Helicoil Plus Thread Repair Kit - 1 / 4-28 - 1 / 2-20, UNF

The Helicoil Plus Thread Repair Kit, with part numbers 1 / 4-28 and 1 / 2-20, is specifically designed for professional users.

• It features the innovative Plus inserts that enable you to establish a new thread quickly and effortlessly in just a few simple steps.
• These durable and robust inserts offer long-lasting performance and can save you money by preventing the need to replace more expensive components.

Each kit comes equipped with all the essential tools and includes three different lengths of HELICOIL Plus inserts, as well as comprehensive step-by-step instructions for use.

The wire within these inserts boasts a rhombic profile that has been carefully fashioned into elastic spirals; the initial thread is purposely made smaller to facilitate straightforward installation.

• To fit the insert, simply place it and screw it in using an appropriately sized mandrel - much like how you would use a tap.
• The thread insert, characterised by its precision-machined rhombic profile, can turn within the component freely, ensuring that the resulting internal thread remains true to gauge and can accommodate the secure insertion of a screw at both ends.
