Key Features & Benefits at a Glance
- Enhanced corrosion resistance with zinc-plated steel coating, extending service life in humid or demanding environments.
- Superior torque transmission and reduced cam-out thanks to the T6 Torx drive, ensuring secure fastening and minimizing tool slippage.
- High mechanical strength and durability from Rockwell B71 hardness and 60,000 psi tensile strength, preventing stripping and failure under load.
- Reliable and precise thread engagement with Class 6g coarse threads, enabling quick assembly and consistent performance.
- Broad compatibility and easy installation with the standard pan head profile, fitting common applications and providing a flush finish.
- Full threading for maximum grip along the entire 4mm length, distributing clamp force evenly for stronger joints.
- Global regulatory compliance assurance meeting ISO 7045, RoHS 3, and REACH standards, ensuring safety and environmental responsibility.
Professional Applications & Engineering Value
This M2.5 metric screw is engineered to address common industrial challenges such as vibration loosening, corrosion, and assembly inefficiency. The zinc-plated steel construction provides a protective barrier against rust and wear, ideal for electronics, automotive components, and machinery exposed to harsh conditions. The Torx T6 drive offers higher torque capabilities compared to traditional drives, reducing the risk of head damage and improving worker productivity. With a coarse thread pitch of 0.45mm and fully threaded design, it ensures rapid installation and reliable holding power in materials like metal and plastic, making it a versatile choice for high-volume manufacturing and precision assemblies where ISO 7045 compliance is critical.
Specification Summary & Compliance
This fastener adheres to precise dimensional standards, including Class 6g thread fit for consistent mating and metric thread specifications (M2.5 x 0.45mm pitch). It is manufactured in compliance with ISO 7045 for pan head screws, ensuring interchangeability and quality. Additionally, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and suitable for global supply chains.
