Professional Applications & Engineering Value
This 5/16"-18 UNC hex head screw is engineered to address common industrial challenges, such as vibration loosening and material fatigue. Crafted from 18-8 Stainless Steel, it resists corrosion in moist or chemical-exposed settings, making it suitable for machinery, structural frameworks, and marine equipment. The coarse thread and Class 2A thread fit provide reliable grip in soft or composite materials, while the partial threading design allows for adjustable engagement depth, preventing over-tightening and ensuring even stress distribution. Ideal for heavy-duty fastening in construction, automotive, and manufacturing sectors, this screw delivers long-term performance and reduces maintenance costs.
Specification Summary & Compliance
This screw adheres to precise dimensional standards, including a Class 2A thread fit for consistent tolerance and UNC coarse threads with a diameter of 0.3125". It meets manufacturing specifications for inch system measurements and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
