At Ananka Fasteners Pvt Ltd, we manufacture fasteners to the dimensional requirements of DIN 988. Shim rings and supporting (spacer) rings. Precision flat washers used to take up axial clearance and set spacing on shafts and in assemblies. Supplied in many bore x outside-diameter combinations, each available across a range of controlled thicknesses; the table below is a representative selection of common bore/OD pairs and the standard thickness ladder.
