Professional Applications & Engineering Value
This 10-24 x 1/2" stainless steel rounded head screw is engineered to address common industrial challenges, such as fluid leakage and tampering in high-pressure systems. The 18-8 stainless steel material offers excellent corrosion resistance, while the Buna-N rubber O-ring creates a tight seal against liquids and gases, making it ideal for pneumatic, hydraulic, and automotive applications. The tamper-resistant Torx drive (T25) enhances security in public or restricted areas, and the fully threaded UNC design with Class 3A fit ensures reliable performance in assemblies requiring precise tolerance. By combining durability with regulatory compliance, this screw reduces maintenance costs and improves operational safety in demanding environments.
Specification Summary & Compliance
This screw features a 10-24 UNC coarse thread with Class 3A thread fit for high precision, and it is manufactured to meet ASME B18.3 specifications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use. The dimensions include a head diameter of 0.361" and length of 1/2", with full threading for consistent application.
