Electro Hardware MP1037M09F16M4 Female Hex Standoff M4

Product Description

The ELECTRO HARDWARE MP1037M09F16M4 is a female hex circuit board standoff designed to create fixed spacing between PCBs and mounting surfaces or between stacked boards in electronic assemblies. Machined from 303 stainless steel with a plain, bright uncoated finish, this standoff measures 19 mm in overall length with a fully threaded M4 x 0.7 female thread running the full 19 mm thread depth. The hex body profile measures 6 mm across flats, allowing a standard hex driver or wrench to apply controlled torque during installation. Weighing approximately 0.01 pounds, it is a compact fastener suited for precision electronics and control board mounting applications across HVAC, electrical, and industrial enclosure work.

This standoff is used wherever a threaded female-to-female spacer is needed to elevate or separate circuit boards from chassis surfaces, DIN rail mounts, or secondary PCB layers. Typical applications include control board mounting inside HVAC equipment enclosures, motor drives, power supply assemblies, and industrial control panels. The M4 metric thread size and fully threaded body make it a versatile choice for metric-fastened equipment designs. Installers assembling or servicing PCB stacks in tight enclosures will find the hex body shape practical for achieving consistent, repeatable standoff heights without rocking or misalignment.

Key Features

• Female hex standoff with M4 x 0.7 fully threaded interior, 19 mm thread depth
• 303 stainless steel construction with plain bright finish for corrosion resistance in electrical enclosures
• 6 mm width across flats enables standard hex tooling for torque control
• 19 mm overall length sets consistent board-to-surface spacing
• Meets QQ-S-763 fastener standard for stainless steel hardware
• Length tolerance of -0.13 to 0.13 mm supports precision PCB stack-up requirements

Compatibility

Designed as a metric M4 x 0.7 female hex standoff suitable for circuit board mounting applications where QQ-S-763 stainless steel hardware is specified.

Installation Notes

Installation is typically performed by electronics assembly technicians or licensed electricians working on control panel builds. Power down and de-energize all circuits before accessing or disturbing any mounted circuit boards. Use a hex driver or open-end wrench sized for 6 mm across flats to seat the standoff without overtightening, which can crack PCB mounting holes or damage threads. Follow applicable NEC guidelines and equipment manufacturer assembly specifications when mounting control boards inside electrical enclosures.
