Introduction
A mid-sized tool manufacturer located in Ludhiana recently lost out on a government contract for lakhs because their Single ended Open-jaw Adjustable Wrenches were not BIS-approved. The buyer required wrenches according to IS 6149:1984, and insisted they be ISI-marked.
Missing this certification not only caused financial loss but also affected the manufacturer’s market reputation. This is sadly a common event in India’s hand tool industry—many manufacturers fail to recognize the value in obtaining a complete set of BIS specifications, resulting in financial penalties, unsupported bids in tenders, and reject bids due to a lack of faith from end-users.
The BIS list of Single-ended Open-jaw Adjustable Wrenches provides reassurance to your customers that your product will comply with long-term safety standards, as well as providing access to domestic and international markets.
What is IS 6149:1984(single ended open jaw wrenches)?
