Electro Hardware MP411M19F16M2.5 Female Hex Standoff M2.5

Product Description

The ELECTRO HARDWARE MP411M19F16M2.5 is a female hex circuit board standoff designed to create fixed spacing between a PCB and a mounting surface or secondary board. Manufactured from nylon with a plain uncoated finish, this standoff features an M2.5 x 0.45 fully threaded female thread and a 6 mm overall length. The hexagonal body, measuring 4.5 mm across the flats, allows for wrench or tool-assisted installation and ensures consistent, non-conductive mounting. It is suited for electronics assembly and PCB mounting applications where a lightweight, electrically insulating spacer is required. Licensed electricians and electronics technicians working on control boards, automation enclosures, or instrumentation panels are the typical installers.

This standoff is used in metric fastener applications across residential and commercial electronics assemblies, industrial control panels, and HVAC or electrical equipment circuit board mounting. Its nylon construction makes it appropriate where metal-to-board contact must be avoided to prevent electrical shorts or galvanic corrosion. The fully threaded 6 mm thread depth allows a mating M2.5 screw to engage the full length of the standoff for maximum thread engagement in low-load, precision PCB mounting scenarios.

Key Features

• Female M2.5 x 0.45 metric thread, fully threaded through 6 mm thread depth
• Nylon construction provides electrical insulation and corrosion resistance
• Hexagonal body at 4.5 mm across flats allows tool-assisted tightening
• Tensile strength rated at 16,500 psi for reliable low-load PCB support
• Plain uncoated finish; no metallic coating to interfere with circuit board grounding schemes
• Meets MIL-P-17091B fastener standard

Compatibility

Designed as an OEM-style replacement or new-installation standoff for circuit board assemblies requiring M2.5 x 0.45 metric female hex standoffs with a 6 mm overall length and nylon construction.

Installation Notes

Installation is performed by electronics technicians or licensed electricians during board assembly or control panel service. Always power down and de-energize the equipment before handling any circuit board hardware. Use a correctly sized hex driver or nut driver matching the 4.5 mm across-flats dimension to avoid rounding the nylon body. Do not overtighten, as nylon fasteners have lower torque tolerance than metal equivalents and can crack or strip under excessive load.
