3361 - 134209 - Silicon Bronze Cap Screw Hex Socket- 5/16 - 18 UNC x 3/4"

Unbrako style Hex Socket Cap Screw with a smooth cylindrical head and internal socket hexagonal drive suitable for structural applications, machinery assembly, and component fabrication Perfect for use in tight spaces where larger head types won't fit, with the added advantage of a precise torque application and secure engagement, reducing the risk of stripping or slippage. Ideal for equipment assembly, structural repairs, and installations requiring non-ferrous fastening solutions that maintain integrity over extended service periods. Manufactured from silicon bronze, it provides outstanding resistance to seawater corrosion, atmospheric oxidation, and chemical exposure throughout its operational lifespan without requiring protective coatings or maintenance interventions — critical for marine installations, offshore equipment, and coastal infrastructure.
