Electro Hardware 1304M06F16256 Hex Standoff 2-56

Product Description

The ELECTRO HARDWARE 1304M06F16256 is a male-female hex circuit board standoff machined from aluminum alloy and supplied in an uncoated, bright finish. Sized for 2-56 thread engagement, it provides a fixed standoff post on one end and a threaded receiver on the other, allowing boards to be stacked or secured at a consistent height above a chassis or mounting surface. The overall body length is 0.2188 inches (7/32 inches) with a width across flats of 0.1875 inches (3/16 inches). It meets the QQ-A-225A Comp 2 material standard and is manufactured to a length tolerance of plus or minus 0.005 inches. Electronics assemblers and PCB technicians install these fasteners in production and field-service applications.

This standoff is suited for light-duty electronic assemblies where aluminum construction is preferred over steel for weight savings or corrosion considerations. Typical installations include securing circuit boards inside HVAC control enclosures, electrical panels, and other equipment housings where consistent board spacing and reliable thread engagement are required. The hex body shape allows installation with standard hex drivers or small wrenches. Minimum order quantity is 10 pieces; package quantity is 1.

Key Features

• Male-female thread configuration for board stacking or chassis mounting
• 2-56 thread size with a 5/32-inch thread length on the male end and 3/16-inch thread depth on the female end
• Hex body shape facilitates tool-assisted installation and removal
• Aluminum construction per QQ-A-225A Comp 2, Material Grade T3
• Bright uncoated finish; no plating to affect dimensional tolerances
• Length tolerance held to plus or minus 0.005 inches for consistent board height

Compatibility

Designed as a standard 2-56 male-female hex standoff for circuit board assemblies requiring an aluminum fastener meeting QQ-A-225A Comp 2 specifications.

Installation Notes

Install and remove using a hex driver or small open-end wrench sized for 3/16-inch across-flats hardware. Always de-energize the assembly and discharge any stored energy before working on circuit boards. Avoid over-torquing the 2-56 threads, as aluminum fasteners at this size are susceptible to thread stripping. Follow applicable IPC assembly standards and the equipment manufacturer's torque guidance for small-pitch fasteners.
