Electro Hardware P333M09F16256 Hex Standoff 2-56 7/8in Ss

Product Description

The ELECTRO HARDWARE P333M09F16256 is a female hex circuit board standoff designed to create fixed, measured separation between stacked PCBs or between a circuit board and a mounting surface. Threaded internally at 2-56, this fastener accepts a mating male screw on the board side and provides a secure threaded female socket for the next board or cover panel. The hex body profile at 3/16 inches across flats allows standard hex drivers or wrenches for consistent torque. Machined from grade 303 stainless steel with a plain bright finish, it meets the QQ-S-763 specification for stainless fasteners. Electronics assemblers, control board technicians, and panel builders install these standoffs during board assembly and enclosure builds.

This standoff is suited for use in electronic control assemblies where consistent board-to-board or board-to-chassis spacing is required. Typical applications include HVAC control boards, electrical enclosure panel assemblies, and industrial PCB stacking. The 7/8 inch overall length and 3/16 inch thread depth make it appropriate for light-gauge board layouts using 2-56 hardware. Its plain stainless finish is compatible with indoor and light industrial environments where mild corrosion resistance is needed without additional coating.

Key Features

• Female internal thread at 2-56 for standard small-fastener compatibility
• 7/8 inch overall length provides consistent PCB standoff spacing
• 3/16 inch hex body width across flats allows wrench or driver installation
• Grade 303 stainless steel construction meets QQ-S-763 fastener specification
• Plain bright finish — no coating to interfere with close-tolerance fits
• Length tolerance held to plus or minus 0.005 inches for precision assemblies

Compatibility

Designed as an OEM-style replacement or new-installation standoff for circuit board assemblies using 2-56 threaded hardware and requiring 7/8 inch board separation with a hex body profile.

Installation Notes

Installation is performed by electronics assemblers and control board technicians using a hex wrench or nut driver sized to 3/16 inches across flats. Always de-energize and discharge any board or assembly before installing or removing standoffs. Avoid over-torquing on small 2-56 threads, as stainless fasteners are susceptible to galling if driven dry at high speed. Follow applicable assembly documentation and IPC standards for PCB hardware installation practices.
