Push-On Inserts are self-locking, spring steel shaft retainers that provide a larger bearing surface so parts can be installed with automated assembly or pre-assembled to trim pieces. These Push-ons are available in 3-, 4-, 6-, 7- and 8-prong designs to fit non-threaded diameter studs in a wide variety of sizes. These self-threading fasteners greatly reduce installation costs and problems associated with cross threading. Their prevailing torque provides excellent resistance to vibration, and can simplify your designs.
