Electro Hardware MMX1602M09MSC-1 Hex Standoff M5x0.8

Product Description

The ELECTRO HARDWARE MMX1602M09MSC-1 is a male-male hex circuit board standoff designed for PCB mounting and spacing applications in electronic assemblies. It features an M5 x 0.8 thread size on both ends, a 3.5 mm overall body length, and an 8 mm width across flats for wrench engagement. Machined from Grade 18-8 303 stainless steel with a passivated finish, this standoff meets QQ-S-763 standards. The hex body profile allows secure torquing during installation and provides consistent board-to-board or board-to-chassis spacing in control panels, HVAC control boards, and similar electrical enclosures.

This standoff is suited for use in electronic control assemblies where metric fastening is required. Typical applications include PCB stacking, chassis mounting, and board-level spacing in HVAC equipment, electrical panels, and industrial control enclosures. The passivated stainless steel construction resists corrosion in environments where moisture or mild contaminants may be present. Installed by electronics assemblers, panel builders, and field technicians working on metric-threaded control board assemblies.

Key Features

• Male-male thread configuration on both ends for PCB-to-chassis or board-to-board stacking
• M5 x 0.8 metric thread size with thread length options of 9 mm, 9.5 mm, and 10 mm
• 3.5 mm hex body length with 8 mm width across flats for standard wrench fit
• Grade 18-8 303 stainless steel construction meets QQ-S-763 fastener standard
• Passivated finish provides corrosion resistance without added coating buildup
• Length tolerance of -0.15 mm to +0.15 mm for consistent stack height

Compatibility

Designed for use in metric M5 x 0.8 threaded circuit board and chassis mounting applications. Suitable for any PCB assembly or control enclosure requiring a male-male hex standoff with a 3.5 mm body length and 8 mm wrench flat.

Installation Notes

Install using an appropriately sized wrench or hex driver sized for 8 mm across flats. De-energize all equipment and discharge any capacitors before working inside control panels or circuit board assemblies. Avoid over-torquing, as stainless steel fasteners are susceptible to galling without proper technique or anti-seize compound. Follow applicable NEC and equipment manufacturer guidelines for PCB mounting hardware in electrical enclosures.
