Electro Hardware MMX1602M12MSC-1 Hex Standoff M5x0.8

Product Description

The ELECTRO HARDWARE MMX1602M12MSC-1 is a male-male hex circuit board standoff designed to create fixed spacing between PCBs, panels, and chassis assemblies. It features an M5 x 0.8 thread on both ends, a 3.5 mm overall length, and a hex body measuring 8 mm across the flats. Manufactured from Grade 2 steel with a zinc-plated finish, this standoff meets the QQ-S-633 fastener standard. The hex body allows precise tightening with standard hex tooling, making installation repeatable and secure. It is suited for electronics assembly, control panel builds, and circuit board mounting applications found in HVAC control systems, electrical enclosures, and similar trade equipment.

This standoff is used wherever a male-threaded post is needed on both ends to stack or separate circuit boards and mounting panels at a defined distance. Typical applications include residential and commercial HVAC control board assemblies, electrical panel subassemblies, and industrial enclosure builds. The metric M5 x 0.8 thread sizing positions this fastener in mid-range PCB mounting configurations where imperial hardware is not specified. Electricians, controls technicians, and electronics assembly personnel are the primary installers. The zinc plating provides corrosion resistance suitable for indoor enclosure environments.

Key Features

• Male-male thread configuration on both ends for stacking or panel-to-board mounting
• M5 x 0.8 metric thread size with 10 mm thread length
• 3.5 mm overall length for tight, close-clearance PCB spacing
• Hex body at 8 mm across the flats for wrench or socket installation
• Grade 2 steel construction with zinc-plated finish meeting QQ-S-633 standard
• Length tolerance of -0.150 mm to 0.150 mm for consistent, repeatable fitment

Compatibility

Designed as an OEM-style replacement or direct-fit standoff for circuit board and panel mounting assemblies requiring M5 x 0.8 male-male hex fasteners with a 3.5 mm overall length.

Installation Notes

Installation is typically performed by electronics assembly technicians, electricians, or controls technicians during panel assembly or PCB replacement. Power down and de-energize all circuits in the enclosure before handling circuit boards or fasteners. Use an appropriately sized hex wrench or socket matched to the 8 mm across-flats body to avoid rounding the hex. Follow applicable NEC guidelines when working inside electrical enclosures.
