Electro Hardware 1303M09F16256 Hex Standoff 2-56 3/16 in

Product Description

The ELECTRO HARDWARE 1303M09F16256 is a male-female hex circuit board standoff designed to create precise spacing between PCBs and mounting surfaces in electronic assemblies. Machined from 303 stainless steel with a passivated finish, it meets QQ-S-763 standards for corrosion resistance and dimensional consistency. The standoff measures 0.1875 inches overall length with a 3/16-inch hex body, and threads are sized 2-56 with a thread length of 5/32 inches. It is installed by electronics assembly technicians, field service engineers, and electricians building control panel assemblies requiring stable, non-corroding board supports.

This standoff is suited for use in low-voltage control boards, relay panels, HVAC control assemblies, and general electronic enclosures where a compact, corrosion-resistant spacer is required. The 2-56 thread size targets fine-thread PCB mounting applications common in residential and light commercial control boards. The hex body profile allows wrench engagement for torque-controlled installation, making it appropriate for production and service environments where board alignment and repeatability matter.

Key Features

• 303 stainless steel construction with passivated finish for corrosion resistance per QQ-S-763
• Male-female thread configuration allows stacking or direct board-to-chassis mounting
• Hex body shape enables wrench or socket engagement for secure installation
• 2-56 thread size with 5/32-inch thread length suits compact PCB fastening applications
• 0.1875-inch overall length with tight length tolerance of plus or minus 0.005 inches

Compatibility

Designed for use in circuit board assemblies requiring a 2-56 male-female hex standoff with a 3/16-inch hex body and 0.1875-inch overall length. Typical fitment includes PCB mounting and panel assembly applications where 2-56 threaded hardware is specified.

Installation Notes

Installation is performed by qualified electronics assembly technicians or licensed electricians. De-energize all circuits before servicing any control board or panel assembly. Use an appropriately sized hex wrench or nut driver to engage the hex body and avoid over-tightening, which can crack PCB mounting pads. Refer to the board manufacturer's mounting specifications and applicable NEC guidelines when installing standoffs in electrical enclosures.
