Electro Hardware MP1023M09F16M3 Hex Standoff M3 X 0.5

Product Description

The ELECTRO HARDWARE MP1023M09F16M3 is a female hex circuit board standoff designed to create precise spacing and secure mounting between PCBs and chassis surfaces in electronic assemblies. Machined from 303 stainless steel with a plain bright finish, this standoff meets the QQ-S-763 material standard. The M3 x 0.5 internal thread runs fully through the 12 mm body length, providing 12 mm of thread depth for reliable fastener engagement on both ends. The hexagonal body measures 6 mm across flats, allowing standard hex tooling for installation and removal. This hardware is installed by electronics assembly technicians, electrical panel builders, and field service engineers working with control boards and enclosure-mounted PCBs.

This standoff is suited for metric fastener applications requiring a fully threaded female hex spacer in corrosion-resistant stainless steel. It is commonly used in industrial control panels, HVAC control board assemblies, electrical enclosures, and equipment requiring board-to-chassis or board-to-board separation. The plain uncoated finish is appropriate for environments where bare stainless is acceptable and additional coating is not required. The compact 12 mm overall length suits tight PCB stack-up tolerances in residential and light commercial equipment control sections.

Key Features

• Fully threaded female hex body with 12 mm thread depth for full fastener engagement
• M3 x 0.5 metric thread size compatible with standard M3 screws and posts
• 303 stainless steel construction meeting QQ-S-763 standard for corrosion resistance
• Hexagonal body with 6 mm width across flats for wrench or nut-driver installation
• Plain bright uncoated finish suitable for bare-metal assembly applications
• Consistent length tolerance of -0.13 to 0.13 mm for precise PCB standoff height

Compatibility

Designed as a metric M3 x 0.5 female hex standoff for use in PCB mounting, control board assemblies, and electrical enclosures requiring a fully threaded 12 mm stainless steel spacer.

Installation Notes

Installation is performed by electronics assembly technicians or licensed electricians during control panel or PCB assembly work. Power down all circuits and discharge any capacitors before working on live control boards. Use a properly sized hex wrench or nut driver on the 6 mm flats to avoid deforming the standoff body. Do not overtighten mating fasteners, as stainless steel hardware is susceptible to galling when assembled without lubrication or proper technique.
