M12 x 1.75 Tang-Free Helicoil Inserts for metal are crafted from high-quality stainless steel, featuring a rhombus-shaped cross-section and a mechanically curled spring design. These inserts are embedded into the internal threads of various materials, providing high connection strength, shock resistance, impact resistance, wear resistance, and the ability to withstand high temperature variations. They also facilitate metric and inch thread conversion, enhancing overall thread stress distribution. When original threads are stripped, Tang-Free Helicoil Inserts effectively repair and restore them. Their key characteristics include higher precision, increased durability, restoration of original size, and convenient, quick maintenance.
