Professional Applications & Engineering Value

These 3/8"-16 UNC hex head screws manufactured from 651 silicon bronze address critical corrosion and strength challenges in marine construction, chemical processing, and offshore equipment. The coarse thread design provides superior pull-out resistance in soft materials like wood and composites, while the external hex drive facilitates high-torque installation without stripping. With fully threaded construction and 70,000 psi tensile strength, these fasteners maintain structural integrity in high-vibration environments where corrosion resistant fasteners are essential for long-term reliability and reduced maintenance costs.

Specification Summary & Compliance

Manufactured to ASME B18.2.1 specifications with Class 2A thread fit tolerance for precise engagement. The UNC coarse thread (3/8"-16) ensures compatibility with standard components. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe usage across regulated industries.
