• Optimized for high-torque assembly with a large 1/2" hex drive and standard socket head profile, allowing for efficient installation and removal.
• Versatile partial threading with a 1 3/4" minimum thread length on a 5" long body, offering flexibility in clamping and positioning.
• Broad industrial compatibility with 5/8"-11 UNC coarse threads and right-hand direction, conforming to common standards for easy integration.
• Compliance with strict environmental regulations, being RoHS 3 and REACH compliant for safe use in regulated industries.

Professional Applications & Engineering Value

This 316 stainless steel socket head cap screw is engineered to solve critical challenges in corrosive and high-stress environments, such as chemical processing, marine equipment, and food machinery. Its passivated finish significantly boosts resistance to pitting and oxidation, extending service life where moisture and chemicals are present. The Class 3A thread fit and coarse UNC threads ensure rapid assembly with high vibration resistance, reducing maintenance downtime. With a 1/2" hex drive, it handles substantial torque without stripping, making it ideal for heavy-duty industrial fasteners in construction, automotive, and machinery assembly. The partially threaded design allows for precise unthreaded shank use in shear applications, providing reliable engineering value by combining strength, corrosion resistance, and compliance for long-term performance.

Specification Summary & Compliance

This screw adheres to precise dimensional standards, including a Class 3A thread fit for superior tolerance and UNC coarse thread specifications (5/8"-11). It is manufactured from 316 stainless steel with a passivated finish, ensuring consistent quality. Compliance is confirmed with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its suitability for environmentally conscious industrial applications without hazardous substances.
