Professional Applications & Engineering Value
This 18-8 stainless steel hex head screw is engineered to address common industrial challenges, such as corrosion-induced failure and vibration loosening. The UNC coarse thread and partial threading design enhance grip in softer materials and allow for unthreaded sections to bear loads without damaging threads, making it ideal for machinery, structural frames, and equipment assemblies. Its external hex drive ensures quick installation with standard wrenches, boosting productivity in maintenance and manufacturing. The high tensile strength and corrosion-resistant properties provide long-term durability in demanding environments, reducing downtime and replacement costs for B2B clients.
Specification Summary & Compliance
The screw features precise Class 2A thread fit and UNC coarse threading with a 1/4"-20 size and 3/4" minimum thread length, adhering to ASME B18.2.1 standards for dimensional consistency. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory alignment for industrial use.
