Electro Hardware MMF1341M0916M25 Hex Standoff M2.5

Product Description

The ELECTRO HARDWARE MMF1341M0916M25 is a male-female hex circuit board standoff designed to create precise spacing and secure mechanical connections between PCBs, enclosure panels, and mounting surfaces. Machined from grade 303 stainless steel with a bright, uncoated finish, this standoff meets the QQ-S-763 fastener standard. The M2.5 x 0.45 thread size runs on both ends - male on one side, female on the other - with an overall length of 28.97 mm (approximately 1.14 inches) and a 4.5 mm hex body that accepts a standard hex driver or wrench. Electronics assembly technicians, panel builders, and control system integrators install these standoffs during PCB mounting and enclosure fabrication.

This standoff is suited for metric fastener applications in electronics assemblies, control panels, and instrumentation enclosures where corrosion resistance and dimensional consistency are required. The hex body shape allows for tool-driven installation without slippage, making it a practical choice in high-density board layouts and precision mounting applications. Its stainless steel construction makes it appropriate for environments where mild corrosion resistance is a factor.

Key Features

• Grade 303 stainless steel construction meets QQ-S-763 fastener standard
• Male-female thread configuration for stackable, through-board standoff mounting
• M2.5 x 0.45 thread size on both ends for metric fastener compatibility
• Hex body shape (4.5 mm across flats) for positive tool engagement
• Bright, uncoated finish - no coating buildup affecting thread fit
• Length tolerance of -0.150 to 0.150 mm for consistent PCB spacing

Compatibility

Designed for use with M2.5 x 0.45 metric threaded fasteners in circuit board standoff applications. Suitable as an OEM-style component in electronics assemblies, control enclosures, and instrumentation panels requiring metric hex standoffs.

Installation Notes

Install using a hex driver or open-end wrench sized to 4.5 mm across flats. Ensure mating threads and mounting holes are free of debris before installation. Do not over-torque - grade 303 stainless is resistant to corrosion but can gall under excessive torque without lubrication. Follow the equipment manufacturer's assembly specifications for board clearance and fastener seating.
