Electro Hardware 1377M06F16256 Hex Standoff 2-56 2.5in

Product Description

The ELECTRO HARDWARE 1377M06F16256 is a male-female hex circuit board standoff designed to create fixed spacing between PCBs and mounting surfaces or between stacked boards. Machined from aluminum alloy T3 per the QQ-A-225A Comp 2 fastener standard, this standoff features a 2-56 thread size with a male thread on one end and a female threaded bore on the other. The hex body measures 3/16 inches (0.1875 inches) across flats, and the overall body length is 2.5 inches. The bright, uncoated finish is appropriate for indoor electronics enclosures and control panel assemblies where bare aluminum is acceptable. Electrical and electronics technicians install these standoffs during board-level assembly and equipment manufacture.

This standoff is used in residential and commercial electronics assemblies, control panels, and printed circuit board mounting applications where a 2-56 threaded fastener is specified. The male-female configuration allows boards to be stacked or offset from a chassis at a controlled, repeatable distance. Typical applications include instrument enclosures, relay panels, and custom PCB mounting frames in HVAC control systems, electrical equipment, and similar trade-installed hardware.

Key Features

• Male-female hex configuration for stackable PCB mounting and board-to-chassis spacing
• 2-56 thread size with 5/32-inch thread length on the male end and 3/16-inch thread depth on the female end
• 2.5-inch overall body length for precise board offset
• Aluminum T3 material per QQ-A-225A Comp 2 standard — lightweight and non-magnetic
• Hex body (3/16 inches across flats) allows standard hex driver or wrench installation
• Bright, uncoated finish suitable for general indoor electronics environments

Compatibility

Designed as a standard 2-56 threaded male-female hex standoff for use in circuit board assemblies, electronics enclosures, and control panel builds where 2-56 fastener spacing hardware is specified.

Installation Notes

Installation is performed by electronics technicians or electricians during board assembly or panel fabrication. Power down and de-energize all equipment before servicing any circuit board or control panel assembly. Use a correctly sized hex driver or nutdriver matching the 3/16-inch across-flats hex body to avoid rounding the standoff. Do not overtighten, as aluminum threads can strip or deform under excessive torque.
