Professional Applications & Engineering Value
This 1/4"-20 UNC hex head screw in 316 Stainless Steel delivers critical corrosion resistance for demanding industrial environments including chemical processing, marine applications, and food processing equipment. The combination of 100,000 psi tensile strength and Rockwell B100 hardness ensures reliable performance under sustained mechanical stress, while the flanged design with serrations eliminates the need for separate washers and provides vibration-resistant locking. The coarse UNC thread facilitates rapid installation in various materials, and the fully threaded configuration maintains consistent clamping force across the entire fastener length. These engineering features make this external hex drive screw ideal for applications requiring both corrosion resistance and mechanical reliability.
Specification Summary & Compliance
This fastener features precision 1/4"-20 UNC coarse threads with Class 2A thread fit for consistent engagement and proper clearances. The screw measures 5/8" in length with a 9/16" flange diameter and incorporates right-hand thread direction. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance for industrial applications.
