GIB HEAD MACHINE KEYS

Our stocked range of gib head keys are available in metric and inch sizes and manufactured from key steel. They are a tapered key with a head at the larger end of the key which serves as a stop mechanism on a rotating shaft. We also have
capabilities to produce keys to order in stainless steel A2 and A4. The head of a gib head key also makes for easier removal during disassembly, plus the key has a 1:100 taper to firmly engage the shaft to the hub. Machine keys are mainly used in areas where frequent removal of the key is necessary, such as agricultural equipment to hold gears and pulleys secure to a rotating shaft.

We also have the capabilities to manufacture Gib Head Keys and other Machine Keys to order in stainless steel A2 and stainless steel A4.  For a competitive quotation for non-standard machine keys, please contact our manufacturing team.
