This 4mm diameter precision ground steel length is perfect for fine precision work, small shafts, delicate tooling and detailed model engineering projects. The 4mm size offers increased strength over the smallest diameters whilst remaining ideal for intricate assemblies and precision fabrication work. Ground to an exceptional ±0.0127mm tolerance (well below the 25mm threshold), this steel rod delivers remarkable accuracy for such a fine diameter.
The 333mm length provides substantial material for multiple small-scale projects whilst maintaining easy handling characteristics. High carbon content ensures excellent machinability and reliable response to heat treatment processes, allowing you to achieve the hardness required for miniature cutting tools and precision components. With closely controlled chemical analysis throughout, you benefit from uniform properties and predictable machining behavior.
The chamfered and deburred ends enhance safety when handling these fine diameters, eliminating sharp edges that could cause injury during workshop operations.
