2020 New Arrivals Screw Tap

2020 New Arrivals Screw Tap Description:

Screw tap specially used for wire Thread Insert

Screw tap is used for processing the special inner screw of the threaded hole,structural size according to the national standard ''fine handle machine and handmade tap''GB3464-83’s requirement manufacture,the material is high speed steel,which can be used by machine and handmade both.According to the application,it can be divided into three kinds: light alloy machine or hand tap,ordinary steel machine or hand tap and Special Tap.

Product Features

A.The diameter of the wire thread in the daily life is slightly larger than the diameter of the threaded hole. When the assembly is made, the wire thread is screwed through the installation of the wrench thread. The guide ring is twisted to make its diameter smaller and screw in the wire In the internal screw hole, after the installation, the wire screw sleeve produces a similar spring expansion effect, so that it firmly fixed in the screw hole, not move with the screw’s movement.

B.Increase the load capacity and fatigue strength of the threaded connection:the Wire Thread Insert forms a flexible connection between the screw and the bottom hole of the internal thread,and this method eliminated the distance between the internal thread and the external thread and the error in half of thread angle.The load on each thread can be evenly distributed on the specified length,thus strengthening the internal thread and damping, so the fatigue strength of the threaded connection can be improved.

C.wear-resistant:the wire thread insert spiraled by the extremely hard cold rolled stainless steel wire,surface hardness can reach HRC43 ~ 50, the surface of the wire diameter (precision can be up to 2 ~ 4 m) to reduce the friction and wear,it can turn the torque decreased by 90%, which is made up by the screws friction,and with minimal tighten screw torque moment and got the biggest preload bolt tension, prevent the screw loose, make all kinds of materials and levels of screw in the best state.

D.Corrosion resistant:Because of the excellent corrosion resistance of the wire thread insert, it can ensure its practicality in the most materials and the usual environment conditions, the parts of wire screw inserts will not rust.

E.Save material:Compared with the internal thread without the wire thread insert,under the same intensity condition,using the wire thread insert can make more fully use of the yield limit,you can choose the smaller size and higher strength bolt, it can achieve the maximum use of materials,reduce weight and volume.

F.The screw Lock Inserts can lock the screw in the threaded hole tightly, they can make the screw not loose and fall off in the shock, better than the normal locking device.The Screw Lock Inserts are able to recovery and allowed for multiple removal of torque without reducing the thread,it can be reused.

G.It can maximize the design flexibility, widen the selection range of design, simplify structural design and assembly, for example, it can replace bolt nut and make the connection easier.
