Electro Hardware P405M19F16256 Hex Standoff 2-56 2in Nylon

Product Description

The ELECTRO HARDWARE P405M19F16256 is a female hex circuit board standoff with a 2-56 thread size and a 2-inch overall length. Made from nylon with a plain, uncoated finish, this standoff provides a threaded female receptacle on each end to secure circuit boards at a fixed distance from a mounting surface. The hexagonal body measures 3/16 inches across flats, allowing standard wrench engagement during installation. With a tensile strength of 16,500 psi and compliance with MIL-P-17091B, it meets military-grade material standards for nylon fasteners. Electronics assemblers and PCB technicians use this standoff in both production and field repair applications.

This standoff is designed for use in printed circuit board assemblies where a consistent, non-conductive spacing solution is required. The nylon construction makes it well suited for low-voltage electronics enclosures, control panels, and PCB mounting applications where electrical isolation between the board and chassis is necessary. It is a common hardware component in industrial controls, HVAC control boards, and electronic equipment assemblies. The 2-56 thread size fits standard 2-56 machine screw hardware used throughout the electronics industry.

Key Features

• Female 2-56 thread on both ends for standard machine screw compatibility
• 2-inch overall length provides fixed PCB standoff spacing
• Hex body at 3/16 inches across flats allows wrench-driven installation
• Nylon construction provides electrical isolation between board and mounting surface
• Plain, uncoated finish with no metallic coating to interfere with electronics
• Meets MIL-P-17091B fastener standard for nylon hex standoffs

Compatibility

Designed as an OEM-style replacement or standard-use component for printed circuit board assemblies requiring 2-56 female hex standoffs with a 2-inch overall length in nylon construction.

Installation Notes

Installation is typically performed by electronics technicians or PCB assembly professionals using a nut driver or open-end wrench sized for 3/16-inch hex flats. Power down and de-energize any circuit board assembly before installing or removing standoffs. Avoid overtightening nylon standoffs, as the material is susceptible to thread damage under excessive torque. Confirm thread engagement depth does not exceed the 3/16-inch thread depth specification to avoid stripping the internal threads.
