It is the most used steel in the world. The countersunk screw head is designed in a way to be sunk into the panel when driven into it. There are SS 316 Allen Key Countersunk Screw types which are made up of a more corrosion resistant material. The csk screws can also be self tapping screws. There are different types and sizes such as the M6 CSK Allen Cap Screw made for different applications. The allen cap can be tightened and loosened with allen keys. These are useful to install the screws into limited and narrow space. The CSK Allen Head Screw is used in wooden, metallic, marine, general corrosive and many other domestic application types. As a leading supplier and stokiest of the different allencsk screws. Please contact us for more information on the CSKAllen Bolt and the pricing.

SS 304 Nut Bolt, 304 Stainless Steel Hex Nuts Suppliers in India, Check Updated 1.4301 Bolt Price list

The SS 304 Nut Bolt can have up to 515MPa minimum tensile strength and 40% elongation with 201HB max hardness. The high mechanical properties come through the chemical composition with carbon, manganese, silicon, phosphorus, sulfur, chromium, nickel and nitrogen. The 304 Stainless Steel Dowel Pins are another type of the fasteners. The fasteners can come as threaded rods, screws, bolts, nuts and washers. The bolts range from 3mm to 200mm. The length of the 1.4301 304 Stainless Steel Threaded Rod ranges from M02 to M33 in the metric system. The specifications vary according to the IS, BS and ASTM standards. As a leading manufacturer, we also produce and supply different types of SS 304 Screw in different sizes as well. Please feel free to contact us for more information and pricing of the different fasteners such as the UNS S30400 SS 304 Stud Bolts and the prices.

The different composition, production methods and other mechanical and physical properties all matter. The SS 304 hex bolt is the most used in terms of the material grade as the 304 is a basic austenitic stainless steel with chromium and nickel composition. The torque strength is also good. The next most used is the ss 316 hex bolt due to the added corrosion resistance as it has molybdenum added to the content. The length of the bolts can range from 1 inch to 24 inches depending on the standard and application type. Some applications demand Stainless Steel heavy hex bolt due to the heavy load bearing nature. The bold diameter can range from ½ inches to 2 ½ inches depending on the standards such as the hex bolts din 933. The different standards are useful to maintain a universal measurement and identification of the bolts as they are used in different applications. The thread types, lengths, widths, head and other properties of the bolts vary with different standards such as the hex bolts din 931. The bolts are also specified for different applications such as fittings and flanges. There are differences to suit the connection types such as the hex flange bolts and hex fittings bolts. The fasteners also come with different standards for different use cases. To have an international measure, there are ISO numbers to indicate the types such as the hex bolt iso 4014. Please feel free to contact us for more information and pricing of the hex bolts and other types of fasteners.
