Professional Applications & Engineering Value
This Grade 5 hex head screw is engineered to address critical challenges in heavy-duty industrial settings, such as construction, machinery assembly, and equipment manufacturing. Its zinc plated steel construction provides robust protection against corrosion, which is essential for outdoor or humid environments where rust can compromise structural integrity. The 3/4"-16 UNF fine thread and Class 2A fit deliver precise engagement, reducing the likelihood of cross-threading and ensuring stable connections in dynamic loads. With a tensile strength of 120,000 psi and full threading, it supports high-stress applications by distributing force evenly, making it a reliable choice for securing heavy components in automotive, industrial, and infrastructure projects where durability and compliance with ASME standards are paramount.
Specification Summary & Compliance
This fastener adheres to Class 2A thread tolerance for consistent fit and is manufactured in accordance with ASME B18.2.1 and SAE J429 specifications. It meets RoHS 3 (2015/863/EU) compliance, ensuring it is free from hazardous substances, and is suitable for use in regulated industries requiring environmental and safety standards.
