Reinforce and repair internal threads with this versatile stainless steel threaded insert set. Designed for use in softer materials such as plastic and copper, these self-tapping inserts help create strong, stable threaded holes for dependable fastening.
The precision-formed 302 stainless steel construction distributes load evenly while supporting long-term connection integrity. The self-tapping design helps restore damaged threads and reduces the risk of further thread wear or peeling.
With multiple metric sizes organized in a convenient storage box, this set is a practical addition to a workshop, repair bench, furniture project, or DIY tool collection.
Suitable for mechanical repairs, furniture applications, professional workshops, and DIY projects involving compatible plastic or copper materials. Install using an appropriate wrench and suitable preparation for the selected insert size.
