Electro Hardware P297M12F21256 Hex Standoff 2-56

Product Description

The ELECTRO HARDWARE P297M12F21256 is a female hex circuit board standoff designed for use in printed circuit board assemblies where secure, repeatable board-to-board or board-to-chassis spacing is required. This standoff features a 2-56 fully threaded female thread, an overall length of 0.3125 inches (5/16 inches), and a hex body width across flats of 0.1875 inches (3/16 inches). Constructed from steel with a clear zinc chromate finish, it meets ASTM B633 Type 1 and QQ-S-633 finish standards. Thread depth runs the full 5/16 inch body length. Electronics assemblers, electrical technicians, and OEM production technicians install this hardware in control boards and enclosure mounting applications.

This standoff is suited for residential and commercial electronic control board assemblies, PCB mounting racks, and enclosure panel builds. It is appropriate wherever a 2-56 threaded female hex standoff is specified for maintaining fixed separation between boards or securing a board to a chassis surface. The compact hex body accommodates standard nut drivers and hex wrenches in tight board layouts.

Key Features

• 2-56 fully threaded female thread, 5/16 inch thread depth
• Overall length of 5/16 inches (0.3125 inches) for precise board spacing
• Hex body profile, 3/16 inch width across flats, compatible with standard nut drivers
• Steel construction with clear zinc chromate finish per ASTM B633 Type 1 and QQ-S-633
• Inch measurement system, Material Grade 2 fastener

Compatibility

Designed as an OEM-style replacement or new-installation standoff for circuit board assemblies requiring a 2-56 female hex standoff with a 5/16 inch overall length in inch-measurement fastener applications.

Installation Notes

Installation is performed by electronics technicians or electricians during board assembly or field service. Power down and de-energize all circuits before working on any control board assembly. Use a nut driver or hex wrench sized to 3/16 inch across flats to seat the standoff without over-torquing the threaded body. Follow applicable NEC guidelines and equipment manufacturer procedures when replacing control board hardware in energized enclosures.
