Electro Hardware 1337M06F16256 Hex Standoff 2-56 1-1/4 in

Product Description

The ELECTRO HARDWARE 1337M06F16256 is a male-female hex circuit board standoff designed to separate and support printed circuit boards within electronic enclosures. The standoff features a 2-56 thread size, a 1.25-inch overall body length, and a 0.1875-inch width across flats. Machined from aluminum alloy T3 with a bright uncoated finish, it meets the QQ-A-225A Comp 2 material standard. The hex body shape allows for wrench engagement during installation, and the male-female configuration enables stacking multiple standoffs or securing a board to a panel in a single fastener pass. Electronics assemblers and field technicians working with control boards, relay panels, and enclosure assemblies are the primary installers.

This standoff is suited for use in residential and commercial electronic control assemblies, HVAC control boards, electrical enclosures, and similar low-voltage circuit board mounting applications. The 2-56 thread is common in compact PCB assemblies where space is limited. The 3/16-inch thread depth on the female end and 5/32-inch thread length on the male end provide consistent engagement for reliable board-to-panel or board-to-board spacing at a 1-1/4-inch separation distance.

Key Features

• Male-female hex configuration allows single-pass board mounting and standoff stacking
• 2-56 thread size for compact PCB assemblies
• 1.25-inch overall length provides consistent board-to-board or board-to-panel spacing
• Aluminum T3 material with bright uncoated finish meets QQ-A-225A Comp 2 standard
• Hex body shape accepts standard wrench or hex driver for secure installation
• Length tolerance of -0.005 to 0.005 inches ensures dimensional consistency

Compatibility

Designed as an OEM-style replacement or original-install fastener for circuit board assemblies that require 2-56 threaded hex standoffs with a 1-1/4-inch body length in aluminum construction.

Installation Notes

Installation is performed by electronics technicians or electricians working on control board assemblies. Power down the equipment and discharge any capacitors before handling circuit boards or installing standoffs. Use a properly sized hex driver or open-end wrench matched to the 3/16-inch width across flats to avoid rounding the hex body. Do not overtighten, as aluminum threads can strip under excessive torque.
