Electro Hardware MMF1307M0916M25 Hex Standoff M2.5

Product Description

The ELECTRO HARDWARE MMF1307M0916M25 is a male-female hex circuit board standoff designed to create precise spacing between stacked PCBs or between a circuit board and a mounting surface. Machined from 303 stainless steel with a bright uncoated finish, it meets the QQ-S-763 fastener standard. The standoff features an M2.5 x 0.45 thread on both the male and female ends. Overall length is 11.97 mm (0.471 inches), body length is 8.00 mm (0.315 inches), and thread length is 3.97 mm (0.156 inches). Width across the hex flats is 4.50 mm (0.177 inches). Electronics technicians, PCB assemblers, and field service professionals install these standoffs in control boards, panel assemblies, and electronic enclosures.

This standoff is suited for metric PCB assembly applications where stainless steel durability and corrosion resistance are required. Typical use cases include control board mounting in HVAC equipment, electrical panels, and industrial enclosures where vibration resistance and reliable board-to-board spacing are needed. The male-female configuration allows multiple standoffs to be threaded together or used to attach a board to a tapped surface. Minimum order quantity is 2 pieces; each package contains 1 piece.

Compatibility

Designed as a metric M2.5 x 0.45 hex standoff for use in PCB assemblies, electronic enclosures, and control board mounting applications requiring stainless steel hardware conforming to QQ-S-763.

Installation Notes

Install and remove using an appropriately sized hex wrench or nut driver sized for 4.50 mm flats. Power down and discharge all capacitors in the assembly before handling circuit boards or fasteners. Avoid over-torquing, as small-diameter metric threads on stainless steel are susceptible to galling. Follow applicable assembly standards for your equipment type during installation.
