Electro Hardware MMF1325M0616M25 Hex Standoff M2.5x0.45

Product Description

The ELECTRO HARDWARE MMF1325M0616M25 is an aluminum male-female hex circuit board standoff designed to create precise spacing between PCBs and mounting surfaces in electronic assemblies. Threaded M2.5x0.45 on both ends, it features a male thread on one end and a female thread on the other, allowing boards to be stacked or secured at a fixed standoff height. The hexagonal body measures 4.5 mm across flats for wrench engagement. Overall length is 20.97 mm, with a body length of 17.00 mm and a male thread length of 3.97 mm. Material is aluminum grade T3 with a bright uncoated finish, conforming to QQ-A-225A Comp 2. Electronics assembly technicians and PCB installers use these fasteners in control panel and enclosure builds.

This standoff is suited for metric PCB mounting applications in industrial controls, HVAC control boards, electrical enclosures, and general electronic assemblies where M2.5 metric thread sizing is specified. The male-female configuration allows for daisy-chaining multiple boards or securing a single board to a chassis at the correct standoff height. The uncoated aluminum finish is appropriate for indoor, non-corrosive environments. Minimum order quantity is 10 pieces per order; package quantity per unit is 1.

Key Features

• M2.5x0.45 metric thread on both male and female ends for secure PCB stacking
• Overall length of 20.97 mm with body length of 17.00 mm for precise board spacing
• Hexagonal body with 4.5 mm width across flats for wrench or nut-driver installation
• Aluminum grade T3 construction - lightweight and non-magnetic
• Bright uncoated finish; meets QQ-A-225A Comp 2 material standard
• Length tolerance of -0.150 mm to 0.150 mm for consistent fit in precision assemblies

Compatibility

Designed as an OEM-style metric standoff for PCB mounting applications specifying M2.5x0.45 thread size in electronic assemblies, control boards, and enclosure hardware.

Installation Notes

Install using a hex wrench or nut driver sized for 4.5 mm across flats. Power down all circuits and discharge any stored energy before working on control boards or enclosures. Thread engagement should be confirmed on both male and female ends before torquing to avoid cross-threading in aluminum. Follow applicable electrical codes and manufacturer assembly specifications for fastener installation in energized enclosures.
