Stripped or damaged a metric bolt thread? This Irwin hex die is your fix-it tool. It's a single, high-quality carbon steel die for cutting or repairing M14 x 1.5 threads. That's a 14mm diameter with a 1.5mm pitch – a pretty common size for automotive, machinery, and other industrial stuff. The hex shape (six-sided) lets you turn it with a standard wrench or socket, which is way easier than using a round die with a diestock. Part number is 6950ZR. It's brand new in its packaging, made right here in the USA by Irwin, a trusted tool brand. This isn't for cutting brand new threads from scratch on a rod (though you could in a pinch), it's perfect for cleaning up rusty threads or fixing minor damage on a bolt or stud. Just screw it on, follow the existing threads, and it'll recut them to like-new condition. Saves you from having to replace expensive bolts. A must-have for any serious mechanic or machinist's toolbox. No warranty listed, but Irwin tools are solid. The UPC is 042526069505. Keep your threads in good shape and avoid getting stuck with a bolt you can't use. Grab this die and be prepared.
