Wire thread insert referred to as silk, is a new type of internally threaded fasteners, it is a wound made by the diamond-shaped cross-section of wire of high strength, high precision and high surface quality, corrosion, shaped like a spring, the end there is an installation handleusing to install the handle through the use of special tools to be screwed into the screw holes of the substrate-specific, the outer surface of the wire sets rely on elastic fit in the screw holes on its inner surface to form a new screw holes used to screw the screws or bolts,not directly in contact with the substrate to protect the substrate and screws, particularly in the engineering materials of aluminum, magnesium alloy and other low-intensity applications can significantly improve the strength and wear resistance, it also improved the force of the threaded screw or bolt, sothread the overall force, improve the strength of the threaded connection. Also be used to repair worn or damaged threaded.
Application:
1. Assembly: Screw metal or nonmetallic materials on the formation of high strength, wear resistance, with interchangeable standard thread. Aluminum, copper, titanium, magnesium alloy, the low strength of engineering materials can significantly improve the strength and wear resistance; applications in steel, stainless steel, cast iron, you can prevent a variety of vibration caused by the screw loose in.
2.Service: Thread processing error or repair damaged threaded holes, use the wire thread insert as a means of repair, you can not increase the weight and volume to get the economy to maintenance, to save the important parts, quickly and efficiently repair to its original state, and still using the original specifications screws, and meet or exceed the original design requirements.
3. Transform: Helicoil sets international standards ← → Imperial ← → unified thread series of threaded holes conversion, very convenient, fast, economic, applicable to imports and exports.
