Electro Hardware MMX1735M09MSC-1 Hex Standoff M5x0.8

Product Description

The ELECTRO HARDWARE MMX1735M09MSC-1 is a male-male hex circuit board standoff designed to create fixed spacing between PCBs, enclosure panels, and mounting surfaces in electronic assemblies. It features an M5 x 0.8 thread on both ends and a 20 mm overall length, making it suitable for applications that require a precise, rigid standoff with external threads at each end. The body is machined from Grade 18-8 303 stainless steel with a passivated finish that resists corrosion in demanding environments. This standoff meets the QQ-S-763 fastener standard and is appropriate for installation by electronics technicians, OEM assemblers, and field service professionals working on control boards and electrical enclosures.

This standoff is used in PCB mounting applications where two externally threaded connection points are required, such as stacking circuit boards, securing control boards inside HVAC equipment enclosures, industrial panel assemblies, and electrical equipment housings. The hex body geometry allows installation and removal with a standard wrench or hex driver, simplifying service access in tight enclosures. Its metric M5 x 0.8 thread sizing fits metric-threaded mounting holes commonly found in control boards and DIN-rail enclosures across HVAC, electrical, and light industrial equipment.

Key Features

• M5 x 0.8 male threads on both ends for dual external thread engagement
• 20 mm overall length with 20 mm body length for consistent, predictable stack height
• 10 mm width across flats hex body for wrench-driven installation and removal
• Grade 18-8 303 stainless steel construction for corrosion resistance
• Passivated finish per QQ-S-763 fastener standard
• Thread length range of 9 mm to 10 mm accommodates standard metric mounting configurations

Compatibility

Designed as an OEM-style metric standoff for circuit board and enclosure panel mounting applications using M5 x 0.8 threaded mounting holes.

Installation Notes

Installation should be performed by a qualified technician with the assembly fully de-energized and isolated from power before beginning. Use an appropriately sized wrench or hex driver matched to the 10 mm width across flats to avoid rounding the hex body. Do not over-torque when threading into PCB-mounted inserts or thin panel materials, as stainless steel fasteners can gall if driven without proper technique. Follow applicable equipment manufacturer torque guidelines and relevant electrical enclosure codes when integrating standoffs into control board assemblies.
