Electro Hardware MP1047M09F16M3 Female Hex Standoff M3

Product Description

The ELECTRO HARDWARE MP1047M09F16M3 is a female hex circuit board standoff designed to create fixed spacing between PCBs or between a PCB and a mounting surface. The standoff features an M3 x 0.5 thread size with a 6.4 mm thread depth, a 24 mm overall length, and a 6 mm hex width across flats. Constructed from grade 303 stainless steel with a plain, bright uncoated finish, it meets QQ-S-763 standards for stainless steel fasteners. Electronics assemblers, field service technicians, and panel builders use this hardware in control board assemblies, industrial enclosures, and similar applications where precise board standoff height and corrosion resistance are required.

This standoff is suited for metric PCB mounting applications where an M3 thread interface is called for. Typical use cases include mounting control boards inside HVAC equipment, electrical panels, automation enclosures, and other assemblies requiring a fixed board-to-surface gap. The partially threaded female design accepts an M3 fastener on one end, making it compatible with standard metric screw-mount board assemblies. No specific equipment model compatibility was provided by the manufacturer for this part.

Key Features

• M3 x 0.5 female thread with 6.4 mm thread depth for secure fastener engagement
• 24 mm overall length with a length tolerance of -0.13 to 0.13 mm for precise board spacing
• Hexagonal body with 6 mm width across flats for easy wrench or socket installation
• Grade 303 stainless steel construction meets QQ-S-763 fastener standards
• Plain, bright uncoated finish suitable for indoor and protected enclosure environments
• Partially threaded design allows for defined engagement depth without bottoming out

Compatibility

Designed as a metric M3 x 0.5 female hex standoff for PCB mounting applications in control boards, electrical panels, and industrial enclosures. No specific equipment or model compatibility was stated in the product data.

Installation Notes

Installation is typically performed by electronics assemblers or field service technicians using a hex wrench or open-end wrench sized to the 6 mm flats. Power down and de-energize any equipment before servicing circuit boards or installing standoffs in live panels. Avoid over-torquing into threaded inserts or PCB mounting holes, as stainless fasteners are susceptible to galling if driven under excessive force. Follow applicable enclosure and panel assembly standards for your application.
