V-COIL Thread Repair Kit M 40 x 3.0 – 1.5D | Stainless Steel Inserts

V-COIL Thread Repair Kit M 40 x 3.0 – 1.5D

The V-COIL Thread Repair Kit M 40 x 3.0 – 1.5D provides a complete solution for repairing or strengthening damaged internal threads. It restores stripped threads and reinforces low-strength materials, creating highly durable and corrosion-resistant threads — perfect for maintenance, assembly, and small-batch production.

How it works: The STI hand tap cuts a special holding thread, into which a stainless steel wire insert is installed. This results in a stronger, wear-resistant internal thread that often exceeds the original strength.

Application & Advantages

  • Repair of damaged or worn threads
  • Reinforcement of threads in low shear strength materials
  • Recovery of rejected components
  • Creation of new high-strength and durable threads
  • Ideal for maintenance, assembly, and small series production
  • Wire thread inserts DIN 8140, Type S, ISO 2 (6H), stainless steel, free running

Advantages:

  • Flexible usability with extra inserts and drills for sizes up to M12
  • High stock availability for standard and special sizes
  • Designed for hand tapping
  • Higher load capacity after repair due to improved thread properties
  • Temperature and corrosion resistance
  • Functional and durable metal case

Step-by-Step Instructions

  1. Preparation: Drill out the damaged thread to the correct base diameter, deburr, and clean.
  2. STI Tapping: Cut the new thread using the STI hand tap M 40 × 3.0 with cutting oil and steady feed.
  3. Insert Installation: Screw in the V-COIL insert until it sits flush or slightly below the surface.
  4. Tang Removal: Carefully break off the driving tang using the provided tool.
  5. Inspection: Check the thread with a gauge or screw, then clean and finish if needed.
