Professional Applications & Engineering Value

This 3/4"-10 UNC hex head screw delivers critical engineering solutions where corrosion resistance and structural integrity are paramount. Manufactured from 316 Stainless Steel with ASTM Grade B8M certification, it effectively combats pitting and stress corrosion cracking in marine, chemical processing, and offshore applications. The coarse thread design and external hex drive enable quick assembly and high torque application, minimizing installation time while preventing loosening under dynamic loads. With a partially threaded shank, it provides precise clamping force distribution across the 3" grip length, making it ideal for flanges, structural connections, and heavy machinery where vibration and thermal cycling are common challenges.

Specification Summary & Compliance

This heavy-duty hex bolt features precise Class 2A thread fit per UNC standards, ensuring consistent engagement and interchangeability. Manufacturing adheres to ASTM A193 specifications for high-temperature service, with material certification to ASTM Grade B8M. The fastener complies with industry standards for dimensional accuracy, including the 1 3/4" thread length and 4 3/4" overall length. While specific RoHS/REACH declarations require supplier verification, the 316 Stainless Steel composition typically meets environmental compliance requirements for industrial components.
