Our stainless steel thread reducer inserts provide a fast, reliable, and cost-effective way to repair damaged or stripped threads, or to reduce the thread size of a pre-drilled hole. Perfect for thread size conversion, these precision-engineered components allow larger threaded holes to accept smaller fasteners, offering maximum flexibility in both design and repair applications.

Designed for strength, durability, and performance, these inserts are made from A2 stainless steel, providing exceptional corrosion and wear resistance. They’re ideal for applications exposed to moisture, chemicals, or harsh environments — including automotive, aerospace, and industrial sectors. Easy to install and long-lasting, our thread reducer inserts also enhance thread strength in softer materials such as aluminium, brass, and hard plastics, ensuring secure fastening and preventing further thread damage over time.

If your application doesn’t require high corrosion resistance and you’re looking for a more budget-friendly option, check out our Mild Steel Thread Reducer Inserts — a practical choice for dry or controlled environments where cost-efficiency is key.

Each insert is precision-engineered and manufactured in the UK, ensuring exceptional quality, consistency, and traceability. By keeping production local, we support sustainable manufacturing, reduce environmental impact through a lower carbon footprint, and help maintain a resilient UK supply chain with shorter lead times and reliable delivery.
