Electro Hardware MMX1607M09MSC-1 Hex Standoff M5x0.8

Product Description

The ELECTRO HARDWARE MMX1607M09MSC-1 is a male-male hex circuit board standoff designed to create fixed spacing between PCBs and mounting surfaces in electronic assemblies. Manufactured from Grade 18-8 303 stainless steel with a passivated finish, it delivers corrosion resistance suited to demanding environments. The standoff features an M5 x 0.8 thread on both ends, a 6 mm overall length, an 8 mm hex body width across flats for wrench engagement, and a thread length of 9.5 mm. It meets the QQ-S-763 fastener standard. Electronics assembly technicians, panel builders, and electrical contractors install these fasteners when securing control boards, relay panels, and enclosure-mounted circuit cards.

This standoff is used in light industrial, commercial, and residential electrical enclosure assemblies wherever a rigid, corrosion-resistant metal spacer is required between stacked PCBs or between a board and a mounting plate. Typical applications include control panel fabrication, HVAC circuit board mounting, and custom electrical enclosure builds requiring metric fasteners with a hex drive profile for precise torque control during assembly.

Key Features

• Male-male threaded ends accept M5 x 0.8 metric fasteners on both sides
• Grade 18-8 303 stainless steel construction for corrosion resistance
• Passivated finish per QQ-S-763 fastener standard
• Hex body profile allows wrench or nut driver installation
• 8 mm width across flats for standard hex tooling
• 6 mm overall body length provides consistent PCB standoff spacing

Compatibility

Designed as an OEM-style replacement or new-installation metric standoff for circuit board mounting applications requiring an M5 x 0.8 male-male hex fastener with a 6 mm body length.

Installation Notes

Installation is typically performed by electronics assembly technicians or licensed electricians during panel build or control board service. De-energize all circuits and discharge any stored energy before handling circuit boards or standoffs in live enclosures. Use a hex wrench or nut driver sized to 8 mm across flats to seat the standoff without over-torquing, which can crack PCB mounting holes. Follow applicable NEC guidelines for enclosure assembly and fastener selection.
