HC - HELI COIL

• Stronger Assemblies: Tapped threads are strengthened because the inherent flexibility of the insert provides a more balanced distribution of dynamic and static loads throughout the length of thread engagement. This flexibility also compensates for variation in lead and angle error allowing each coil to carry its share of the load.
• No Thread Wear: Thread life is dramatically increased even after repeated assembly and disassembly, because the insert hardness and surface finish practically eliminate erosion of the thread form due to friction.
• Corrosion Resistance: Under normal environmental conditions, Heli-Coil inserts minimize galvanic action within the threaded assembly because of their superior corrosion resistance.
• Design Flexibility: Bolt tensile strength can be balanced against parent material shear strength, assuring bolt failure rather than parent material damage. Five insertlengths are available in each thread size.
• Elliminate Stress: Virtually no stress is introduced into the parent material because there is no staking, locking, swaging or keying in place — the outward spring-like action of the insert holds it in place.
• Minimize Space & Weight Heli-Coil inserts allow use of smaller bosses, flanges and fasteners than any other insert. Heli-Coil inserts can generally be incorporated in existing designs, where no provision has been made for an insert, without increasing boss size.
• Minimize Total Cost: Cost savings abound. Lower insert cost, lower installation cost, and Heli-Coil inserts provide design flexibility byallowing a wide choice of parent materials while maintaining maximum threaded assembly strength.
• True Clamping Torque: Maximum clamping action and bolt tension are assured withminimum wrench torque, because of the mirror-smooth surface finish of Heli-Coil inserts.
• Wide Temperature Range: Heli-Coil stainless steel inserts can be used in temperaturesranging from –320°F to +800°F.
• Quality & Reliability: Stringent Quality Assurance and Engineering Standards are rigidly enforced in all phases of the manufacturing process. This assures integrity of your product design.
