Stainless 316 HHCS, Fully Threaded (Inch), ASTM F593
Our Stainless Steel 316 Heavy Hex Head Cap Screws, Fully Threaded (Inch series) manufactured to ASTM F593 are premium corrosion‑resistant fasteners designed for demanding industrial and outdoor applications. Produced from Type 316 stainless steel, these cap screws offer superior resistance to chlorides, chemicals, saltwater, and harsh environmental conditions compared to standard 304 stainless fasteners.
The heavy hex head provides a larger bearing surface and increased wrenching area than standard hex heads, allowing improved torque control and load distribution in high‑stress joints. The fully threaded design ensures continuous thread engagement along the entire shank, making these fasteners ideal for assemblies requiring maximum adjustability, consistent clamp load, and full thread contact through the joint. With inch‑series UNC threading, ASTM F593 fully threaded 316 HHCS are commonly used in marine construction, processing equipment, structural assemblies, and corrosive‑environment installations.
Engineered for durability and performance, ASTM F593 Stainless 316 Fully Threaded Heavy Hex Cap Screws are widely used in marine hardware, chemical processing facilities, wastewater treatment systems, food and beverage operations, and outdoor structural applications. The fully threaded configuration provides flexibility in nut placement and uniform load distribution, while the heavy hex head supports higher torque values and improved joint stability. Available in a wide range of inch diameters and lengths, these fasteners deliver dependable mechanical strength and long service life where corrosion resistance and precision fastening are critical.
