Professional Applications & Engineering Value

These silicon bronze carriage bolts deliver critical engineering solutions where corrosion resistance and structural integrity are paramount. The square neck design prevents rotation during tightening, eliminating the need for secondary locking mechanisms in wood, marine hardware, and structural applications. The fully threaded UNC coarse thread configuration provides superior pull-out resistance in softer substrates while maintaining installation efficiency. Manufactured from silicon bronze material, these fasteners offer exceptional durability in saltwater environments, chemical processing facilities, and outdoor structures where traditional steel fasteners would rapidly deteriorate. The wide rounded head distributes clamping force effectively, minimizing surface damage to connected materials while providing reliable, long-term fastening performance in demanding industrial settings.

Specification Summary & Compliance

This 3/8"-16 UNC carriage bolt features Class 2A thread fit tolerance for optimal assembly characteristics and is manufactured in compliance with ASME B18.5 standards for dimensional accuracy and mechanical properties. The product meets RoHS 3 (2015/863/EU) compliance for restricted substance control and REACH (EC 1907/2006) compliance for chemical safety regulations. The square neck measures 0.39" width with 0.22" length, providing secure anti-rotation performance, while the 2" length and fully threaded design ensure versatile application across various industrial fastening requirements.
