Electro Hardware MP433M19F16M2.5 Hex Standoff M2.5

Product Description

The ELECTRO HARDWARE MP433M19F16M2.5 is a female hex circuit board standoff designed to create measured spacing between PCBs, mounting panels, and enclosures in electronic assemblies. Machined from nylon with a plain, bright uncoated finish, this standoff accepts M2.5 x 0.45 metric thread and features a full 17 mm thread depth throughout its 17 mm overall length. The hex body measures 4.5 mm across the flats, allowing standard hex drivers to seat and torque the fastener without slipping. At a tensile strength of 16,500 psi, this nylon standoff provides reliable mechanical support in lightweight, non-conductive mounting applications. It meets MIL-P-17091B standards, making it appropriate for builds where documented material compliance is required.

This standoff is used in residential and commercial electronic control assemblies, HVAC control boards, PCB panel mounts, and general-purpose enclosure builds where electrical isolation between metal surfaces and circuit boards is necessary. Electricians, electronic technicians, and OEM assembly technicians install these as part of structured PCB mounting configurations. The fully threaded female bore allows a mating machine screw to thread in from either end, supporting stacked board configurations or panel-to-board spacing setups. Metric dimensioning makes this part compatible with M2.5-standard hardware commonly found in imported equipment and modern control systems.

Key Features

• Female hex body with M2.5 x 0.45 internal thread for standard metric fastener compatibility
• 17 mm overall length with full 17 mm thread depth — fully threaded bore
• 4.5 mm width across flats for positive hex driver engagement
• Nylon construction provides electrical isolation and corrosion resistance
• Plain, bright uncoated finish — no metallic coating to interfere with non-conductive applications
• Meets MIL-P-17091B standard for documented compliance builds

Compatibility

Designed as a standard metric M2.5 x 0.45 female hex standoff suitable for PCB mounting, panel spacer, and enclosure assembly applications requiring nylon, non-conductive hardware conforming to MIL-P-17091B.

Installation Notes

Electronic technicians and electricians install these standoffs using a standard hex driver or nutdriver sized for 4.5 mm across flats. Power down and de-energize all circuits before installing or removing standoffs on live control boards. Avoid over-torquing nylon hardware, as nylon threads are more susceptible to stripping than metal equivalents. Follow applicable assembly standards and enclosure codes for your jurisdiction when integrating these into control panel builds.
