Coastal and Floodplain Construction Inspector's Practice Exam

The standard that governs the coated weights for zinc-coated fasteners is ASTM A 153. This specification specifically addresses the requirements for coatings on iron and steel hardware, including fasteners, that are used in various applications and environments. ASTM A 153 outlines the required thickness of the zinc coating to ensure adequate corrosion resistance, which is vital for maintaining the integrity and longevity of the fasteners in service.

Understanding this standard is crucial for inspectors as it ensures compliance with quality requirements for coated fasteners, impacting the performance of the construction project. While other standards like ASTM A 123 focus on hot-dip galvanizing for structural products, and ASTM B 695 pertains to zinc coatings applied by other means, neither aligns specifically with the requirements for zinc-coated fasteners as outlined in ASTM A 153. Hence, it is essential to reference the correct standard to ensure the appropriate specifications are met.
