Replenish a thread repair kit or stock a dedicated size with Alpha 304 Stainless Steel UNC Wire Thread Inserts | 9/16″ x 12 TPI x 1.5D (5 Pack). Designed for 9/16″ x 12 TPI repairs, these diamond-section 304 stainless steel inserts create a durable internal thread when fitted into the matching oversized STI thread. Their profile expands during installation to resist pull-out and spread fastener load over a wider area of the parent material. The 1.5D length gives a defined engagement depth for this product, while the 5-piece quantity suits repeat repairs. Pair the inserts with the correct STI tap, installation tool and tang removal method. The hangable tube keeps the pack contained and easy to store.
