When you are designing a mechanical assembly or executing an urgent factory maintenance repair, precision is everything. Traditionally, if you need to secure a component tightly onto a rotating or moving shaft, you have two engineering options: machine a precise groove into the metal to seat a standard circlip, or thread the shaft to take a bolt or locknut.
But what if you don’t have the time, the machinery, or the material thickness to cut a groove?
That is exactly where the M1440 Series Metric Grip Ring steps in. Known across the engineering sector as a premier “push-on fix,” this self-locking fastener provides high-thrust retaining power on entirely plain, ungrooved shafts.
Standard external circlips (like the DIN 471) rely entirely on the shoulder of a machined groove to hold axial loads. The M1440 Metric Grip Ring, however, relies on brute frictional force and advanced radial geometry.
