ISO Metric Thread Inserts

About the product

1.ISO metric thread  are the gold standard for threading, designed to ISO specifications for high precision and reliability.

2.ISO inserts are available in two types: external and internal, to meet different threading needs.

3.ISO threaded inserts are available in right-hand (R) and left-hand (L) directions, ensuring compatibility with a variety of threading directions.

4.Threading inserts are versatile and can handle 60° universal threads and ISO metric threads, making them a must-have in industries such as machinery and automotive.

Specification：

Material Composition

• Base Materials: Available in two primary alloys to suit application needs:

• Stainless Steel (A2/A4): ISO Threaded Inserts The most common choice, offering corrosion resistance (ideal for automotive undercarriage or outdoor machinery) and tensile strength up to 800 MPa.

• High-Strength Alloy Steel: Heat-treated to 12.9-grade hardness, used for heavy-duty applications like industrial machinery or aerospace components requiring maximum load-bearing capacity.

  
  

• Surface Treatments:

• Zinc Plating: Adds rust protection for general-purpose use in dry environments.

• PTFE Coating: Reduces friction during installation and prevents seizing, perfect for high-vibration applications (e.g., engine mounts).

• Passivation: Enhances stainless steel’s corrosion resistance for marine or chemical processing equipment.

Key Features

1. ISO-Certified Precision
   Manufactured to strict ISO Inserts standards (e.g., ISO 13688 for thread repair inserts, ISO 898-1 for mechanical properties), ensuring consistent thread pitch (M1–M64 sizes available), major/minor diameter tolerances (±0.015mm), and 60° thread angle accuracy. This eliminates mismatches with ISO metric fasteners, reducing assembly errors by 90% vs. non-certified inserts.

2. 
   

3. Dual Type & Direction Options

• External Inserts: Cylindrical design with external threads for creating new threads on shafts, studs, or bolts—common in machinery spindle manufacturing.

• Internal Inserts: Helical or solid bushings with internal threads, used to repair stripped threads in soft materials (aluminum, plastic) or reinforce weak threads in high-stress parts (e.g., automotive cylinder heads).

• Thread Directions: Right-hand (R) for standard applications; left-hand (L) for reverse-rotation components (e.g., lathe spindles, motorcycle clutch bolts).

Automotive: Repairing stripped threads in engine blocks, securing suspension components, and reinforcing transmission housing fasteners.

Machinery: Creating durable threads in gearboxes, hydraulic manifolds, and tooling fixtures—where vibration resistance prevents loose fasteners.

Aerospace: Lightweight stainless steel inserts for aircraft interior components (e.g., seat tracks) and high-strength alloy inserts for landing gear brackets.

Electronics: Miniature M1–M3 inserts for securing circuit boards in smartphones, laptops, and industrial sensors.

Thread creation (external inserts on shafts).

Thread repair (internal inserts in stripped holes).

Thread reinforcement (preventing wear in high-cycle applications like door hinges).

Compatible Machines & Installation Tools

Installation Equipment:

Manual Tools: Tap wrenches and insert drivers for low-volume jobs (e.g., repair shops).

Semi-Automatic Tools: Pneumatic insert installers (e.g., RS PRO 18V cordless models) for medium-volume production.

CNC Machines: Integrated into CNC milling/turning centers (Fanuc, Haas) with specialized toolholders for high-volume, automated insertion (e.g., automotive part production lines).

Machining Compatibility: Works with standard tapping tools (HSS or carbide taps) for pre-threading holes, ensuring easy integration into existing workflows.

User Testimonial

Carlos Mendez, production supervisor at AutoParts Global, shares: “We switched to ISO metric inserts two years ago, and our thread-related defects dropped from 12% to 1%. The stainless steel inserts hold up perfectly in engine blocks—even with coolant exposure— and the left-hand options were a lifesaver for our reverse-rotation transmission parts. Installation is so straightforward, even our new technicians master it in a day. They’ve cut our rework time by 50 hours a month easily.”

Summary

ISO metric thread inserts combine ISO-certified precision, versatile design, and durable materials to solve threading challenges across industries. Their ability to create, repair, and reinforce threads—while compatibility with global standards—makes them a cost-effective, reliable solution for manufacturers prioritizing consistency and long-term performance.
