Electro Hardware P289M06F16256 Hex Standoff 2-56 3/16in

Product Description

The ELECTRO HARDWARE P289M06F16256 is a female hex circuit board standoff designed to create precise spacing between PCBs and mounting surfaces in electronic assemblies. Machined from aluminum alloy with a plain (bright/uncoated) finish, this standoff accepts a 2-56 thread and measures 3/16 inches overall length with a 3/16-inch width across flats. The hex body shape allows standard hex driver installation. The full thread depth runs the complete 3/16-inch body length, providing maximum thread engagement in a compact form factor. It meets the QQ-A-225A Comp 2 fastener standard and is manufactured to inch measurement conventions with a length tolerance of -0.005 to 0.005 inches.

This standoff is used in residential and commercial electronic control board assemblies, instrument panels, and low-voltage control enclosures. Typical applications include PCB stacking, board-to-chassis mounting, and standoff spacer configurations in HVAC control boards, electrical enclosures, and similar equipment requiring precise, repeatable board separation. Installation is performed by electronics assemblers, controls technicians, or electrical tradespeople during board assembly or field service. Minimum order quantity is 25 pieces.

Key Features

• Female 2-56 internal thread with full 3/16-inch thread depth for maximum engagement
• Hex body profile for tool-assisted installation with standard hex drivers or wrenches
• Aluminum construction with plain bright finish — lightweight and non-magnetic
• Meets QQ-A-225A Comp 2 fastener standard
• Compact 3/16-inch OAL suits tight PCB spacing requirements
• Length tolerance of -0.005 to 0.005 inches for consistent board standoff height

Compatibility

Designed as an OEM-style replacement or assembly component for circuit boards requiring 2-56 female hex standoffs in inch-measurement fastener configurations.

Installation Notes

Installation is performed by electronics or controls technicians using a hex driver or small wrench sized to the 3/16-inch width across flats. De-energize and discharge all circuits before working on any control board assembly. Follow applicable NEC guidelines and equipment manufacturer service procedures when replacing or installing control board hardware. Avoid overtightening to prevent thread stripping in the aluminum body.
