Electro Hardware MP1041M09F16M4 Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MP1041M09F16M4 is a female hex circuit board standoff designed to create precise spacing and secure mechanical attachment between circuit boards and chassis panels or between stacked boards. Manufactured from 303 stainless steel with a plain bright finish, this standoff features an M4 x 0.7 female thread, a 21 mm overall length, and a 21 mm thread depth — meaning the thread runs the full body length. The hex body shape with a 6 mm width across flats allows for standard wrench or hex driver installation. It meets the QQ-S-763 fastener standard for stainless steel hardware. Electronic assembly technicians and board-level hardware installers work with this type of standoff in both industrial and commercial applications.

This standoff is suited for use in electronic enclosures, control panels, and circuit board assemblies where a durable, corrosion-resistant spacer and threaded mounting point are required. The metric M4 x 0.7 thread size is common in PCB mounting applications across industrial controls, HVAC control boards, electrical enclosure assemblies, and similar equipment. The plain finish maintains dimensional accuracy without adding coating thickness that could affect thread fit. Minimum order quantity is 10 pieces.

Key Features

• Female M4 x 0.7 thread, fully threaded to 21 mm depth for maximum engagement flexibility
• 303 stainless steel construction meets QQ-S-763 fastener standard for corrosion resistance
• Hex body with 6 mm width across flats — compatible with standard hex wrenches and nut drivers
• Plain bright finish — no coating to affect thread tolerances or dimensional fit
• 21 mm overall length provides consistent board-to-surface spacing in metric assemblies
• Length tolerance of -0.13 mm to +0.13 mm for precise stack-up control

Compatibility

Designed for use in metric M4 x 0.7 threaded circuit board mounting applications. Suitable as a replacement or new-install standoff wherever a female hex stainless steel standoff of 21 mm OAL and 6 mm across flats is specified.

Installation Notes

De-energize all equipment and discharge any stored electrical energy before installing or removing circuit board hardware. Use a 6 mm hex wrench or appropriately sized nut driver to drive the standoff to the required torque per the equipment manufacturer's board mounting specification. Avoid over-tightening, which can crack PCB substrate or distort the hex body. Follow applicable assembly and electrical enclosure codes for the equipment type being serviced.
