Professional Applications & Engineering Value

This M2.5 metric socket head cap screw is engineered to address critical sealing challenges in precision assemblies. The 18-8 stainless steel body provides excellent corrosion resistance, while the integrated silicone rubber O-ring creates a reliable seal against fluids and gases. Its fully threaded design and Class 6g thread ensure consistent clamping force, making it ideal for high-vibration environments like hydraulic systems, pneumatic equipment, and automotive components. The coarse thread pitch facilitates quick assembly, and the hex socket drive allows for high torque application without slippage. These features collectively reduce maintenance needs and enhance the durability of machinery exposed to pressures up to 1500 psi and temperatures from -80° to 400° F, delivering long-term performance in industrial settings.

Specification Summary & Compliance

This screw features a M2.5 x 0.45 mm coarse thread with Class 6g tolerance for precise fit, a fully threaded rod, and dimensions including a 6 mm length, 4.5 mm head diameter, and 2.5 mm head height.
