Professional Applications & Engineering Value

This 1/4"-20 UNC hex head screw delivers critical engineering solutions where corrosion resistance and structural integrity are paramount. The 18-8 stainless steel composition prevents degradation in marine, chemical processing, and outdoor applications, while the coarse UNC threading provides superior grip in softer materials and faster assembly times. With 80,000 psi tensile strength and partial threading design, it effectively distributes clamping forces across joined components, preventing joint failure in heavy machinery, structural frameworks, and industrial equipment. The external hex drive ensures high torque application capability, making it ideal for maintenance operations and production lines requiring reliable fastening under vibration and dynamic loads.

Specification Summary & Compliance

Manufactured to precise inch system dimensions with Class 2A thread fit tolerance per UNC standards, ensuring consistent thread engagement. The screw meets ASME B18.2.1 manufacturing specifications for dimensional accuracy and mechanical properties. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety and material restrictions adherence. Thread configuration follows right-hand direction with 1/4"-20 UNC coarse spacing, providing optimal performance in industrial fastening applications requiring durability and reliability.
