Professional Applications & Engineering Value
This zinc-plated alloy steel rounded head hex screw is engineered to address critical challenges in industrial assembly, such as vibration-induced loosening and corrosion. The Class 3A UNC coarse thread provides excellent thread engagement and resistance to cross-threading, while the flanged design distributes clamping force evenly, reducing the risk of material damage. With a high tensile strength of 120,000 psi and full threading, it ensures reliable performance in machinery, automotive, and construction applications where durability and precision are paramount. The hex drive allows for efficient torque application, making it ideal for high-volume production lines and maintenance tasks.
Specification Summary & Compliance
This screw adheres to UNC coarse thread standards with Class 3A fit for precise tolerance and consistent performance. Dimensions include a 5/16"-18 thread size, 3/4" length, and 0.688" flange diameter. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory alignment for industrial use.
