Socket shoulder screws, often referred to as stripper bolts, are essential components in mechanical assemblies where a precise pivot point or sliding motion is required. Unlike standard bolts, these fasteners feature an unthreaded shoulder that is larger in diameter than the threads, providing a smooth surface for bearings or pulleys to rotate around. This makes them a go-to choice for tool and die makers, as well as engineers working on precision machinery.
Our range follows the ISO 7379 standard, ensuring tight tolerances and consistent performance across various sizes, from M5 and M6 through to larger M8 options. Whether you are looking for self-colour steel for high-strength applications or zinc-plated options for enhanced corrosion resistance, we stock the specific dimensions needed to keep your project moving. The internal hex drive allows for high torque application without the risk of cam-out, which is vital when working in confined spaces or on heavy-duty equipment.
Choosing the right shoulder screw is about more than just thread size; it’s about the diameter and length of the shoulder itself. At Duchy Fasteners, we understand that precision is non-negotiable. That is why we provide trade-quality fasteners with the convenience of fast UK-wide shipping. From small maintenance tasks to large-scale manufacturing runs, our selection offers the reliability you need at competitive prices.
