Electro Hardware 1311M06F16440 Hex Standoff 4-40

Product Description

The ELECTRO HARDWARE 1311M06F16440 is a male-female hex circuit board standoff designed to create precise, fixed spacing between PCBs and chassis surfaces or between stacked boards. Machined from aluminum alloy to material grade T3 per QQ-A-225A Comp 2, this standoff features a 4-40 thread on both the male and female ends. The body measures 0.4375 inches in overall length with a 3/16-inch width across the hex flats, giving technicians a clean grip for installation with standard hex drivers or nut drivers. The bright, uncoated finish keeps weight minimal and avoids coating inconsistencies in tight board clearances. Electronics technicians and control board service pros install these as part of board mounting assemblies in HVAC controls, industrial panels, and similar equipment.

This standoff is suited for use in residential and light commercial control panels, HVAC circuit board assemblies, industrial enclosures, and any application requiring a secure, stackable PCB mounting solution. The male-female configuration allows boards to be spaced from a base surface while also accepting an additional fastener on the opposite end, making it adaptable for multi-layer board stacks or panel-mounted configurations. Sold individually with a minimum order quantity of 10 units.

Installation Notes

Installation is typically performed by electronics technicians or control board service professionals. Always power down and de-energize the equipment fully before handling circuit boards or installing standoffs. Use a properly sized hex driver or nut driver matching the 3/16-inch flats to avoid rounding the hex body. Follow applicable equipment manufacturer guidelines and NEC requirements when working inside energized enclosures.
