Electro Hardware MP1023M09F16M4 Female Hex Standoff M4

Product Description

The ELECTRO HARDWARE MP1023M09F16M4 is a female hex circuit board standoff designed to create precise spacing between PCBs and mounting surfaces in electronic assemblies. Machined from 303 stainless steel with a plain, bright uncoated finish, this standoff meets the QQ-S-763 stainless steel specification. The metric M4 x 0.7 internal thread runs the full 12 mm length of the body, providing a fully threaded engagement depth of 12 mm. The hex body measures 6 mm across flats, allowing standard hex tooling for secure installation. Licensed electronics assemblers, PCB technicians, and electrical panel builders install this type of fastener during board mounting and enclosure assembly operations.

This standoff suits applications where corrosion resistance and dimensional consistency are required in PCB assemblies, control panels, and electronic enclosures. The metric M4 thread size is common in industrial electronics, telecom equipment, and automation control boards. The 12 mm overall length provides a specific standoff height to maintain board-to-surface clearance for airflow or component access. The plain finish keeps the stainless steel bright and uncoated, making it suitable for environments where conductivity or cleanliness standards are a factor.

Key Features

• Fully threaded M4 x 0.7 female thread with 12 mm thread depth for maximum engagement
• 303 stainless steel construction meets QQ-S-763 fastener standard for corrosion resistance
• Hex body at 6 mm across flats accepts standard metric hex wrenches and nut drivers
• Plain bright uncoated finish preserves surface conductivity and suits cleanroom-compatible assemblies
• Length tolerance of -0.13 mm to +0.13 mm ensures consistent board standoff height across assemblies

Compatibility

Designed as an OEM-style metric standoff for PCB mounting applications requiring an M4 x 0.7 female hex standoff with a 12 mm overall length and 6 mm hex body.

Installation Notes

Install using a metric hex wrench or nut driver sized for a 6 mm across-flats hex body. De-energize all boards and panels completely before installing or removing standoffs in live assemblies. Avoid overtightening against PCB mounting holes to prevent board stress or cracking. Follow applicable IPC assembly standards and enclosure manufacturer torque guidelines for standoff installation in electronic equipment.
