Electro Hardware 1306M12F21256 Hex Standoff 2-56

Product Description

The ELECTRO HARDWARE 1306M12F21256 is a male-female hex circuit board standoff designed to separate and support printed circuit boards within electronic enclosures and control panel assemblies. The standoff features a 2-56 unified thread on both the male and female ends, a hexagonal body shape measuring 3/16 inches across flats, and an overall body length of 9/32 inches (0.2813 inches). Constructed from steel with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-S-633 standards, this standoff provides corrosion resistance suitable for indoor electronic and industrial control applications. Installation is performed by electronics technicians, panel builders, and field service professionals working on control boards and enclosure assemblies.

This standoff is used in residential and commercial control panel assemblies, HVAC control boards, electrical enclosures, and similar electronic mounting applications where a threaded male post on one end and a threaded female receiver on the other are required to stack or space circuit boards at a fixed distance. The 2-56 thread size and compact hex body make it appropriate for fine-pitch circuit board mounting work in tight enclosure spaces.

Key Features

• Male-female configuration allows circuit boards to be stacked or spaced at a fixed standoff distance
• 2-56 unified thread on both ends for fine-pitch circuit board fastening
• Hexagonal body profile accepts a standard hex wrench for secure installation and removal
• Steel construction with zinc plating meets ASTM B633 Type 1 and QQ-S-633 corrosion resistance standards
• Compact overall length of 9/32 inches suits low-profile enclosure assemblies
• Thread length of 5/32 inches on the male end provides adequate thread engagement for 2-56 fasteners

Compatibility

Designed as an OEM-style replacement or new-installation standoff for circuit boards and control panels using 2-56 unified thread fastener patterns in standard hex standoff configurations.

Installation Notes

Installation is performed by electronics technicians or licensed electricians working on control panel assemblies. De-energize and lock out all power to the enclosure or control board before beginning standoff installation or removal. A hex wrench or hex socket sized for 3/16 inch across flats is required to torque the standoff body. Follow applicable NEC guidelines for enclosure work and handle circuit boards using proper electrostatic discharge precautions.
