Electro Hardware MM1358M09MSC-1 Hex Standoff 8-32 1in

Product Description

The ELECTRO HARDWARE MM1358M09MSC-1 is a male-to-male hex circuit board standoff designed to create fixed spacing between PCB layers or between a circuit board and a mounting surface. Machined from 18-8 grade 303 stainless steel with a passivated finish, this standoff resists corrosion and meets the QQ-S-763 federal specification for stainless steel fasteners. The 8-32 threaded ends engage mating hardware on both sides, providing a secure mechanical connection. At 1 inch overall length with a hex body width across flats of 3/16 inches, this standoff suits tight-tolerance PCB assemblies where consistent stack height is critical. Electricians, electronics technicians, and OEM assemblers typically install these as part of control board mounting hardware.

This standoff is used in residential and commercial control panel assemblies, custom enclosures, and OEM electronic equipment where circuit boards require mechanical support and precise vertical clearance. Its inch-system threading and compact hex profile make it well suited for industrial control boards, HVAC control modules, and relay panel assemblies. The passivated stainless steel construction is appropriate for environments where contact with mild moisture or cleaning agents is possible.

Key Features

• Male-to-male 8-32 threaded ends on both sides for secure board-to-board or board-to-chassis mounting
• 18-8 grade 303 stainless steel construction for corrosion resistance
• Passivated finish meeting QQ-S-763 federal fastener specification
• Hex body profile at 3/16 inches width across flats for standard wrench or socket installation
• 1 inch overall length with tight length tolerance of plus or minus 0.005 inches for precision stack height

Compatibility

Designed as an OEM-style replacement or new-installation standoff for circuit board assemblies using inch-system 8-32 hardware with 1 inch spacing requirements.

Installation Notes

Installation is performed by electronics technicians or electricians working on control panel assemblies. Always de-energize the equipment completely before handling circuit boards or installing standoffs. Use an appropriately sized hex wrench or socket on the hex body to tighten without over-torquing the threaded ends into mating hardware. Ensure mating fasteners are also 8-32 inch-system threads to prevent cross-threading or stripping.
