Electro Hardware MP405M19F16M2.5 Hex Standoff M2.5

Product Description

The ELECTRO HARDWARE MP405M19F16M2.5 is a female hex circuit board standoff designed to create precise, secure spacing between PCBs and mounting surfaces in electronic assemblies. Molded from nylon with a plain, uncoated finish, this standoff accepts an M2.5 x 0.45 thread and features a fully threaded 3 mm thread depth across its 3 mm overall length. The hexagonal body, measuring 4.5 mm across flats, allows for wrench engagement during installation. With a tensile strength of 16,500 psi and compliance with MIL-P-17091B, it is suited for applications where consistent standoff height and non-conductive spacing are required. Electronics technicians, PCB assemblers, and field service professionals install these standoffs in control boards and electronic enclosures across HVAC, electrical, and industrial equipment.

This standoff is used in residential and commercial electronic assemblies wherever a non-conductive, metric-threaded spacer is needed between a circuit board and a chassis or secondary board layer. Typical applications include control board mounting in HVAC equipment, electrical panel assemblies, and similar installations where maintaining board clearance prevents shorts and allows airflow. The metric M2.5 x 0.45 thread size is common in compact PCB assemblies. Minimum order quantity is 10 units; package quantity is 1.

Key Features

• Female hex body with M2.5 x 0.45 fully threaded interior for secure PCB mounting
• 3 mm overall length and 3 mm full thread depth for consistent board-to-surface spacing
• Nylon construction provides electrical non-conductivity and corrosion resistance
• Plain, uncoated finish with 4.5 mm hex width across flats for wrench engagement
• Meets MIL-P-17091B fastener standard for quality and dimensional consistency
• Tensile strength of 16,500 psi for reliable retention in light-duty assemblies

Compatibility

Designed as an OEM-style replacement or service standoff for circuit board assemblies requiring M2.5 x 0.45 metric female hex spacers with a 3 mm overall length.

Installation Notes

Installation is performed by electronics technicians or qualified service professionals. Always power down and de-energize the equipment fully before handling or replacing circuit board hardware. A hex driver or small wrench sized to 4.5 mm across flats is appropriate for engagement. Avoid over-torquing nylon standoffs, as the material is not rated for high clamping loads; hand-snug plus a minimal wrench turn is generally sufficient.
