Introduction and application of key locking threaded inserts

1.what is the key locking thread insert

key locking thread insert is a kind of special fastener with internal and external threads and 2 or 4 bolt keys on the external thread. The key locking thread insert is inserted into the bottom hole after tapping, and then 2 or 4 bolts are pressed into it to play a strong fastening role. Products are mainly used in aerospace, railway locomotives, vibration machinery and electronics and other products with higher thread strength requirements

2.key locking thread insert features

a, key locking thread insert is usually made of stainless steel material made of high strength thread insert, and passivated according to relevant standards, standard products including metric thread size, inch thread size and special thread size, etc., can be customized according to actual needs.

b, key locking thread insert can be used in alloy, light materials, steel and cast iron and other low-strength materials, in order to increase the strength of the thread; Can also be used to repair thread, damaged thread repair can still use the same specifications of the original bolt.

c, key locking thread insert because of its effective mechanical key, it can control the rotation and rotation of the product. The mechanical key pins are 2 or 4 and are built into the key slot of the external thread before assembly.

d, key locking thread insert is especially suitable for application in the need of high strength internal thread environment, seismic, strong drawing resistance. Higher strength than ordinary steel wire screw sleeve, firmly connected with the matrix, in the impact or vibration environment will not be removed from the matrix.

3. 3.key locking thread insertclassification

a, key locking thread insert from the bolt locking function can be divided into ordinary type and locking type 2.

b, key locking thread insert from the form of internal thread can be divided into metric system and British system 2.

c, key locking thread insert from the size of the external thread can be divided into thin-wall type, heavy, extra heavy, and so on, as well as British miniature, solid body, and British internal thread metric external thread, metric internal thread British external thread and other forms.
