Solid Thread Insert – Permanent Thread Repair and Reinforcement
About the Product
Solid Thread Inserts provide a robust, wear-resistant, and permanent solution for repairing damaged threads or reinforcing new assemblies in soft materials like aluminum and plastics. Unlike coil inserts, these are solid, one-piece bushings that offer superior pull-out strength and resistance to thread stripping. They are ideal for applications demanding the highest levels of structural integrity.
- One-piece, solid metal construction for maximum durability.
- High resistance to vibration, wear, and thermal expansion.
- Superior torque-out and pull-out strength compared to coiled wire inserts.
- Available with keys for positive mechanical lock against rotation.
Used extensively in the automotive, aerospace, and tooling industries, our solid thread inserts ensure structural integrity in high-stress applications. They are installed with standard tools and provide a metric or imperial thread that is often stronger than the parent material, making them indispensable for critical repairs and original equipment manufacturing (OEM).
