Professional Applications & Engineering Value
This Black-Oxide 18-8 Stainless Steel screw is engineered to address common industrial challenges, such as corrosion and mechanical failure. The rounded truss head provides a low-profile, wide bearing surface that distributes load effectively, reducing surface damage and improving stability in assemblies. With fully threaded UNC coarse spacing and Class 2A thread fit, it ensures quick, secure fastening in materials like metal and plastic, minimizing the risk of stripping. The Phillips No. 2 drive allows for efficient installation with standard drivers, enhancing productivity in manufacturing, electronics, and automotive sectors. Its high tensile strength and hardness make it suitable for applications requiring reliable, long-term performance under vibration and load, while the corrosion-resistant coating extends service life in humid or chemical-exposed environments.
Specification Summary & Compliance
This screw features precise inch system measurements, including a thread size of 8-32 UNC with coarse spacing and Class 2A thread fit for accurate tolerances. It is manufactured in compliance with ASME B18.6.3 specifications, ensuring dimensional consistency and reliability. Additionally, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from restricted substances and safe for industrial use.
