Length: 1D
Material: Stainless Steel 304

M5 x 1D Helicoil Inserts are precision-engineered wire thread inserts designed to provide durable, wear-resistant internal threads in materials such as aluminum, magnesium, plastics, and other soft metals. These inserts restore damaged threads or reinforce new threads in tapped holes, offering high load-bearing strength, vibration resistance, and corrosion protection.

In the term M5 x 1D, the 1D refers to the installedlength of the Helicoil insert,during installation.

• “D” is the nominal thread diameter. For M5, D = 5 mm.
• So, 1D = 1 5 mm = 5 mm in length
• This length refers to the axial height of the coil once installed in the tapped hole

Made from high-quality stainless steel 304, Helicoil inserts ensuretight tolerances, smooth thread engagement, and longevity even in demanding industrial environments.

Use Cases:

• Automotive & Aerospace: Repair stripped threads in engine blocks, aluminum housings, or castings
• Electronics & Instrumentation: Reliable thread reinforcement in plastic or alloy enclosures
• Mechanical Assembly: Prevents thread stripping in soft metals during torque application
• Maintenance & Repair Operations (MRO): Ideal for fixing damaged or worn threads

Installation Tip:

1. Drill the hole using the specified Helicoil drill bit size
2. Tap the hole using the Helicoil STI (Screw Thread Insert) tap
3. Use the Helicoil installation tool to wind the insert into the tapped hole
4. Break off the tang (for through holes, if required)
