Threaded Inserts / Heli Coil:M4 x 6 - DIN 8140 B

Threaded Inserts, commonly known as Heli Coils, are helical spring-like fasteners designed to be embedded in tapped holes to create a durable internal thread. This specific model features an M4 nominal diameter and a nominal length of 6, manufactured to the DIN 8140 B standard. These inserts are primarily used in applications where the parent material is susceptible to wear, stripping, or damage from repeated assembly and disassembly cycles. Buyers select this component to reinforce soft materials, such as aluminum or plastic, ensuring a longer service life for the threaded connection compared to standard machine threads. When choosing the appropriate insert, ensure the nominal diameter matches the required fastener size and the length fits the depth of the prepared hole while conforming to the DIN 8140 B specifications.
