Electro Hardware MM1458M12MSC-1 Hex Standoff 10-32 1in

Product Description

The ELECTRO HARDWARE MM1458M12MSC-1 is a male-male hex circuit board standoff designed to create fixed spacing between circuit boards, panels, or mounting surfaces in electronic assemblies. Machined from Grade 2 steel with a zinc-plated finish, this standoff meets QQ-S-633 fastener standards. It features a 10-32 threaded connection on both ends, a 1 inch overall length, and a hex body shape measuring 1/4 inch across flats. The zinc plating provides corrosion resistance suitable for indoor electronic and electrical panel applications. This hardware is installed by electronics technicians, electricians, and HVAC control board service professionals working with rack-mounted or PCB-based assemblies.

This standoff is used in applications where a rigid, threaded male-to-male connection is required to separate two circuit boards or to mount a board to a chassis at a fixed standoff distance. Common installation scenarios include HVAC control board assemblies, electrical enclosures, and industrial electronics panels. The hex body allows for wrench engagement during installation, making it suitable for confined spaces where finger-tightening is not sufficient.

Key Features

• Male-male threaded ends accept 10-32 fasteners on both sides
• Hex body profile (1/4 inch across flats) allows wrench tightening
• Grade 2 steel construction meets QQ-S-633 fastener standard
• Zinc-plated finish provides corrosion resistance for indoor use
• 1 inch overall length with tight length tolerance of plus or minus 0.005 inches

Compatibility

Designed as a standard 10-32 male-male hex standoff for use in circuit board mounting, electrical enclosure assembly, and electronic panel applications where a 1 inch spacing and inch-system fasteners are specified.

Installation Notes

Installation is typically performed by electronics technicians or licensed electricians during control board assembly or enclosure work. De-energize all circuits and discharge any capacitors before working inside electrical panels or HVAC control assemblies. Use an appropriately sized wrench on the hex flats to achieve a secure fit without over-torquing the threaded connections. Follow applicable NEC guidelines when installing hardware inside electrical enclosures.
