Electro Hardware P309M06F16256 Hex Standoff 2-56 1/2 in

Product Description

The ELECTRO HARDWARE P309M06F16256 is a female hex circuit board standoff designed to create precise spacing between PCBs and mounting surfaces in electronic assemblies. Machined from aluminum alloy to a T3 material grade, this standoff features a 2-56 female thread with a full 1/2 inch thread depth and an overall length of 0.5 inches. The hexagonal body measures 3/16 inches across flats, allowing standard hex tooling for installation and removal. The plain, bright uncoated finish meets QQ-A-225A Comp 2 material standards. Electronics assembly technicians, panel builders, and field service techs working on control boards in HVAC, electrical, and industrial equipment use this hardware to mount and stack PCBs with consistent, repeatable standoff height.

This standoff is suited for use in residential and commercial control panel assemblies, circuit board mounting applications, and any enclosure build where secure PCB standoff spacing is required. Its compact hex profile and fine 2-56 thread make it appropriate for tight board layouts where larger fasteners cannot be accommodated. The all-aluminum construction keeps weight low in weight-sensitive assemblies. Minimum order quantity is 25 pieces; each package contains 1 unit.

Key Features

• 2-56 female thread with full 1/2 inch thread depth for secure PCB mounting
• 0.5 inch overall length provides consistent board-to-surface spacing
• Hexagonal body, 3/16 inches across flats, compatible with standard hex drivers and wrenches
• Aluminum T3 alloy construction — lightweight and corrosion-resistant for indoor enclosure use
• Plain bright uncoated finish; meets QQ-A-225A Comp 2 fastener standard
• Length tolerance held to plus or minus 0.005 inches for precise stack-up control

Compatibility

Designed as an OEM-style replacement or new-build component for PCB assemblies requiring 2-56 female hex standoffs with a 1/2 inch overall length and inch-system thread dimensions.

Installation Notes

Installation is performed by electronics assembly technicians or qualified electricians working on control board panels. Power down the equipment and discharge any capacitors before handling circuit boards. Use a properly sized hex driver or nut driver matching the 3/16 inch across-flats dimension to avoid stripping the hex body. Do not over-torque; aluminum threads are susceptible to galling and cross-threading if forced.
