Electro Hardware MM1309M12MSC-1 Hex Standoff 6-32 1/4 in

Product Description

The ELECTRO HARDWARE MM1309M12MSC-1 is a male-to-male hex circuit board standoff designed to create fixed spacing between PCBs, chassis panels, or mounting surfaces in electronic assemblies. Threaded 6-32 on both ends, this standoff measures 0.25 inches overall length with a 3/16-inch (0.1875 inches) hex width across flats. The body is machined from Grade 2 steel and finished with a zinc plating for corrosion resistance. It conforms to fastener standard QQ-S-633 and carries a hex body shape for secure tool engagement during installation. Electronics technicians, panel builders, and enclosure assemblers use this type of hardware when stacking or securing PCBs inside control enclosures, HVAC control boards, or electrical panels.

This standoff is suited for circuit board mounting applications in residential and commercial electronic assemblies. Typical uses include securing control boards inside HVAC units, electrical enclosures, and industrial equipment where a short, rigid spacer with male threads on both ends is required. The compact 0.25-inch overall length makes it appropriate for tight board-to-board or board-to-chassis spacing. Sold in single-unit quantities, it is a direct-replacement fastener for light electronic assembly and service work.

Key Features

• Male-to-male thread configuration on both ends for back-to-back board or chassis attachment
• 6-32 unified coarse thread size compatible with standard PCB mounting hardware
• Hex body shape allows engagement with standard hex drivers and wrenches
• Grade 2 steel construction with zinc plating meets QQ-S-633 fastener standard
• 0.25-inch overall length suits tight-clearance board spacing applications
• Length tolerance of -0.005 to 0.005 inches ensures consistent fit across assemblies

Compatibility

Designed as an OEM-style replacement or service fastener for circuit board mounting applications requiring a 6-32 male-male hex standoff with a 0.25-inch overall length.

Installation Notes

Installation is performed by electronics technicians or electricians working on control board assemblies. Power down and de-energize the equipment fully before accessing any circuit board or enclosure interior. Use a properly sized hex driver or nutdriver matching the 3/16-inch width across flats to avoid rounding the hex body. Follow applicable NEC guidelines when working inside electrical enclosures.
