HEAT INSERTS PACK of 10/25/50 VORON STYLE (M3x4mm)

Sonic inserts also known as Heat set inserts are small, threaded brass cylinders designed to create strong, permanent threads in plastic. They're ideal for situations where traditional screws or nuts wouldn't hold up, such as in 3D-printed parts.
(3x5x4)

Specifications:

• Thread: M3
• Height: 4mm
• Diameter on barbs: 5mm
  
• Bottom ring Diameter: 4.2mm
  
• Hole size needed: 4.25mm - 4.5mm

Here's how they work:

1. Heat the insert: Use a soldering iron to melt the insert's exterior.
2. Insert and press: Quickly press the heated insert into the hole. As it cools, the melted plastic hardens around the insert's barbs and threads, creating a secure grip.
   

Benefits of Sonic Inserts:

• Stronger than tapped threads: Sonic inserts provide superior pull-out resistance compared to simply tapping threads directly into the plastic.

• No pre-threading needed: Unlike other threaded inserts, sonics don't require pre-threading the plastic, saving you time and effort.

• Heat-activated installation: The heat-activated process is quick and easy, requiring no special tools or adhesives other than a soldering iron.

• Reusable: Sonic inserts can be removed and re-inserted multiple times without losing their grip.
  
  

Overall, Sonic Inserts are a versatile and effective solution for creating strong, permanent threads in plastic. They're easy to use, require minimal prep, and offer excellent holding power for a wide range of applications.
