Stainless Bolt Industry's SS 316LN Cap Screw is an impermeable to fastener. Precision-engineered SS 316LN Cap Screws are available from Stainless Bolt Industry, a leading manufacturer and supplier of high-performance stainless steel fasteners made to withstand the harshest industrial conditions. These screws are made of low-carbon, nitrogen-strengthened austenitic stainless steel, which offers remarkable mechanical strength and resistance to stress corrosion cracking, pitting, and crevice corrosion. SS 316LN cap screws are widely used in the offshore, shipping chemical processing, pharmaceutical, and nuclear power industries. They are perfect for applications that involve exposure to chlorides, high pressures, or extreme temperatures. The Stainless Bolt Industry guarantees that every fastener provides exceptional performance, lifespan, and safety in crucial operations by adhering to international standards, quality, and dimensional precision.
The precision-machined, hex-socket SS 316LN Cap Screw is made from AISI 316LN stainless steel, a low-carbon, nitrogen-enhanced variant of 316 stainless steel. This screw is incredibly resistant to intergranular corrosion because of its low carbon content, which lessens the chance of carbide precipitation during welding, and its extra nitrogen, which increases tensile strength. This cap screw is ideal for use in pressure vessels, chemical processes, and structural components due to its exceptional resistance to pitting and crevice corrosion, long service life, and extraordinary strength retention in challenging conditions.
