Electro Hardware P285M19F16256 Hex Standoff 2-56 1/8 in

Product Description

The ELECTRO HARDWARE P285M19F16256 is a female hex circuit board standoff designed to space and mount PCBs within electronic enclosures and control panels. This standoff features a 2-56 fully threaded female configuration with an overall length of 0.125 inches and a width across flats of 0.1875 inches. Machined from nylon with a plain, bright uncoated finish, it provides electrical isolation between the board and chassis. The thread depth is 0.125 inches, matching the overall length for maximum thread engagement in compact installations. With a tensile strength of 16,500 psi, this nylon standoff meets the mechanical demands of light-duty board mounting in a small form factor.

This standoff is used in PCB assembly and control board mounting applications across HVAC control panels, electrical enclosures, and other low-voltage electronic equipment. Its small hex body allows installation with standard hex drivers or pliers in tight board-level clearances. The 2-56 thread size is common in compact circuit board assemblies where space is at a premium. Electricians, controls technicians, and electronics assembly professionals working on panel builds or board-level repairs will find this standoff appropriate for standard PCB spacing tasks.

Compatibility

Designed as an OEM-style replacement or new-installation standoff for circuit board assemblies requiring a 2-56 female hex nylon standoff with a 0.125-inch overall length.

Installation Notes

Installation is performed by electronics assembly technicians or controls technicians during panel builds or PCB service. Always de-energize the control panel and discharge any capacitors before handling circuit boards or installing standoffs. Use a correctly sized hex driver or needle-nose pliers to avoid deforming the nylon hex body. Do not overtighten, as nylon fasteners are susceptible to thread stripping under excessive torque.
