Electro Hardware MMX1502M09MSC-1 Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MMX1502M09MSC-1 is a male-male hex circuit board standoff designed to create fixed spacing between PCBs or between a PCB and a mounting surface. It features an M4 x 0.7 thread on both ends and measures 3.5 mm overall length with a 6 mm hex width across flats. Constructed from Grade 18-8 303 stainless steel with a passivated finish, it meets the QQ-S-763 fastener standard. This standoff is used in electronic assembly, control panel fabrication, and industrial enclosure work where corrosion resistance and precise board spacing are required.

This standoff is suited for metric fastener applications in low-voltage control boards, industrial electronics, HVAC control panel assemblies, and similar enclosure builds. The hex body allows installation and removal with standard hex drivers or wrenches. Thread lengths range from 8.5 mm to 9.5 mm, offering slight engagement flexibility during board-level assembly. It is typically installed by electronics assemblers, control panel builders, and field technicians performing PCB-level service work.

Key Features

• Male-male hex configuration for board-to-board or board-to-chassis standoff applications
• M4 x 0.7 metric thread on both ends for standard metric fastener compatibility
• Grade 18-8 303 stainless steel construction for corrosion resistance
• Passivated finish per QQ-S-763 fastener standard
• 6 mm hex width across flats allows installation with standard hex drivers or wrenches
• Length tolerance of -0.150 mm to 0.150 mm for precise board spacing

Compatibility

Designed for use in metric M4 x 0.7 threaded circuit board standoff applications. Suitable for PCB mounting, control board assemblies, and industrial enclosure builds requiring a male-male hex standoff with a 3.5 mm body length.

Installation Notes

Power down all equipment and discharge any stored energy before working on control boards or panel assemblies. Use an appropriately sized hex driver or wrench sized to the 6 mm flats to avoid rounding the hex body during installation. Do not overtighten — hand-snug plus a controlled partial turn is appropriate for threaded standoffs in circuit board applications. Follow applicable IPC assembly standards and enclosure manufacturer guidelines where specified.
