Electro Hardware 1304M09F16256 Hex Standoff 2-56 7/32 in Ss

Product Description

The ELECTRO HARDWARE 1304M09F16256 is a male-female hex circuit board standoff designed to create precise spacing between PCBs, mounting panels, and enclosure surfaces. It features a 2-56 thread on both the male pin and female threaded bore, with an overall body length of 0.2188 inches (7/32 inch) and a width across flats of 0.1875 inches (3/16 inch). Constructed from 303-grade stainless steel with a passivated finish per QQ-S-763, this standoff resists corrosion and contamination in demanding environments. Electrical technicians and electronics assembly professionals install these fasteners where reliable board separation and secure mechanical attachment are required in tight-tolerance assemblies.

This standoff suits residential and commercial electronics assemblies, control panels, and PCB stacking applications where a compact, low-profile spacer is needed. The male-female hex configuration allows fasteners to thread onto the male end while the female end accepts a mating screw from an adjacent board or panel. The hexagonal body shape enables standard wrench or nutdriver installation, making it practical in production and field-service settings alike. The QQ-S-763 passivation standard ensures the stainless steel surface is free of free iron and contaminants, which is important in sensitive electrical enclosures.

Key Features

• Male-female hex configuration supports PCB stacking and panel mounting in a single fastener
• 2-56 thread size on both ends for compatibility with standard #2 machine screw hardware
• 303 stainless steel construction provides corrosion resistance in control-panel and enclosure environments
• Passivated finish meets QQ-S-763 standard, removing surface contaminants for use in sensitive assemblies
• Hex body shape accepts standard wrench or nutdriver for controlled installation torque
• Compact 7/32 inch overall length suits tight board-to-board or board-to-panel spacing requirements

Compatibility

Designed as an OEM-style replacement or new-install standoff for circuit board assemblies and control panel enclosures using 2-56 threaded hardware in inch-measurement configurations.

Installation Notes

Installation is typically performed by electronics technicians or licensed electricians during panel assembly or PCB service. Power down and de-energize the equipment fully before installing or removing standoffs in any live control panel or enclosure. Use a correctly sized nutdriver or hex wrench on the flat body to avoid rounding the hex and damaging surrounding board traces. Minimum order quantity is 10 units; verify quantity on hand before beginning a multi-board assembly run.
