Description

Thread Repair Set M18×1.5 – Complete Helicoil Insert Kit

Brief Overview

This M18×1.5 thread repair set delivers a complete solution for restoring damaged or stripped threads in industrial and automotive applications. The kit arrives as a ready-to-use system in a durable plastic case, eliminating the need to source individual components. Whether you're servicing engine blocks, gearboxes, or structural assemblies, this system restores threads to full structural integrity without requiring replacement of the parent component. Complement your inventory with smaller-diameter thread repair options or step up to larger-gauge repair sets to cover your full range of service demands.

Key Components & Features

  • 10 Stainless-Steel Helicoil Inserts: Wire-coil construction provides reliable thread locking and corrosion resistance. M18×1.5 pitch ensures compatibility with standard fasteners across automotive and industrial equipment.
  • Precision Twist Drill Bit: Machined flutes optimized for clean hole preparation at the correct diameter for insert installation.
  • Thread Cutting Tap: Straight-flute design cuts clean threads in the prepared hole to accept the helicoil insert. Sharp cutting edges ensure burr-free performance.
  • Dual T-Handle Installation Tools: Two blue-handled drivers with black metal shanks allow controlled insertion and seating of helicoil coils. Ergonomic design reduces operator fatigue during installation.
  • Tang Breaker (Hex Key): Specialized tool for cleanly removing the tang after insert installation, ensuring a flush, professional finish.
  • Compact Molded Storage Case: Clear plastic case with blue latches organizes all components in individual compartments. Professional presentation suitable for shop inventory or customer delivery.

Why Resellers Choose This Kit

Profit Leverage: Thread repair kits command strong margins compared to replacement parts. A single damaged M18 hole that would require component replacement (potentially $500–$2,000) can be restored for under $50, creating immediate customer value and repeat business.

Complete Solution = Higher Close Rate: Offering a ready-to-use kit rather than loose components eliminates customer objections about missing tools or incorrect specifications. Professional presentation in a molded case justifies premium pricing.

Stock Efficiency: One compact unit replaces inventory slots for five or six individual tools. Fast inventory turnover due to consistent demand across automotive repair, industrial maintenance, and equipment rebuilding sectors.

Customer Loyalty: Thread repair capability positions your shop as a full-service repair facility, not just a parts supplier. Customers who trust you with repairs return for parts and additional services.
