Electro Hardware MP1019M03F21M4 Female Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MP1019M03F21M4 is a female hex circuit board standoff designed to create precise, threaded separation between PCBs and mounting surfaces or between stacked boards in electronic assemblies. The standoff features an M4 x 0.7 female thread that is fully threaded through its 10 mm overall length, providing the full thread depth for maximum thread engagement. The hex body measures 6 mm across flats, allowing standard hex tooling for secure installation. Constructed from brass with a zinc-plated finish, this standoff meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards for corrosion resistance and dimensional reliability. It is suited for use in control boards, electrical enclosures, and electronic equipment found across HVAC, electrical, and industrial applications.

This standoff is used wherever a threaded female-to-female or screw-to-female PCB mounting solution is required. Common applications include mounting control boards inside HVAC units, securing relay boards in electrical panels, and stacking PCBs in industrial control equipment. The metric M4 x 0.7 thread size makes this component appropriate for equipment manufactured to metric fastener standards. The compact 10 mm overall length suits low-profile board mounting configurations where minimal clearance between board layers or between a board and a chassis surface is required.

Key Features

• Fully threaded female M4 x 0.7 thread through the full 10 mm body length for maximum thread engagement
• Hex body shape with 6 mm width across flats accepts standard hex drivers and wrenches for secure torque application
• Brass construction provides good electrical conductivity and corrosion resistance in enclosed environments
• Zinc-plated finish meets ASTM B633 Type 1 and QQ-B-626 Comp 22 corrosion-resistance standards
• Length tolerance of -0.13 to 0.13 mm supports consistent board-to-board or board-to-chassis spacing
• Metric measurement system suits equipment designed to international or OEM metric fastener specifications

Compatibility

Designed as an OEM-style metric standoff for circuit board mounting applications requiring M4 x 0.7 female threads and a 10 mm standoff height in control boards, electrical enclosures, and electronic assemblies.

Installation Notes

Installation should be performed by a qualified electrician or electronics technician. De-energize all circuits and discharge any stored energy before handling circuit boards or fasteners in live panels. Use a hex driver or nut driver sized to the 6 mm across-flats dimension to avoid rounding the hex body. Do not overtighten; apply only enough torque to seat the standoff firmly against the mounting surface without deforming the brass body or stripping threads.
