Electro Hardware MP415M09F16M2.5 Female Hex Standoff M2.5

Product Description

The ELECTRO HARDWARE MP415M09F16M2.5 is a female hex circuit board standoff designed to create fixed spacing between a PCB and a mounting surface or a second board. The standoff is fully threaded with an M2.5 x 0.45 thread size and an 8 mm overall length that also equals the full thread depth, accepting a mating screw along the entire interior bore. The hex body measures 4.5 mm across flats, providing a clean grip point for installation with standard hex tooling. Fabricated from 303 stainless steel with a plain bright finish, it meets QQ-S-763 material standards. Licensed electricians, electronics assemblers, and control board technicians install these in low-voltage panels, HVAC control boards, and similar assemblies.

This standoff is suited for metric-threaded PCB mounting applications across residential and light commercial equipment. Typical use cases include securing control boards, relay panels, and electronic assemblies in HVAC equipment, industrial enclosures, and other applications where a corrosion-resistant metal spacer is required. The metric M2.5 x 0.45 thread pitch is standard in compact electronics and control-board assemblies. Minimum order quantity is 10 pieces per order; individual package quantity is 1.

Key Features

• Fully threaded female interior with 8 mm thread depth — accepts mating screw along full bore length
• M2.5 x 0.45 metric thread size for standard compact PCB fastening
• Hex body shape, 4.5 mm width across flats, compatible with standard hex drivers and wrenches
• 303 stainless steel construction, plain bright finish — corrosion-resistant, no additional coating
• Meets QQ-S-763 stainless steel material standard
• Length tolerance held to -0.13 to 0.13 mm for consistent board-to-board spacing

Compatibility

Designed as an OEM-style replacement or new-installation standoff for metric PCB assemblies requiring an M2.5 x 0.45 female threaded hex spacer.

Installation Notes

Installation is performed by electronics assemblers or licensed electricians working on control-board assemblies. Power down all equipment and discharge any stored voltage before accessing control boards. Use a hex driver or nut driver sized to 4.5 mm across flats to seat the standoff without over-torquing the stainless threads. Follow all applicable NEC guidelines and equipment manufacturer procedures when servicing panels or control boards.
