Warranty

Ko-ken USA, LLC (“Koken”) prides itself on Ko-ken Tools’ life in the field and customer satisfaction. Koken warrants that each product sold shall be free from defects in material and workmanship under normal application, use and service for the life of the product. Ko-ken USA is not under obligation to warranty any tools that are still capable of performing the job for which they were intended. In order to validate a warranty, the requester has to be the initial purchasing customer of the tool. Warranty acceptance/review does not validate if a tool was abused or not. Ko-ken’s sole obligation under this warranty, at Ko-ken’s sole discretion, is to repair or replace, free of charge, any part or parts found to be applicable for warranty, provided that the product (i) is delivered, postage prepaid, to Ko-ken USA, LLC, 10 Kidder Road, Chelmsford, MA 01824; (ii) has not been subject to ABNORMAL USE in any manner. Ko-ken USA is not liable for incidental, special or consequential losses, costs or damages incurred by buyers or others arising from the sale, warranty, handling or use of the product.

Ko-ken tools are known to last longer in high volume manufacturing in comparison to competitors, however, their lifetime is still limited in such environments. Therefore, Ko-ken USA does not warrant tools for high volume manufacturing usage. 

 THIS WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED, WRITTEN OR ORAL, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY AND OF FITNESS FOR A PARTICULAR PURPOSE. IN NO EVENT SHALL KOKEN BE LIABLE FOR ANY INCIDENTAL, CONSEQUENTIAL, SPECIAL OR OTHER DAMAGES IN EXCESS OF THE REPLACEMENT COST OF THE DEFECTIVE PART(S).

Ko-ken USA will only honor warranties for products purchased directly from authorized distributors designated by Ko-ken USA by/for customers who were residing in North America at the time of purchase.

Note that if you purchased your Ko-ken product oversees or by an unauthorized distributor then you have to reach out to the original vendor for warranty. Ko-ken USA is only liable for its distribution of Ko-ken Tools within North America.

  • Do not drop Koken tools from high places.

  • Never substitute a HAND Socket for a INDUSTRIAL or IMPACT Socket and vice versa.
