1/2"-20 Zinc Grade 5 Steel Fine Thread Hex Bolt Cap Screws
Our Grade 5 Steel Fine Thread Hex Cap Screws are engineered for high-tensile applications where strength and reliability are paramount. These fasteners are a staple in automotive, agricultural, and industrial projects, offering a significant increase in strength over standard Grade 2 fasteners.
Each screw features a precision-formed hexagonal head designed for high-torque applications using a standard 3/4" wrench. The fine thread (20 TPI) design provides superior vibration resistance and allows for finer adjustments in sensitive assemblies. To ensure long-lasting performance in various environments, these cap screws are finished with a clear zinc plating that provides essential corrosion resistance and a professional aesthetic.
