Free Running Helical Inserts

Free running inserts are designed to make threads or repair worn threads inside tapped holes. They are ideal for providing reliable threading in metals, composites, wood & similar materials. These inserts are usually larger in diameter than tapped holes and are compressed while being inserted, thereby providing maximum surface contact area. Raptor Supplies offers a wide range of free running inserts in Metric, UNC and UNF thread types from Chrislynn and Heli-Coil.

Features

Free running inserts maintain a tight seal, making them suitable for gear housing, drills, printing presses and machinery that produces continuous vibration.
They are produced in standard sizes for Metric, UNC & UNF thread forms.
Chrislynn free running inserts include non-locking helical inserts that can be used to repair tapped holes.
They are available in lengths ranging from 1.688 to 4.5 inches.
Thread reinforcement with helical inserts prevents threaded hole wear (even after repeated use), increasing integrity and extending lifespan.
These flexible inserts are designed such that each coil in the helical insert can adjust to the fastener threads independently. Since the load is evenly distributed, there is more surface contact between the coil and the parent materials, resulting in a strong & reliable seal.
These coil inserts reduce stress and fatigue while maximising thread strength.
