Electro Hardware MP1031M03F21M4 Hex Standoff M4 X 0.7

Product Description

The ELECTRO HARDWARE MP1031M03F21M4 is a female hex circuit board standoff designed to create fixed spacing between PCBs and mounting surfaces in electronic assemblies. It features a fully threaded M4 x 0.7 female thread with a 16 mm thread depth throughout its 16 mm overall length. The hex body measures 6 mm across flats, allowing standard hex drivers to seat and torque the fastener securely. Finished in zinc plating over brass, it meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards for corrosion resistance. Electronics technicians and panel builders use this standoff in control boards, HVAC equipment panels, and industrial enclosures where repeatable PCB standoff height and positive thread engagement are required.

This standoff is suited for metric-threaded PCB mounting applications in residential and commercial electronic control assemblies, including HVAC control boards, electrical enclosures, and industrial panel builds. The all-metric M4 x 0.7 thread form is common in OEM control board hardware across HVAC, power electronics, and automation equipment. The brass base material provides good thermal and electrical conductivity along with corrosion resistance appropriate for indoor equipment environments.

Key Features

• Fully threaded female M4 x 0.7 thread, 16 mm thread depth for maximum thread engagement
• 16 mm overall length provides consistent PCB standoff height
• Hex body, 6 mm width across flats, compatible with standard metric hex drivers and nut drivers
• Brass base material with zinc plating meets ASTM B633 Type 1 and QQ-B-626 Comp 22 corrosion resistance standards
• Length tolerance of -0.13 to 0.13 mm ensures precise stacking in multi-board assemblies

Compatibility

Designed as a metric M4 x 0.7 female hex standoff for use in PCB mounting and circuit board assembly applications requiring a fully threaded brass standoff with zinc finish.

Installation Notes

Installation is performed by electronics technicians or panel builders. Always power down and de-energize the equipment before servicing any control board or panel assembly. Use a metric hex driver or nut driver sized for 6 mm across flats to seat the standoff without over-torquing the brass body. Verify mating hardware uses the same M4 x 0.7 metric thread form to avoid cross-threading or thread damage.
