The J.Lanfranco 1-3/8”- 6 THU Self Locking Nut is a heavy-duty, full-height hex nut possessing self-locking technology. These lock nuts are made from grade 8 alloy steel and built for extreme performance in critical railroad applications such as railroad diamonds and turnouts. They are proven resistant to loosening regardless of the amount of vibration, shock or impact the THU endures.

The THU is a single-piece design requiring no inserts for installation. Locking torque applies evenly into a single plane on opposite sides of the nut creating a superior hold. The locking slots expand and grip onto the flanks of the bolt, keeping it locked tightly into position, even when subjected to very heavy train loads and high traffic. And, because the dual-locking slots function independently of bolt tension, they can be removed and reused as well.

Thanks to the THU’s self-locking technology, these nuts from Industry-Railway Suppliers help greatly reduce labor time and cost because they do not require frequent tightening or maintenance, unlike the traditional nut-and-lock-washer method. These anti-galling locknuts also require no grease or anti-seize paste yet remain resistant to corrosion even at extreme temperatures. This reduces waste and maximizes operational efficiency to your railroad infrastructure.

The THU’s standard nut size is compatible with any railroad joint bar where a locknut would be used. They are highly-durable and long-lasting making the most efficient railroad locknut choice for you and your team. Shop IRS’ railroad switch keys and locks for sale for any additional needs.
