Electro Hardware MP1027M09F16M3 Hex Standoff M3 Ss

Product Description

The ELECTRO HARDWARE MP1027M09F16M3 is a female hex circuit board standoff designed to create fixed spacing between PCBs and mounting surfaces in electronic assemblies. Machined from 303 stainless steel with a plain, bright uncoated finish, this standoff meets the QQ-S-763 federal specification for stainless steel fasteners. It carries an M3 x 0.5 female thread, a 14 mm overall length with a fully threaded 14 mm thread depth, and a 6 mm hex body width across flats. The hex profile allows installation with a standard hex driver or wrench, making it suitable for precise torque application without slipping.

This standoff is used in electronic and electromechanical assemblies where a PCB must be secured at a fixed, controlled height above a chassis or panel. Common applications include industrial control panels, HVAC control boards, power supply assemblies, and enclosures where corrosion resistance is a priority. The stainless steel construction makes it appropriate for environments with moderate moisture exposure. It is typically installed by electronics assembly technicians, panel builders, or field service technicians during board replacement or new panel construction.

Key Features

• M3 x 0.5 female thread, fully threaded to 14 mm depth for maximum thread engagement
• 303 stainless steel construction meeting QQ-S-763 specification for corrosion resistance
• Hex body with 6 mm width across flats allows standard wrench or hex driver installation
• Plain, bright uncoated finish with no plating to interfere with electrical grounding contact
• Length tolerance of -0.13 to 0.13 mm for consistent PCB standoff height
• Metric dimensioning throughout for use with M3 hardware

Compatibility

Designed as an OEM-style replacement or new-build component for circuit board mounting applications requiring M3 x 0.5 female threaded hex standoffs with a 14 mm overall length.

Installation Notes

Power down and de-energize all equipment before removing or installing circuit board standoffs. A standard 6 mm hex wrench or nut driver is appropriate for driving this standoff body. Avoid over-torquing, which can strip the M3 threads or crack the PCB substrate. Follow IPC assembly standards and the equipment manufacturer's torque guidance for M3 hardware when available.
