Electro Hardware MMX1635M06MSC-1 Hex Standoff M5x0.8

Product Description

The ELECTRO HARDWARE MMX1635M06MSC-1 is a male-male hex circuit board standoff machined from aluminum alloy to metric M5 x 0.8 thread specifications. It provides a threaded pillar between two circuit boards or between a board and a mounting surface, keeping assemblies separated, aligned, and mechanically secured. The overall length is 20 mm with a body length of 20 mm and a hex body shape measuring 8 mm across flats. Thread length options are 10 mm, 9 mm, and 9.5 mm depending on engagement requirements. Material grade is T-3 aluminum with a clear finish. This fastener is used by electronics assembly technicians, industrial automation integrators, and OEM equipment builders.

This standoff is suited for metric circuit board assemblies in industrial controls, HVAC control boards, electrical enclosures, and similar panel-mounted electronics. The M5 x 0.8 thread size is a common metric pitch found in mid-sized PCB mounting applications. Its aluminum construction keeps weight low while providing adequate structural rigidity for most low-vibration indoor electronic enclosures. Sold individually with a minimum order quantity of one unit.

Key Features

• Male-male configuration supports board-to-board or board-to-chassis stacking
• M5 x 0.8 metric thread on both ends for standard metric fastener compatibility
• Hex body shape at 8 mm across flats allows wrench tightening for secure torque application
• T-3 grade aluminum construction — lightweight and corrosion resistant under clear finish
• Meets QQ-A-225A Comp 2 material standard
• 20 mm overall length with length tolerance of -0.150 mm to +0.150 mm

Compatibility

Designed for use in metric circuit board assemblies requiring M5 x 0.8 male-male hex standoffs with a 20 mm overall length. Suitable as a direct replacement or original-build fastener wherever QQ-A-225A Comp 2 aluminum standoffs of this thread size and length are specified.

Installation Notes

Installation is performed by electronics assembly technicians or qualified electricians working on control panels and PCB assemblies. Power down and de-energize all circuits before handling or replacing circuit board hardware. Use an appropriately sized metric wrench on the 8 mm hex flats to achieve consistent seating without over-torquing the aluminum threads. Follow IPC assembly standards and any applicable equipment manufacturer guidelines when mounting circuit boards.
