Among all the self tapping threaded inserts, 302 series is the most widely used one. The slots have the function of cutting and a slightly locking force towards inner. 302H is same as 302 series while add a flange on the head, which greatly enhance the pull-out force and torsion.
◆ Provide high strength internal threaded in the soft material for times of maintenance or dismounting.
◆ Can repair the broken internal threaded in the base material effectively.
◆ Can be used after casting, thermosetting or other technological procession, which can simplify the structure of products and increase the production.
◆ Can burden high load, so smaller inserts can be used to make the product structure design more compact.
Such kind of insert can be used on material with low hardness and tensile strength, such as light alloys (Aluminum, Magnesium, Zinc and the alloys), cast irons, bronze/brass, thermosetting plastic, laminated board and wood. The Inserts can easily tap into the soft base materials to provide a high strength internal thread or to repair the broken thread.
