Electro Hardware 1310M09F16256 Hex Standoff 2-56 Ss

Product Description

The ELECTRO HARDWARE 1310M09F16256 is a male-female hex circuit board standoff designed to create precise spacing between stacked PCBs or between a board and a mounting surface. Machined from 303 stainless steel with a passivated finish per QQ-S-763, this standoff delivers corrosion resistance and dimensional consistency in demanding environments. The hex body measures 3/16 inches across flats and the overall body length is 0.4063 inches (13/32 inch). The male thread extends 5/32 inch and the female thread depth is 3/16 inch, both sized to the 2-56 thread standard. Electronics assembly technicians and PCB board-level service personnel are the primary installers of this hardware.

This standoff is suited for use in electronics enclosures, control boards, and instrumentation panels where repeatable board-to-board or board-to-chassis separation is required. It is appropriate for residential and commercial control assemblies, industrial electronics, and HVAC or electrical control board fabrication where a 2-56 thread pattern is specified. The passivated stainless steel construction makes it suitable for environments with moderate humidity or exposure to mild contaminants. Its compact hex profile allows standard hex driver or wrench installation in tight PCB layouts.

Key Features

• Male-female configuration enables stacking of additional standoffs or direct PCB-to-chassis mounting in a single fastener
• 303 stainless steel construction with passivated finish meets QQ-S-763 fastener standard
• 2-56 thread size on both the male and female ends for broad PCB hardware compatibility
• Hex body profile allows torque application with standard hex drivers or wrenches without marring the body
• Overall length of 0.4063 inches (13/32 inch) suits tight-clearance board stacking applications
• Length tolerance of -0.005 to 0.005 inches supports consistent stack height across multi-board assemblies

Compatibility

Designed as an OEM-style replacement or new-installation fastener for circuit board assemblies that specify a 2-56 male-female hex standoff with a 3/16 inch hex width and 13/32 inch body length.

Installation Notes

Installation is performed by electronics assembly technicians or control board service personnel. Power down and de-energize any board or enclosure completely before installing or removing standoffs. Use a correctly sized hex driver or nutdriver matched to the 3/16 inch across-flats dimension to avoid rounding the hex. Do not over-torque the male thread into the mating female receptacle, as 2-56 threads in stainless steel are susceptible to galling if driven without proper thread engagement alignment.
