Chapman Slotted Head Adapters
Chapman versatile Adapters are constructed of the highest quality Chrome Nickel Molybdenum Alloy Steel and precision made to ensure a proper fit. Their dual purpose knurled Spinner Tops allow for quick finger tightening of threads and for instant "push down" removal of the adapter from the ratchet. Ball-detents plus 'ear' stops quickly position and secure each adapter in the ratchet, the extension, or the screwdriver handle.
Since these adapters are very economical, you may choose to customized the shape of any adapter for a specialized job. Chapman adapters are constructed of fully hardened tool steel, so when grinding these adapters remember they must be kept below 400 °F to retain their hardness.
