Shoulder Socket

Shoulder Socket

Bolt and Nut Australia carry the largest range of shoulder socket screws (also known as stripper bolts, shoulder bolts) in stock, delivered freight free from our Brisbane warehouse with no minimum spend or order quantity. Shoulder screws are essentially a socket cap screw that is only partially threaded with a shoulder. These bolts are often used on machinery to provide a smooth surface for bearings to ride on. Shoulder bolts are measured by their diameter of shoulder x length of shoulder x thread diameter. Shoulder screws are made from high tensile steel in plain black and the size range is M5 - M16 in a metric coarse thread, Larger diameters and others threads available by request. We also carry socket head cap screws, button head socket screws, countersunk (also known as flat head) socket screws, socket set screws (also known as grub screws), dowel pins, socket shoulder screws and allen keys. A huge database of technical specifications, printable datasheets and product cad drawings are available online for this product.
