Professional Applications & Engineering Value
Engineered for demanding industrial environments, these 1/4"-20 UNC hex head screws in 316 stainless steel provide critical solutions where corrosion and high stress are primary concerns. The coarse thread design prevents cross-threading in high-vibration settings like heavy machinery and structural frameworks, while the fully threaded body ensures uniform clamping force across the entire joint. The external hex drive allows for high torque application with common tools, making them ideal for assembly lines, marine equipment, chemical processing plants, and infrastructure projects requiring ASME B18.2.1 compliance. This combination of material durability and precision engineering delivers long-term reliability in critical fastening applications.
Specification Summary & Compliance
This hex head screw features a 1/4"-20 UNC thread with Class 2A fit tolerance, ensuring precise thread engagement and interchangeability. Manufacturing and dimensional standards strictly adhere to ASME B18.2.1. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally conscious and regulated industrial markets.
