Electro Hardware MMF1833M09F16M4 Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MMF1833M09F16M4 is a male-female hex circuit board standoff designed to create precise spacing and secure mechanical connections between PCBs, panels, and enclosures. Machined from 303 stainless steel with a bright uncoated finish, this standoff meets the QQ-S-763 fastener standard. It features an M4 x 0.7 thread on both ends and a hexagonal body with a 6 mm width across flats, making it easy to torque with standard hex tooling. The overall length is 30.53 mm with a body length of 21.00 mm and a thread length of 9.53 mm on the male end and 11.10 mm thread depth on the female end. Electronics assembly technicians and panel builders install these standoffs in control boards, enclosures, and industrial equipment.

This standoff is suited for metric-threaded circuit board mounting applications in industrial control panels, HVAC control board assemblies, electrical enclosures, and similar equipment where corrosion resistance and dimensional precision are required. The stainless steel construction makes it appropriate for environments where carbon steel hardware would be prone to oxidation. It is sold individually but carries a minimum order quantity of 10 units, making it practical for both service bench stock and volume assembly work.

Key Features

• M4 x 0.7 metric thread on both male and female ends for standard metric PCB mounting
• 303 stainless steel construction with bright uncoated finish for corrosion resistance
• Hex body at 6 mm width across flats allows torquing with standard hex wrenches or nut drivers
• Overall length of 30.53 mm with a length tolerance of -0.150 to 0.150 mm for precise stack height control
• Meets QQ-S-763 fastener standard
• UNSPSC Code 31161816 for streamlined procurement classification

Compatibility

Designed for use in M4 x 0.7 metric-threaded circuit board and panel mounting applications requiring a hex male-female standoff configuration.

Installation Notes

Installation is typically performed by electronics assembly technicians or panel builders using a hex wrench or nut driver sized for a 6 mm across-flats hex body. Always de-energize and lock out the equipment before servicing any control board or panel assembly. Avoid over-torquing stainless steel fasteners to prevent thread galling, which is a common issue with 303 stainless hardware. Verify mating thread engagement depth is sufficient on both the male and female ends before final assembly.
