Restore stripped 3mm threads in plastic parts with the Core RC M3 Thread Repair Kit (pk10), part number SCH-CR904. Durable brass inserts provide a strong, long-lasting fix wherever M3 screws are used in plastic, making it a practical choice for routine maintenance and repairs.

How It Works

  • Drill out the damaged hole using the included 4mm drill bit.
  • Insert the brass insert into the plastic.
  • As you tighten the M3 screw, the insert expands to grip securely.
  • For an even stronger repair, apply a small drop of super glue, taking care not to contaminate the internal thread.

What’s Included

  • Brass M3 thread inserts (pack of 10)
  • 4mm drill bit

These brass inserts are a strong solution to fix stripped threads anywhere 3mm screws are used in plastic.

Simply drill out the plastic with the included 4mm drill bit and insert the brass insert into the plastic.  As you tighten the screw the insert expands providing a tight grip.

For an even stronger repair apply a drop of super glue being careful not to get any onto the internal thread.
