RING LOCKING INSERTS

Inserts are used in structural assemblies, such as forgings, castings and machined components where repeated bolt assembly and removal could jeopardize the integrity of tapped threads in a less durable parent material. These inserts act as a hardened thread “liner” to prevent wear and protect expensive housings, cases, or gearboxes from thread damage. Inserts are also often used to repair damaged threads in housings, and deliver performance and durability superior to original stock designs.

thread rolling

Thread rolling is a type of cold forging that is compatible with any ductile metal. It is the preferred method for producing strong, uniform external threads. For highest quality results, thread rolling is performed on centerless ground blanks.
