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.
Adapters are available in these head styles: Allen Hex Type sizes; Metric Hex Type sizes; Phillips Head; Slotted Head, Bristol 6-flute Multispline; Reed and Prince; Square Head; TORX and Gunsmith Specialty Slotted. In addition, the 1/4" Square adapter is used to drive your standard sockets.
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 0F to retain their hardness.
