Electro Hardware MMX1535M12MSC-1 Hex Board Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MMX1535M12MSC-1 is a male-male hex circuit board standoff designed to create fixed spacing between PCBs and mounting surfaces in electronic assemblies. Threaded M4 x 0.7 on both ends, this standoff provides a secure mechanical connection in two directions. The hex body shape allows for wrench engagement during installation. Manufactured from Grade 2 steel with a zinc-plated finish per QQ-S-633, it delivers corrosion resistance suited to indoor electronic enclosures and control panels. Overall length is 20 mm with a 6 mm width across flats and thread lengths ranging from 8.5 mm to 9.5 mm. Total weight is 0.16 pounds per unit.

This standoff is used in circuit board mounting applications across HVAC control boards, electrical panels, industrial enclosures, and similar assemblies where rigid board-to-surface or board-to-board spacing is required. The metric M4 x 0.7 thread size is common in OEM electronics and replacement control board assemblies. It is typically installed by electricians, HVAC technicians, or electronics technicians during control board replacement or custom panel fabrication work.

Key Features

• Male-male threaded design allows rigid two-point board mounting
• M4 x 0.7 metric thread on both ends for standard compatibility
• Hex body shape (6 mm width across flats) accepts standard wrenches for torque control
• Grade 2 steel construction with zinc-plated finish per QQ-S-633
• 20 mm overall length with thread lengths of 8.5 mm, 9 mm, and 9.5 mm
• Length tolerance of -0.150 mm to 0.150 mm for precise fit

Compatibility

Designed as a metric M4 x 0.7 male-male hex standoff for use in circuit board assemblies requiring a 20 mm OAL steel spacer with zinc finish.

Installation Notes

Installation is performed by electricians or electronics technicians. Always de-energize and discharge the equipment before working on or near circuit boards. Use a hex wrench or nut driver sized to the 6 mm width across flats to seat the standoff without over-stressing the PCB substrate. Follow applicable NEC guidelines for enclosure work and observe any OEM torque recommendations for the mating hardware.
