316L Bolts specifications mandate the standards and requirements of bolts and nuts in the 316 grade material. Rolex Metal Distributors is a manufacturer & exporter of all kinds of 316L Stainless Steel Bolts and in other material grades as well. We manufacture the S31600 Bolt which are the second most used of stainless steel grades next to the 304 material. Our Stainless Steel 316L Fasteners are of superior quality and are used in various industries such as food processing plants and components, marine and sea water applications, petrochemical industries and in aerospace industry as well. These SS 316L Hex Bolts are a chromium nickel alloy with molybdenum in it. The addition of molybdenum makes the 316L Stainless Steel Stud Bolts Yield Strength to be higher with better anticorrosive properties. There is a lower carbon version of the same material as well. The SS 316L Nuts and Bolts are made up of the lower carbon version of the material and they are less corrosive and highly weldable. The 1.4404 Nut Bolt are the specification for 316 and 316L grade bolts, nuts and other fasteners. Our 316L SS Threaded Rod & Studs are stronger and durable. The ASTM A193 316L Fasteners are slightly costlier than the SS 304 bolts but they are of high yield and tensile strength with added anticorrosive properties and high weldability. Therefore our UNS S31603 Screws and nuts are preferred in high cost applications. You can get a full list of products and pricing upon contacting us.

316L screws are made up of 316L material but of a lower carbon version. The 316L material is a nickel chromium alloy with added molybdenum in it. This combination makes the already corrosion resistant material more corrosion resistant. We manufacture different types of fasteners in this material for use especially in chloride rich environments. The 316L Stainless Steel Deck Screws are sharper and longer and are specifically designed to fit with wooden or other non-metallic boards. There are other types such as the 316L Stainless Steel grub screws which lack the head so that they could be fully incorporated into the fastening surface.
We also produce the Stainless Steel 316L countersunk screws which are used to make sure that the screw is screwed down as deep as possible so that the surface could be covered with other material without being blocked by the screw. Due to the lower carbon content, the corrosion is very low but the strength is also compromised to a certain level in the 316L fasteners. On the other hand, these are useful in applications that require high corrosion resistance and permanent use such as the 316L Stainless Steel Set screws. These screws are used in a manner that they are used to penetrate cement structures and concrete without the aid of any anchoring devices. We also supply Grade 316L socket head cap screw which are used in interior and exterior applications that require and aesthetic appeal. Contact us for further information.
