M3 Insert Manufacturers, Suppliers and Exporters in Canada

An M3 insert is a small, threaded component used to provide durable threads in materials that cannot hold threads well on their own, such as plastics, wood, or soft metals. The “M3” indicates the metric thread size, meaning the insert accommodates an M3 screw with a nominal thread diameter of 3mm.

Types of M3 Inserts:

  1. Heat-Set Inserts:

    • Designed for thermoplastics, these inserts are heated and then pressed into pre-drilled holes. As the insert cools, the surrounding plastic solidifies, securing it in place.
  2. Self-Tapping Inserts:

    • These inserts are designed with cutting threads on the outside, allowing them to cut their way into softer materials like wood or plastics as they are screwed in.
  3. Press-Fit Inserts:

    • Installed by pressing into a pre-drilled hole, relying on friction from the knurled or textured exterior to stay in place.
  4. Ultrasonic Inserts:

    • Installed using ultrasonic energy, which causes the thermoplastic around the insert to melt and form a secure bond.
  5. Threaded Inserts for Metals:

    • These inserts are used to create strong threads in soft metals or thin materials, reinforcing the threaded hole for durability.
