Self Locking, Case Hardened Threaded inserts provide high-quality, permanent, wear-resistant internal threads and are designed to be installed in molded or drilled holes in one simple step. They are cylindrical, metal bushings with features on the outside that anchor them into a plastic or metal base material, and provide a fast and inexpensive way to solve all your stripped thread needs.
Inserts come in two different wall thicknesses – standard and thin wall. Use the standard insert where space is not an issue. Installation of the standard insert allows more flexibility with critical tolerances. Use the thin-walled insert where space is limited, and the insert may be near the edge of the housing. Small motors, transmission cases and landscaping equipment are examples.
With Rockmount Threaded Inserts, stripped-thread problems can be corrected in minutes with no special tools or procedures. Save time, money and aggravation by simply drilling a new hole and screwing in the self-tapping, case hardened insert.
