Electro Hardware 1312M06F16440 Hex Standoff 4-40

Product Description

The ELECTRO HARDWARE 1312M06F16440 is a male-female hex circuit board standoff designed to separate and mount printed circuit boards at a fixed, precise distance within electronic enclosures and assemblies. Machined from aluminum alloy T3, this standoff features a 4-40 unified thread on both ends in a male-female configuration, allowing boards to be stacked or secured to a chassis. The hex body measures 3/16 inches across flats, giving technicians a clean wrench grip for installation. Overall length is 0.4688 inches (15/32 inches), with a thread length of 3/16 inches and a thread depth of 1/4 inch. It meets the QQ-A-225A Comp 2 fastener standard and ships with a bright, uncoated finish.

This standoff is used wherever a circuit board must be held off a chassis surface or stacked against a second board with consistent, controlled spacing. Common applications include control boards in HVAC equipment, industrial panels, electrical enclosures, and other assemblies where aluminum hardware is specified for its lightweight properties and corrosion resistance. The 4-40 thread size is standard for light-duty PCB mounting in residential and commercial equipment. Installation is typically performed by electronics technicians or field service professionals during board replacement or assembly work.

Key Features

• Precise length tolerance of -0.005 to 0.005 inches for consistent board spacing
• UNSPSC Code 31161816

Compatibility

Designed as a standard 4-40 male-female hex circuit board standoff for use in PCB mounting applications requiring an aluminum uncoated fastener in the inch measurement system.

Installation Notes

Installation is performed by qualified electronics technicians or electrical tradespeople. Power down and de-energize all equipment before handling circuit boards or installing standoffs. Use a properly sized hex wrench or nut driver matched to the 3/16-inch flats to avoid stripping the body. Do not over-torque; aluminum threads are susceptible to galling and cross-threading if forced.
