Electro Hardware MP445M19F16M2.5 Hex Standoff M2.5

Product Description

The ELECTRO HARDWARE MP445M19F16M2.5 is a female hex circuit board standoff designed to mount and space printed circuit boards within electronic enclosures and assemblies. Made from nylon with a plain, uncoated finish, this standoff accepts an M2.5 x 0.45 thread and provides a 4.8 mm thread depth for secure fastener engagement. The overall length is 23.0 mm, and the hex body measures 4.5 mm across the flats for easy installation with standard hex tooling. It meets the MIL-P-17091B fastener standard. Electronics technicians and OEM assembly workers install these standoffs in control boards, enclosure panels, and PCB mounting applications where non-conductive spacing is required.

This standoff is suited for use in low-voltage circuit board assemblies across commercial and residential electronics, HVAC control panels, and industrial enclosures. The nylon construction provides electrical isolation between the board and mounting surface, making it appropriate wherever a non-metallic spacer is specified. The metric M2.5 x 0.45 thread size is common in compact PCB layouts. Sold individually with a minimum order quantity of 10 units per order.

Key Features

• Female M2.5 x 0.45 internal thread with 4.8 mm thread depth
• 23.0 mm overall length provides consistent board standoff height
• Hex body at 4.5 mm across flats allows wrench or socket installation
• Nylon construction provides electrical isolation and corrosion resistance
• Plain, uncoated finish suitable for general indoor PCB assembly
• Meets MIL-P-17091B fastener standard

Compatibility

Designed as an OEM-style replacement or new-installation standoff for printed circuit board assemblies requiring M2.5 x 0.45 metric female hex spacers with a 23.0 mm overall length.

Installation Notes

De-energize all equipment fully before servicing circuit board assemblies. Use an appropriately sized hex driver or wrench on the 4.5 mm flats to avoid stripping the nylon body. Do not overtighten fasteners into the threaded bore, as nylon has a tensile strength of 16,500 psi and can crack under excessive torque. Follow applicable electronic assembly guidelines and enclosure manufacturer specifications when determining standoff placement and fastener length.
