Fractional Sizes 18-8 Stainless Steel Socket Head Cap Screw
Fractional Sizes 18-8 Stainless Steel Socket Head Cap Screws are precision-engineered fasteners designed for high-strength, corrosion-resistant performance in demanding environments. Manufactured from premium 18-8 stainless steel (containing approximately 18% chromium and 8% nickel), these socket head cap screws deliver excellent durability, clean aesthetics, and long-term reliability across industrial, commercial, and marine applications.
Known for their high tensile strength and superior resistance to rust and oxidation, 18-8 stainless steel socket head cap screws are ideal for both indoor and outdoor installations where moisture, humidity, or mild chemicals are present.
Key Features of 18-8 Stainless Steel Socket Head Cap Screws
Superior Corrosion Resistance
The chromium content in 18-8 stainless steel forms a passive protective layer that helps resist corrosion, staining, and oxidation. This makes these fasteners suitable for marine equipment, food processing machinery, water treatment systems, and outdoor structural components.
High-Strength Internal Hex Drive
The socket head design features a precision-formed internal hex drive, allowing for higher torque application compared to traditional hex head bolts. This makes installation easier in confined spaces while providing a clean, low-profile appearance.
Precision Machining & Thread Accuracy
Available in a wide range of fractional diameters such as 1/4", 5/16", 3/8", 1/2", and larger, these screws are manufactured with unified coarse (UNC) and fine (UNF) thread options to meet exact project requirements.
Common Applications
Fractional 18-8 stainless steel socket head cap screws are widely used in:
-
