Electro Hardware MP1011M03F21M3 Hex Standoff M3 Brass

Product Description

The ELECTRO HARDWARE MP1011M03F21M3 is a female hex circuit board standoff designed to create precise spacing between PCBs and mounting surfaces in electronic assemblies. This standoff features an M3 x 0.5 metric thread, a 6 mm overall length, and a fully threaded internal bore with a 6 mm thread depth, meaning the thread runs the full length of the body. The hexagonal body measures 6 mm across flats, allowing standard hex drivers and wrenches to seat the fastener securely. Constructed from brass with a zinc-plated finish that meets ASTM B633 Type 1 and QQ-B-626 Comp 22, it provides corrosion resistance appropriate for board-level hardware in control panels, HVAC equipment electronics, and similar enclosures. Licensed electricians, control board technicians, and electronics assembly professionals are the primary installers.

This standoff is suited for metric PCB mounting applications across residential and commercial equipment including HVAC control boards, electrical enclosures, industrial control panels, and OEM electronic assemblies. Its fully threaded female interior accepts an M3 x 0.5 screw from both the board side and the mounting surface side, making it a straightforward solution for stacked-board configurations or panel-mount PCB installations where a defined standoff height is required.

Key Features

• M3 x 0.5 metric thread, fully threaded female bore through the full 6 mm body length
• Hex body profile at 6 mm across flats for positive wrench engagement during installation
• Brass construction with zinc-plated finish for corrosion resistance
• Meets ASTM B633 Type 1 and QQ-B-626 Comp 22 finish standards
• Length tolerance of -0.13 mm to 0.13 mm for precise board spacing

Compatibility

Designed as a metric M3 x 0.5 female hex standoff suitable for PCB mounting applications requiring a 6 mm standoff height in electronic assemblies and control panel enclosures.

Installation Notes

Installation is typically performed by electronics assembly technicians, electricians, or field service personnel working on control board assemblies. Power down and de-energize all equipment before accessing any circuit board or control enclosure. Use a properly sized hex wrench or nut driver matched to the 6 mm across-flats dimension to avoid rounding the body. Do not overtighten into threaded inserts or PCB mounting holes, as brass fasteners are susceptible to thread damage under excessive torque.
