are susceptible to galling if driven without appropriate lubrication or care. Power down and discharge any circuit boards before handling to prevent electrostatic damage or injury.
