Electro Hardware MP1011M09F16M3 Female Hex Standoff M3

Product Description

The ELECTRO HARDWARE MP1011M09F16M3 is a female hex circuit board standoff designed to create precise, rigid spacing between PCBs and mounting surfaces or between stacked boards. Manufactured from 303 stainless steel with a plain, bright uncoated finish, this standoff features an M3 x 0.5 internal thread that runs the full 6 mm thread depth across its 6 mm overall length. The hex body measures 6 mm across the flats, allowing standard hex drivers to seat and torque the fastener securely. Electronics assemblers, field technicians, and panel builders install these standoffs in control boards, enclosure assemblies, and equipment where corrosion resistance and dimensional stability are required.

This standoff is suited for metric PCB mounting applications in residential and commercial control panels, HVAC equipment circuit boards, electrical enclosures, and instrumentation assemblies. The M3 x 0.5 thread pitch is a common metric standard found across a wide range of electronic sub-assemblies and OEM equipment. Its compact 6 mm overall length makes it appropriate for tight stack-height applications where board clearance is critical. The fully threaded internal bore accepts an M3 screw from either end, enabling flexible assembly configurations.

Key Features

• M3 x 0.5 fully threaded female bore, 6 mm thread depth — full thread engagement for secure fastening
• 6 mm overall length and 6 mm hex width across flats for precise board standoff height
• 303 stainless steel construction meets QQ-S-763 specification for corrosion resistance
• Plain, bright uncoated finish — no coating thickness variability affecting dimensional tolerance
• Length tolerance of -0.13 to 0.13 mm for consistent stack height in multi-board assemblies
• Hex body profile accepts standard metric hex drivers and wrenches for repeatable installation

Compatibility

Designed as an OEM-style metric spacer for PCB and panel mounting applications requiring an M3 x 0.5 female threaded hex standoff with a 6 mm overall length.

Installation Notes

Install and remove using a properly sized metric hex driver or wrench sized to the 6 mm across-flats dimension to avoid rounding the hex body. De-energize and discharge all circuits before servicing any control board or panel assembly where these standoffs are used. Follow applicable enclosure and panel assembly guidelines under NFPA 70 (NEC) for electrical installations. Do not overtighten — use only the torque appropriate for M3 stainless steel hardware as specified in the assembly documentation for the host equipment.
