Electro Hardware 1310M03F21256 Hex Board Standoff 2-56

Product Description

The ELECTRO HARDWARE 1310M03F21256 is a male-female hex circuit board standoff used to mount and space printed circuit boards within electronic enclosures and control panels. The standoff features a 2-56 thread on both the male and female ends, a hexagonal body that accepts a wrench or nut driver for secure installation, and a brass base material with a zinc-plate finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards. The overall body length is 0.4063 inches with a width across flats of 0.1875 inches. Electricians and control panel builders install these standoffs when stacking or mounting PCBs at a fixed, repeatable height inside enclosures.

This standoff is suited for use in low-voltage electronic assemblies, HVAC control boards, electrical enclosures, and industrial control panels where a reliable, non-conductive spacing solution is required between a PCB and a chassis or between stacked boards. The 2-56 thread size is common in light-duty PCB mounting applications. The zinc-plated brass construction provides corrosion resistance appropriate for indoor panel environments. Minimum order quantity is 10 pieces; each package contains 1 piece.

Key Features

• Male-female hex configuration allows boards to be stacked or mounted at a fixed standoff height
• 2-56 unified thread on both ends for compatibility with standard PCB mounting hardware
• Brass base with zinc-plate finish meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards
• Hex body shape accepts standard nut drivers and wrenches for clean, repeatable installation
• Overall body length of 0.4063 inches with 0.1875-inch width across flats for compact PCB spacing
• Thread length of 0.3125 inches (5/32 inch female thread depth, 5/32 inch male thread length) for secure engagement

Compatibility

Designed as a standard 2-56 male-female hex standoff for use in circuit board mounting applications requiring a 13/32-inch body length and 3/16-inch hex profile.

Installation Notes

Installation is typically performed by electricians or electronics technicians assembling or servicing control panels. Power down the control panel and discharge any stored energy before handling PCBs or standoffs. Use a nut driver or small wrench sized for a 3/16-inch hex to tighten standoffs without over-torquing the brass body. Follow applicable NEC guidelines when working inside energized enclosures.
