Stainless Steel Self Locking Nuts, Feature : Longer Functional Life, High Functional Efficiency, Reasonable Rates

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.
