M6 Thread Insert Stainless Steel 304/316L Screw Lock Thread Inserts
Thread inserts introduction
Wire thread inserts embedded in the thread holes of low strength engineering materials such as aluminum, magnesium alloy, cast iron, FRP, plastic, etc., can form standard M and MJ threads, which have the functions of high connection strength, earthquake resistance, impact resistance and wear resistance, and can protect matrix threads by spreading stress, thus greatly prolongs the service life of matrix.
In addition, the steel wire screw sleeve can also be used as a means of repair when the thread on the original substrate is tripped or disorderly teeth, without causing the whole substrate to be scrapped, and the maintenance is convenient, fast and economical.
Wire screw sleeve has been widely used in aviation, aerospace, machinery (textile special parts, water pump, diesel engine, etc.), locomotives, automobiles, instruments, molds, construction (plastic steel doors and Windows), furniture and other fields.

Thread insert features
As a kind of screw sleeve fasteners, the pre-installed internal thread has obvious advantages compared with ordinary threads:
1. Extend the service life: Because the wire thread insert is made of stainless steel and has high hardness, the life of the softer base part thread is increased by tens to hundreds of times; its strength is increased, and the phenomenon of tripping and random buckling is avoided. occur.
2. Enhanced thread connection strength: It is applied to soft low-strength alloy materials such as aluminum and magnesium, which can effectively enhance the connection strength of the thread. The ordinary internal thread of aluminum profile has a maximum tensile strength of 1394N. Thread, its minimum tensile strength can reach 2100 N.
3. Enlarge the bearing surface: it can be used for thin machine parts that require a strong connection but cannot increase the diameter of the screw hole.
4. Improve the connection conditions and increase the bearing capacity and fatigue strength of the threaded connection: Because the wire threaded sleeve is an elastic fastener, the use of the wire threaded sleeve can eliminate the pitch and thread deviation between the screw and the screw hole, so that the load is evenly distributed , Thereby improving the load-bearing capacity and fatigue strength of the threaded connection.
