Self-Tapping Inserts
Self-Tapping Thread Inserts
Self-tapping inserts create high-strength internal threads by tapping their own mating thread directly into the base material, eliminating the need for pre-tapped holes. They are widely used to reinforce threads in aluminium, magnesium, plastics, wood, and composite materials.
Why Use Self-Tapping threaded Inserts?
- Increases thread strength in low-density materials
- Permanent, wear-resistant, vibration-resistant joints
- Enables repeated assembly/disassembly without thread failure
- Repairs damaged or stripped threads with no welding
- Improves load distribution and pull-out resistance
Types of Self-Tapping threaded Inserts
Cutting Slot Type (Slot-Cut Inserts)
Self-tapping inserts with longitudinal cutting slots that form the internal thread as they are driven into the pre-drilled hole. Suitable for easy-to-medium machinable materials such as aluminum, zinc die-cast, and plastics. Provide good pull-out strength and are widely used for thread reinforcement and repair.
Cutting Hole Type (Hole-Cut Inserts)
Self-tapping inserts with multiple radial cutting holes instead of slots that control chip formation and optimize cutting forces. Designed for harder materials or applications where controlled chip evacuation is important. Often used in alloy castings, automotive housings, and spark plug seat repairs.
Applications of Self-Tapping Inserts
Aluminum, Magnesium & Zinc Die-Cast Housings
Self-tapping inserts reinforce threads in soft light metal castings, preventing thread stripping during assembly and service. Suitable for high torque tightening and repeated screw cycles.
Plastics and Moulded Components
Provide durable metal threads in thermoplastics and composites where direct tapping cannot withstand load or wear. Ideal for enclosures, fixtures, and structural plastic parts.
Engine & Powertrain Housings
Reinforce threaded joints in aluminum EV housings exposed to torque loads, sealing, and thermal expansion without risk of thread pull-out or galling.
Machine Tools & Automation Equipment
Create wear-resistant threads in fixtures, jigs and mechanical assemblies where precision alignment, torque control and repeated adjustments are common.
Thread Repair in Automotive & Industrial Service
Restore damaged or worn threads in the field, workshop or machine shop, especially in spark plug seats, oil pan threads, valve covers and cast housings.
Marine Applications
Offers corrosion resistance in components for vessels and offshore platforms, maintaining strength in harsh environments.
Machinery
Used in industrial machinery for strong, stable connections in gearboxes, motors, and structural supports.
Solar Energy Systems
Secures solar panel frames and mounting brackets, ensuring reliable performance in renewable energy setups.
Wind Turbines
Fastens turbine components, withstanding high winds and vibrations in renewable energy applications.
Medical Equipment
Ensures safety and durability in hospital beds, surgical instruments, and diagnostic tools.
Toys and Gadgets
Provides secure fastening in plastic toys and electronic gadgets, ensuring durability during frequent use.
Sports Gear
Ensures safety and reliability in helmets, protective pads, and sports equipment requiring durable threaded connections.
Material Options
Self-tapping inserts are typically produced in:
Case Hardened Steel (Zinc Plated)
Stainless Steel 303 grade
Brass
