Electro Hardware MM1709M09-MSC Hex Standoff 8-32 1/4 in

Product Description

The ELECTRO HARDWARE MM1709M09-MSC is a male-male hex circuit board standoff designed for use in electronic assemblies, control panels, and PCB mounting applications. Machined from Grade 18-8 303 stainless steel with a passivated finish, this standoff provides corrosion resistance and long service life in demanding environments. The fastener carries an 8-32 thread size on both ends and measures 0.25 inches overall length with a hex body shape measuring 0.375 inches across flats. It meets the QQ-S-763 federal specification for stainless steel fasteners. HVAC technicians, electricians, and panel builders use standoffs like this to maintain precise spacing between circuit boards and mounting surfaces.

This standoff is suited for residential and commercial applications where PCB mounting, control board installation, or enclosure assembly is required. Typical installations include HVAC control boards, electrical panel sub-assemblies, and industrial equipment enclosures. The male-to-male thread configuration allows stacking or direct fastening to a threaded boss on one side while accepting a nut or mating component on the opposite end. The compact 0.25-inch overall length makes it appropriate for tight-clearance board mounting situations.

Key Features

• Male-male thread configuration on both ends for flexible mounting arrangements
• Grade 18-8 303 stainless steel construction resists corrosion in humid or washdown environments
• Passivated finish meets QQ-S-763 federal specification for stainless steel fasteners
• Hex body shape allows wrench engagement for secure, torque-controlled installation
• Compact 0.25-inch overall length suitable for tight PCB-to-surface clearances
• 8-32 thread size is a widely used standard in electronic and control board assemblies

Compatibility

Designed as a standard 8-32 male-male hex standoff for circuit board and electronic enclosure mounting applications where a 0.25-inch OAL stainless steel fastener meeting QQ-S-763 is specified.

Installation Notes

Installation is typically performed by electricians or electronics technicians during control board assembly or panel fabrication. Power down and de-energize all equipment before working inside any enclosure or on any circuit board assembly. Use an appropriately sized open-end or socket wrench on the hex body to achieve proper engagement without over-tightening. Follow NEC guidelines and equipment manufacturer specifications when servicing or assembling electrical enclosures.
