Electro Hardware MMF1835M09F16M4 Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MMF1835M09F16M4 is a male-female hex circuit board standoff designed to create precise spacing between PCBs, panels, or chassis layers in electronic assemblies. Machined from 303 stainless steel with a bright uncoated finish, this standoff meets the QQ-S-763 fastener standard for corrosion resistance and dimensional consistency. The M4x0.7 thread runs on both the male pin end and the female threaded bore, allowing boards to be stacked or mounted securely with standard M4 hardware. The hex body measures 6 mm across flats, accepting a standard hex driver or nut driver for installation without slippage. Electronics assemblers, field service technicians, and industrial maintenance personnel typically install these in control panels, HVAC circuit board assemblies, and industrial enclosures.

This standoff is suited for metric-threaded PCB mounting applications in both residential and commercial equipment. It provides a rigid, reusable mechanical connection wherever a threaded male post and a receiving female thread are needed in a single fastener. Typical install scenarios include control board mounting in HVAC units, variable-frequency drive enclosures, and general electronics panel builds where board-to-board or board-to-chassis standoff spacing is required.

Key Features

• 303 stainless steel construction with QQ-S-763 compliance for corrosion resistance
• M4x0.7 male-female thread configuration for stackable PCB mounting
• Hex body profile at 6 mm across flats allows positive wrench engagement
• Overall length of 31.53 mm with a 22.00 mm body length and 9.53 mm thread length
• Length tolerance of -0.150 to 0.150 mm for dimensional accuracy
• Bright uncoated finish maintains conductivity where grounding continuity matters

Compatibility

Designed as a metric M4x0.7 hex standoff for use in any application requiring a male-to-female PCB or panel standoff connection with standard M4 metric hardware.

Installation Notes

Installation is performed with a hex driver or nut driver sized for a 6 mm across-flats hex body. Power down and de-energize all equipment before working inside control panels or electronics enclosures. Thread engagement should be firm and snug without over-torquing, as stainless fasteners are susceptible to galling if driven too aggressively. Follow applicable assembly documentation and any relevant enclosure or panel standards for the equipment being serviced.
