Thread Repair Inserts M5 x 0.8mm Helicoil Type Stainless Steel 25pc

A pack of 25 M5 x 0.8mm helicoil inserts for repairing damaged or worn internal threads. Made from stainless steel, these thread repair inserts are used to restore a secure fixing point where an original thread has stripped, pulled out or become weak through repeated use.

Used across garage work, workshop repairs and general maintenance, they are suitable for restoring M5 threads in metal components, machinery parts, tools, fittings and other threaded holes. They are also useful when reinforcing threads in softer materials such as aluminium, plastic or wood, helping provide a stronger hold for bolts, screws and other M5 fasteners. For regular servicing and repair work, keeping the correct insert size to hand can save replacing the full part.

The inserts are sized for M5 threads with a 0.8mm pitch, so they need to be matched correctly to the fastener and the proper helicoil tap and installation tool, which are sold separately. Stainless steel construction helps with wear resistance and corrosion resistance in everyday workshop conditions, while the 25-piece quantity gives you enough inserts for multiple repairs or repeat jobs. They are best fitted into a clean, properly prepared hole to achieve a reliable helicoil repair, and the pack is practical to keep in the toolbox or workshop drawer for common maintenance work.
