Threaded Inserts / Heli Coil:M18 x 1.5 x 18 - DIN 8140 B

This product is a fine-threaded metal insert, specifically a Heli Coil, engineered to reinforce threaded holes in various materials. It features an M18 nominal diameter and a 1.5 millimeter pitch, conforming to the DIN 8140 B standard. These inserts are commonly selected by engineers and manufacturers to restore worn threads or install threads in soft materials like aluminum or plastics where direct tapping is insufficient. The 18 millimeter nominal length provides a secure engagement depth for medium-sized fastening applications within this diameter class. Buyers should verify the thread pitch and length match their existing hole geometry to ensure proper fit and torque resistance.
