1 Wear resistance: Rebar couplers are precisely wound by extremely hard cold-rolled stainless steel wire, which reduces friction and abrasion, and can reduce the torque generated by friction on the screw by 90%, so that it can be obtained with the smallest screw tightening torque. The maximum pre-tightening torque and screw tension prevent the screws from loosening and make the screws of various materials in the best use condition.

2 Corrosion resistance: Due to the excellent corrosion resistance of stainless steel wire threaded sleeves, Rebar couplers can ensure their performance under a variety of materials and normal environmental conditions. The assembly of Rebar couplers will not stagnate and rust.

3 Heat resistance: Rebar couplers can prevent the threaded connection from jamming or scratching at high temperatures.

4 Save materials: Compared with ordinary standard internal threads, under the same strength conditions, after using Rebar couplers, in order to make the best use of the yield limit, small size and high strength screws can be selected, so that a large number of screws can be used. Save materials, reduce weight and reduce volume.

5 Rebar couplers can lock the screw in the threaded hole, and can prevent the screw from loosening and falling off when subjected to vibration and impact, which has better process performance than the usual locking device. Rebar couplers have multiple disassembly and assembly without reducing the torque of the thread, and they also have high reusability.
