Electro Hardware MP417M19F16M3 Hex Standoff M3x0.5 Nylon

Product Description

The ELECTRO HARDWARE MP417M19F16M3 is a female hex circuit board standoff designed to create precise, secure spacing between PCBs and mounting surfaces in electronic assemblies. Machined from nylon with a plain (uncoated) finish, this standoff features an M3 x 0.5 internal thread, a fully threaded 9 mm thread depth, and a hex body measuring 4.5 mm across the flats. The overall length is 9 mm (approximately 0.354 inches). Licensed electricians, electronics technicians, and PCB assembly professionals install this type of hardware during panel builds, control board mounting, and enclosure work where metallic standoffs would create unwanted conductivity or grounding paths.

This standoff is suited for metric-threaded circuit board mounting applications in both residential and commercial control panels, industrial enclosures, and electronic device assemblies. The nylon construction makes it appropriate for environments where electrical isolation between the board and the chassis is required. It meets MIL-P-17091B standards, making it a fit for applications where military-spec nylon fastener compliance is specified. Minimum order quantity is 10 pieces; individual package quantity is 1.

Key Features

• Female M3 x 0.5 thread on both ends for secure PCB-to-surface fastening
• Fully threaded at 9 mm thread depth — no unthreaded shank to limit engagement
• Nylon construction provides electrical isolation and corrosion resistance
• Hex body (4.5 mm across flats) allows wrench or socket installation and removal
• Meets MIL-P-17091B fastener standard for nylon hardware
• Plain (bright/uncoated) finish — no metallic plating that could flake or contaminate boards

Compatibility

Designed as an OEM-style replacement or new-installation component for metric M3 x 0.5 threaded circuit board standoff applications requiring nylon, electrically isolating hardware.

Installation Notes

Installation is typically performed by electronics technicians or licensed electricians during panel assembly or PCB mounting. De-energize and lock out all power to the assembly before installing or replacing standoffs. Use an appropriately sized hex driver or wrench matching the 4.5 mm across-flats dimension to avoid stripping the nylon body — do not over-torque, as nylon threads are more susceptible to damage than metal. Follow applicable enclosure and panel-wiring codes such as NFPA 70 (NEC) for finished electrical assemblies.
