Professional Applications & Engineering Value

Engineered specifically for marine applications and harsh industrial environments, this silicon bronze hex nut delivers exceptional performance where corrosion resistance is critical. The extra wide profile distributes clamping force more effectively, reducing surface damage and maintaining joint integrity in heavy-duty fastening applications. The UNC coarse thread with Class 2B fit provides reliable engagement even in vibrating conditions, while the external hex drive ensures compatibility with standard installation tools. This 5/16"-18 hex nut solves common challenges in saltwater exposure, chemical processing, and outdoor applications where standard steel fasteners would rapidly deteriorate.

Specification Summary & Compliance

This silicon bronze hex nut features 5/16"-18 UNC coarse threading with Class 2B thread fit per standard inch specifications. The dimensional profile measures 9/16" width and 19/64" height with an extra wide profile for enhanced performance. Manufacturing complies with industry standards for external hex drive fasteners and maintains full compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, including exemption 6(a)-I for lead as an alloying element.
