Electro Hardware 1306M06F16256 Hex Standoff 2-56 Aluminum

Product Description

The ELECTRO HARDWARE 1306M06F16256 is a male-female hex circuit board standoff designed to create precise spacing between printed circuit boards and mounting surfaces or between stacked boards. Machined from aluminum alloy T3 to the QQ-A-225A Comp 2 fastener standard, it delivers a lightweight, corrosion-resistant solution for electronics assemblies. The standoff features a 2-56 thread size with a hex body shape measuring 3/16 inches across flats and an overall body length of 9/32 inches (0.2813 inches). The bright, uncoated finish keeps the aluminum surface clean for electrical and mechanical integrity in control board and panel assemblies.

This standoff is suited for residential and commercial electronic control board installations, including HVAC control boards, relay panels, and other low-voltage circuit board assemblies where precise board-to-board or board-to-chassis spacing is required. Licensed technicians and electronics assembly professionals use this hardware during panel fabrication, PCB mounting, and control board replacement work. The 2-56 thread size is common in small-format circuit board applications where fine-thread engagement in aluminum or brass-insert mounting points is needed.

Key Features

• Male-female hex configuration allows stacking multiple boards or mounting a board off a chassis surface
• 2-56 thread size with 5/32-inch thread length on the male end and 3/16-inch thread depth on the female end
• Hex body shape (3/16 inches across flats) enables wrench or socket tightening for secure torque application
• Aluminum T3 material keeps weight low at 0.11 pounds per package while resisting corrosion
• Meets QQ-A-225A Comp 2 fastener standard for dimensional and material consistency
• Length tolerance held to plus or minus 0.005 inches for precise board spacing

Compatibility

Designed as an OEM-style replacement or new-install standoff for circuit board assemblies using 2-56 threaded mounting points, including HVAC control boards, relay panels, and general electronics enclosures requiring hex standoff hardware.

Installation Notes

Circuit board standoffs are installed by licensed HVAC technicians, electricians, or electronics assembly professionals during control board mounting or panel fabrication. Always de-energize and lock out the control panel or equipment before servicing any circuit board or standoff hardware. Use an appropriately sized hex wrench or socket matching the 3/16-inch across-flats hex body to avoid rounding the standoff. Follow applicable NEC guidelines and equipment manufacturer torque recommendations when securing control board assemblies.
