What is a Threaded Insert Sizing Guide?

A Threaded Insert Sizing Guide is a comprehensive resource that helps users select the correct size and type of threaded insert for their specific application. Threaded inserts are used to create strong, durable threads in materials that may not be able to support them otherwise, such as wood, plastic, or soft metals. The sizing guide typically includes information on the outer diameter, inner diameter, length, and thread pitch of the inserts, ensuring that users can make an informed decision.

Key Components of a Sizing Guide

• Outer Diameter: The external size of the insert, which must match the hole drilled into the material.
• Inner Diameter: The internal thread size, which must match the screw or bolt being used.
• Length: The overall length of the insert, which affects the depth of the thread.
• Thread Pitch: The distance between threads, which must be compatible with the screw or bolt.

Why is a Threaded Insert Sizing Guide Important?

Using the correct size of threaded insert is crucial for ensuring a secure and long-lasting connection. An improperly sized insert can lead to stripped threads, weak connections, or even material damage. A sizing guide helps users avoid these issues by providing detailed specifications and recommendations based on the material and application. This is especially important in industries where precision and reliability are paramount, such as aerospace, automotive, and construction.

Benefits of Using a Sizing Guide
