Electro Hardware MP425M19F16M3 Female Hex Standoff M3

Product Description

The ELECTRO HARDWARE MP425M19F16M3 is a female hex circuit board standoff designed to create precise spacing between PCBs or between a PCB and a mounting surface. Manufactured from nylon with a plain uncoated finish, this standoff accepts M3 x 0.5 threaded fasteners and is fully threaded through its 13 mm overall length. The hexagonal body profile measures 4.5 mm across the flats, allowing for wrench or nut-driver installation. It meets MIL-P-17091B standards and is suited for electronics assembly and circuit board mounting applications where a non-conductive, lightweight spacer is required.

This standoff is used in circuit board stacking, panel-mount PCB installations, and electronics enclosure builds across industrial, commercial, and defense-adjacent applications. Its nylon construction makes it appropriate in assemblies where electrical isolation between mounting hardware and the board is a priority. Electronics assemblers, field service technicians, and PCB enclosure builders are the typical end users. The metric M3 x 0.5 thread size is common in consumer electronics, instrumentation panels, and control boards found in HVAC, electrical, and industrial control equipment.

Key Features

• Female M3 x 0.5 thread, fully threaded through 13 mm depth for secure fastener engagement
• Nylon construction provides electrical isolation and corrosion resistance without added weight
• Hexagonal body at 4.5 mm across flats allows standard wrench or nut-driver installation
• Plain uncoated finish; no metallic coating to interfere with non-conductive requirements
• Meets MIL-P-17091B fastener standard for nylon threaded components
• Tensile strength rated at 16,500 psi, suitable for typical PCB mounting loads

Compatibility

Designed for use with M3 x 0.5 threaded screws and bolts in circuit board standoff and stacking applications. Compatible with PCB mounting configurations requiring a nylon, non-conductive hex standoff at 13 mm overall length.

Installation Notes

Installation is typically performed by electronics assemblers or technicians during board mounting or enclosure builds. Power down and de-energize any circuit board assembly before installing or replacing standoffs. Use a nut driver or open-end wrench sized for 4.5 mm across flats to avoid over-torquing the nylon body, which can crack or strip under excessive force. Follow applicable assembly standards and any relevant IPC guidelines for PCB mounting hardware.
