Electro Hardware MMF1319M0916M25 Hex Board Standoff M2.5

Product Description

The ELECTRO HARDWARE MMF1319M0916M25 is a male-female hex circuit board standoff designed to create fixed spacing between stacked PCBs or between a board and a chassis. The standoff features M2.5 x 0.45 threading on both ends - male on one end, female (threaded bore) on the other - allowing boards to be threaded and locked at a precise height. The overall length is 17.97 mm, with a 14.00 mm hex body and a 4.50 mm width across flats. Machined from 303 grade stainless steel with a bright, uncoated finish, this standoff meets QQ-S-763 material standards. Electronics assemblers and field service technicians install these during PCB assembly and chassis builds.

This standoff is used in control board assemblies, embedded electronics enclosures, and instrumentation panels where precise, repeatable board-to-board or board-to-chassis spacing is required. The hex body shape allows installation and removal with standard hex drivers or wrenches, making it well suited for both initial assembly and field service work. Typical applications include industrial control panels, HVAC control board stacks, and commercial electronics chassis construction.

Key Features

• Male-female thread configuration - M2.5 x 0.45 on both ends for stackable PCB mounting
• 303 grade stainless steel construction - corrosion resistant and suitable for indoor and light-duty industrial environments
• Bright, uncoated finish - meets QQ-S-763 fastener material standard
• Hex body shape - 4.50 mm width across flats for wrench or driver installation
• Overall length of 17.97 mm with a body length of 14.00 mm - consistent, accurate board spacing
• Length tolerance of -0.150 to 0.150 mm - tight dimensional control for precision assemblies

Compatibility

Designed for use in PCB and chassis assemblies requiring M2.5 x 0.45 metric threaded standoffs with a hex body profile. Verify thread size, overall length, and body length against the target board hole pattern and spacing requirement before ordering.

Installation Notes

Electronics assemblers and field technicians install hex standoffs using a hex driver or open-end wrench sized to 4.50 mm across flats. Always power down and de-energize the equipment fully before working inside any control enclosure or panel. Avoid over-torquing - stainless M2.5 hardware is susceptible to galling if driven with excessive force. Hand-start threads before applying a tool to prevent cross-threading.
