S-99437A125 M2.5 Press-Fit Nuts

Key Features & Benefits at a Glance

• Secure panel retention in thin materials down to 1mm minimum thickness, preventing loosening in vibration-prone environments.
• High corrosion resistance from zinc-plated steel construction, ensuring long-term reliability in harsh industrial or electrical settings.
• Quick, tool-free installation with press-fit hex design, reducing assembly time and labor costs.
• Precision Class 6H thread fit for consistent mating with M2.5 bolts, minimizing cross-threading and ensuring reliable torque performance.
• Optimized for 4.5mm drill bits, providing a snug fit that eliminates the need for additional fastening hardware.
• RoHS 3 compliance meeting environmental regulations for use in electronics and consumer goods.
• Right-hand coarse threading (0.45mm pitch) for rapid installation and high resistance to vibrational loosening.

Professional Applications & Engineering Value

These M2.5 press-fit nuts are engineered to solve common challenges in electrical enclosures, control panels, and lightweight assemblies where space and material thickness are constrained. The zinc-plated steel offers a durable barrier against oxidation and corrosion, critical for maintaining electrical integrity in humid or industrial atmospheres. The hex press-fit head ensures anti-rotation stability during installation, while the coarse metric thread provides robust engagement with mating components, reducing the risk of strip-out in thin 1mm panels. By specifying a 4.5mm drill bit, engineers achieve a precise interference fit that eliminates the need for welding or adhesives, streamlining production in high-volume metric system applications.

Specification Summary & Compliance

This nut conforms to metric coarse thread standards with M2.5 size, 0.45mm pitch, and Class 6H thread fit for consistent dimensional accuracy. Manufactured from zinc-plated steel with a hex head (5.5mm width, 2.1mm height), it is designed for right-hand threading and press-fit installation in panels ≥1mm thick using a 4.5mm drill. The product is RoHS 3 (2015/863/EU) compliant, ensuring adherence to hazardous substance restrictions for global markets.
