Repairing of damaged spark plug threads In the automotive industry the HELICOIL® plus thread technology is widely used to provide high strength threads. Thanks to efficient repair of damaged threads, valuable components do not have to be replaced. Thread repair for aluminium engines With HELICOIL® plus thread inserts, cost-intensive replacements of threads in aluminium engines, such as employed in motor sports, are no longer necessary.
HELICOIL® plus Thread Technology ■ Thread inserts ensure heavy-duty connection capability, especially in low-strength materials like aluminium and magnesium. For over fifty years, they have been used in practice and proven reliable. ■ HELICOIL® thread repair is used in metals as well as in many plastic and composite materials. ■ Thread inserts are made from well-proven and tested quality stainless steel (A2) and are formed from rhomboidally profiled wire into a resilient spiral.
Installation of HELICOIL® plus thread inserts HELICOIL® plus holding thread Please only use the special HELICOIL® plus screw tap. For checking the holding thread, we can send you plug limit gauge. Drilling the core hole Please take note of the recommended diameters for drilling the core hole D1 HC from the table on page 36/37. Please note, that information about the twist drill B are only values for orientation. For counterboring (burring) the core hole outer diameter of the couterbore: DHC + 0.
