Electro Hardware MP435M19F16M2.5 Hex Standoff M2.5

Product Description

The ELECTRO HARDWARE MP435M19F16M2.5 is a female hex circuit board standoff designed to create precise, measured spacing between PCBs and mounting surfaces in electronic assemblies. Manufactured from nylon with a plain, uncoated finish, this standoff uses an M2.5 x 0.45 metric thread and provides an overall length of 18.0 mm with full thread depth throughout the body. The hexagonal body profile, measuring 4.5 mm across the flats, allows for standard wrench or socket installation. With a tensile strength of 16,500 psi and compliance to MIL-P-17091B, it meets military specification requirements for nylon plastic fasteners used in circuit board and panel mounting applications.

This standoff is suited for use in control board assemblies, industrial electronics, HVAC control panels, and other applications where non-conductive plastic hardware is required to mount or stack PCBs. The nylon construction provides electrical isolation between the board and chassis. It is typically installed by electronics assemblers, field service technicians, and control panel builders working on low-voltage or sensitive PCB mounting scenarios where metal standoffs would create unwanted conductivity or grounding issues.

Key Features

• M2.5 x 0.45 metric thread, fully threaded to the full 18.0 mm body length
• Nylon construction provides electrical isolation and corrosion resistance
• Hexagonal body at 4.5 mm across flats for wrench-assisted installation
• Plain, uncoated finish suitable for indoor and enclosed panel environments
• Meets MIL-P-17091B military specification for nylon plastic fasteners
• Tensile strength of 16,500 psi for reliable board retention

Compatibility

Designed as an OEM-style replacement or new-installation standoff for circuit board mounting applications requiring M2.5 x 0.45 metric thread female hex nylon hardware conforming to MIL-P-17091B standards.

Installation Notes

Install using a wrench or socket sized to 4.5 mm across the flats. Nylon fasteners are sensitive to overtorquing — hand-tighten and apply only light tool force to avoid thread stripping or body cracking. Ensure mating screws match the M2.5 x 0.45 thread specification before assembly. Power down all circuits and discharge any stored energy in the board assembly before servicing or replacing standoffs in live panels.
