Electro Hardware MM1301M06-MSC Hex Standoff 4-40 1/8 in Aluminum

Product Description

The ELECTRO HARDWARE MM1301M06-MSC is a male-male hex circuit board standoff machined from aluminum alloy to Grade T-3. It accepts a 4-40 thread on both ends and measures 1/8 inch overall length with a 3/16 inch width across flats. The hex body shape allows installation and removal with standard hex drivers or wrenches. This standoff is used to mount and space printed circuit boards (PCBs) within electronic enclosures, control panels, and equipment assemblies. It meets the QQ-A-225A Comp 2 fastener standard and carries a clear finish that preserves the natural aluminum appearance while providing light corrosion resistance.

This standoff is suited for light-duty PCB mounting applications in residential and commercial control systems, HVAC equipment boards, electrical enclosures, and industrial electronics assemblies. Its compact 1/8 inch overall length makes it appropriate for tight board-to-board or board-to-chassis spacing requirements where minimal standoff height is needed. Electricians, electronics technicians, and controls specialists typically install this type of hardware during panel build, board replacement, or field repair work.

Key Features

• Male-male thread configuration on both ends accepts 4-40 fasteners for stacking or direct chassis attachment
• Hex body shape allows torquing with a standard hex wrench or nutdriver without slipping
• Grade T-3 aluminum construction provides lightweight, non-magnetic fastening
• Clear finish meets QQ-A-225A Comp 2 standard for material and surface quality
• 1/8 inch overall length suits minimal-clearance PCB spacing requirements
• Inch measurement system with a length tolerance of -0.005 to 0.005 inch for consistent fit

Compatibility

Designed as an OEM-style replacement or new-installation standoff for PCBs and control panels using 4-40 inch-series threaded hardware.

Installation Notes

De-energize all circuits and discharge any capacitors before working inside control panels or electronic enclosures. Use a hex wrench or nutdriver sized for the 3/16 inch width across flats to seat the standoff without stripping the aluminum threads. Do not overtighten — aluminum threads are susceptible to galling and cross-threading. Follow applicable NEC guidelines for enclosure work when installing standoffs inside electrical equipment.
