Electro Hardware MMF1809M09F16M4 Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MMF1809M09F16M4 is a male-female hex circuit board standoff designed to mount and space PCBs within enclosures, control panels, and electronic assemblies. Machined from 303 stainless steel with a bright uncoated finish, this standoff meets QQ-S-763 material standards. The M4x0.7 thread size on both the male and female ends provides a secure, repeatable connection between stacked boards or between a board and a mounting surface. With an overall length of 18.53 mm, a body length of 9.00 mm, and a 6.00 mm hex body, it accepts standard hex drivers for fast installation and removal during service.

This standoff is suited for use in residential and commercial electronic control assemblies, HVAC control boards, industrial enclosures, and any application requiring reliable board-to-board or board-to-chassis spacing. The hexagonal body shape allows wrench or nut-driver access in tight panel layouts. Electricians, panel builders, and electronics technicians routinely use standoffs of this type when assembling or servicing control boards in power distribution, HVAC, and automation equipment.

Key Features

• M4x0.7 male and female threads on opposing ends for stacked-board or chassis mounting
• 303 stainless steel construction meets QQ-S-763 standard for corrosion resistance and durability
• Bright uncoated finish maintains dimensional accuracy and thread fit
• 6.00 mm hex body accommodates standard hex drivers and nut drivers
• Overall length of 18.53 mm with a length tolerance of -0.150 to 0.150 mm for consistent spacing
• Metric measurement system for use in metric-spec assemblies and enclosures

Compatibility

Designed as an OEM-style replacement or new-installation standoff for metric M4x0.7 threaded PCB mounting applications in control panels, electronic enclosures, and circuit board assemblies.

Installation Notes

Installation is typically performed by electricians or electronics technicians during control board assembly or service. De-energize and lock out all power to the panel or enclosure before installing or removing standoffs. Use a correctly sized hex driver or nut driver on the 6.00 mm flats to avoid rounding the body. Apply only hand-tight torque unless a specific torque value is provided by the equipment manufacturer.
