ASTM A193 B8M Round and Hex Head Machine Bolts manufacturer and exporter in India

Machine Screw is one of the most widely used products among dozens of standard fastener. It can be either coarse-threaded or fine-threaded, and are usually available with a wide range of head types. The most common applications that machine screws aim to be used for involve metal parts and panels needing to be fixed securely together. Stainless Steel Machine Screw has a uniform diameter the entire length of the shaft as opposed to tapered screws which have a pointed tip. It is used to fasten machine components, appliances, etc. Machine Head Screw are of different types such as slotted or flat head machine screw, Philips head machine screws, torx head and hex head machine screws, pan head machine screw, fillister or cheese head machine screws. Round Head Machine Screw is similar to 'flat' heads, but with no driving recess. It is used for shorter screw lengths to provide a longer thread grip and shallower countersinking. Hex Head Machine Screw allow for more torque to be applied to the screw with a socket wrench. It is most often used with a nut as a means of tightening unless they have a pre-threaded hole with the exact thread pitch. It is most commonly offered in smaller sizes.
