Professional Applications & Engineering Value
This 1/4"-20 UNC Hex Head Screw in 316 Stainless Steel is engineered to solve critical challenges in corrosive and high-stress environments. The coarse thread design ensures rapid installation and superior holding power in soft materials or where vibration is a concern, while the partial threading offers an unthreaded grip length for enhanced shear strength. Its external hex drive allows for high-torque application with standard tools, making it a versatile choice for industrial machinery, marine equipment, chemical processing plants, and structural fabrications. The inherent corrosion resistance of 316 stainless steel significantly extends service life, reducing maintenance costs and downtime in aggressive operational settings.
Specification Summary & Compliance
This screw adheres to Class 2A thread fit tolerances and is manufactured to the dimensional requirements of ASME B18.2.1. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for use in environmentally conscious and regulated industries.
