Electro Hardware MP1061M03F21M4 Female Hex Standoff M4

Product Description

The ELECTRO HARDWARE MP1061M03F21M4 is a female hex circuit board standoff designed to create precise, stable spacing between PCBs and mounting surfaces in electronic assemblies. Machined from brass with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff accepts an M4 x 0.7 metric thread with an 11.1 mm thread depth. The overall length is 31 mm and the hex body measures 6 mm across flats for secure tool engagement. It is partially threaded on the female end. Electronics assembly technicians, panel builders, and electrical contractors install these in control boards, industrial enclosures, and automation panels.

This standoff is used wherever metric-threaded PCB mounting hardware is required in residential, commercial, or industrial electronic assemblies. Typical applications include circuit board mounting in HVAC control panels, electrical enclosures, and equipment racks where consistent board-to-chassis spacing and a positive thread engagement are critical. The hex geometry allows installation with standard nut drivers or hex wrenches without slipping or marring adjacent components.

Key Features

• M4 x 0.7 female metric thread with 11.1 mm thread depth for secure fastener engagement
• 31 mm overall length with a length tolerance of -0.13 to 0.13 mm for consistent stack height
• 6 mm hex body width across flats allows standard nut driver or wrench installation
• Brass construction with zinc-plated finish provides corrosion resistance in panel environments
• Complies with ASTM B633 Type 1 and QQ-B-626 Comp 22 finish standards
• Partially threaded design for controlled engagement depth

Compatibility

Designed for use in any assembly requiring an M4 x 0.7 metric female hex standoff with a 31 mm overall length and 6 mm hex profile. Suitable for standard metric PCB mounting configurations in control boards and electronic enclosures.

Installation Notes

Power down and de-energize all circuits before installing or removing circuit board standoffs in any control panel or enclosure. Use a 6 mm nut driver or hex wrench to seat the standoff without applying excess torque that could strip the brass threads. Verify board-to-surface clearance matches the standoff length before finalizing the assembly. Installation should follow applicable electrical codes and the equipment manufacturer guidelines for the enclosure or board being serviced.
