Electro Hardware MP1031M09F16M4 Female Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MP1031M09F16M4 is a female hex circuit board standoff designed to create precise spacing between PCBs, panels, and enclosure surfaces. Machined from 303 stainless steel with a plain bright finish, this standoff features a fully threaded M4 x 0.7 interior thread with a 16 mm thread depth equal to its overall length. The hex body measures 6 mm across the flats for standard wrench engagement. It meets the QQ-S-763 fastener standard and is suited for electronics assembly, control panel fabrication, and instrument enclosure builds where corrosion resistance and dimensional accuracy are required.

This standoff is used in metric fastener applications where a female-threaded hex spacer is needed to mount or stack circuit boards at a fixed standoff height. Typical applications include industrial control enclosures, HVAC control boards, electrical panel assemblies, and electronic equipment racks. The 16 mm overall length provides consistent board-to-surface clearance for component clearance and airflow. The stainless steel construction makes it suitable for environments with moderate humidity or chemical exposure where a plain steel standoff would be inadequate.

Key Features

• Female hex body with M4 x 0.7 fully threaded interior — accepts standard M4 metric screws from both ends
• 16 mm overall length with full 16 mm thread depth for maximum thread engagement
• 6 mm width across flats allows installation and removal with standard 6 mm hex wrench or nut driver
• 303 stainless steel construction with plain bright finish meets QQ-S-763 standard
• Length tolerance of -0.13 to 0.13 mm supports tight stacking tolerances in precision assemblies

Compatibility

Designed for use in metric fastener assemblies requiring an M4 x 0.7 female hex standoff. Compatible with any application calling for a fully threaded stainless steel hex standoff with 16 mm OAL per the QQ-S-763 fastener standard.

Installation Notes

Installation is performed by electronics technicians, electricians, or panel fabricators during board assembly or enclosure build. Power down and de-energize all circuits before installing or removing standoffs from live control boards. Use a 6 mm hex wrench or nut driver to torque to assembly specifications defined by the host equipment manufacturer. Avoid cross-threading by starting the mating screw by hand before applying tool torque.
