Electro Hardware P317M09F16256 Hex Standoff 5/8in 2-56

Product Description

The ELECTRO HARDWARE P317M09F16256 is a female hex circuit board standoff designed to space and mount printed circuit boards within enclosures, chassis, and electronic assemblies. Manufactured from 303 stainless steel with a plain bright finish, this standoff accepts a 2-56 thread and measures 0.625 inches overall length with a 3/16 inch width across flats. The fully threaded female interior runs 3/16 inch deep, providing secure thread engagement for mounting hardware. The hex body shape allows tool engagement for precise installation torque. This fastener meets the QQ-S-763 stainless steel specification and is suited for electronics assembly technicians, control panel builders, and field service professionals working on circuit board mounting applications.

This standoff is used in residential and commercial electronic control assemblies, OEM circuit board mounting applications, and field replacement scenarios where corrosion-resistant hardware is required. The 303 stainless steel construction makes it appropriate for environments where mild corrosion resistance is needed. Typical applications include HVAC control board mounting, electrical enclosure PCB supports, and other precision electronics chassis assemblies requiring inch-series 2-56 threaded hardware.

Key Features

• Female 2-56 threaded interior for standard inch-series board mounting screws
• 0.625 inch overall length provides consistent PCB standoff height
• 3/16 inch width across flats allows hex tool engagement for controlled installation
• 303 stainless steel construction meets QQ-S-763 specification for corrosion resistance
• Plain bright finish with no coating to interfere with thread engagement or grounding
• Fully threaded female bore with 3/16 inch thread depth for maximum fastener engagement

Compatibility

Designed as an OEM-style replacement or new-installation standoff for circuit board mounting applications using 2-56 inch-series threaded hardware in electronic assemblies and control panel enclosures.

Installation Notes

Installation is performed by electronics assembly technicians or control panel builders using a hex driver or nut driver sized for 3/16 inch across flats. De-energize and lock out all power to the control board or enclosure before removing or installing standoffs. Use mating 2-56 machine screws of appropriate length to avoid bottoming out in the threaded bore. Avoid over-torquing, as the 303 stainless steel hex body can deform or gall if excessive force is applied.
