HELI INSERT FASTENERS Screw Thread Inserts are manufactured with the strictest quality standards with inspection carried out at all stages of the production process.

• Applied torque does not have to overcome thread friction due to imperfect thread form. Almost all torque is used to stretch the bolt.
• Greater loading for applied torque than ordinary nuts.
• Maintain preload stretch in bolt beyond amplitude of unload vibrations.
• Insert is flexible and compensates for lead and angle errors always presents in making threads.
• Load is more evenly distributed over all engaged threads.
• Can be repeatedly assembled and dis-assembled without loss of efficiency.
