Hand tools market positioning Aerospace level ： It is higher than industrial level to request products quality with the strict way. DIY level ： It’s for general use. Professional level ： It’s the basic level of professional hand tools. Industrial level ： It is higher than professional level to request higher product quality.

The difference between Hexagonal and 12 angular The difference between Hexagonal and 12 angular points on the socket ： 1. Timing: The hexagonal is traditional shape, but the 12 angular is later than Hexagonal. 2.Function ： The angle of 12 angular are the double angles of hexagonal. When you used the wrench to put into screw, the hexagonal wrench needs 60 angle, but 12 angular wrench needs 30 angle. (As figure) 3.Size ： The functions and size of the 12 points type is the same with the 6 points type and its inner part is serrate. It can be fitted with the screw’s head or bolts more closely, its shape looks like plum blossom, so it also known as plum blossom type. The red frame is hexagonal and the black frame is 12 angular.

What is the function of the wrench’s angle? 0 °,15 °,45 °, 75° To choose various angle wrenches is mainly based on using places or the depth of the screws in the machines. Description ： If the users used the tool non-smoothly, it might be caused the space limited or machine’s location problem. In order to use the tools conveniently, we design various angle wrenches when we produced them.

The 0° or 15 ° of Wrench is suitable for disassembling the screws without depth. If there is a little depth for its screws, the user can’t use with 15 ° wrench. The user may need to choose its angle of wrench according to how’s depth of its screws.

What is the difference of the teeth application for ratchet ? Due to the different number of teeth, the main difference is the angle of rotation. The circle is 360 degrees. When the numbers of teeth is bigger, each tooth is assigned to the smaller angle. (As figure) For example, When the head of ratchet is 72 teeth, the angle of each tooth is 5°. In other hand, when the head of ratchet is 24 teeth, the angle of each tooth will be 15°.

Advantages and disadvantages: The users set ratchet into screw or socket when they used it. They usually turn the body of ratchet to use it. If the angle of teeth is smaller, then you can use less force on turning its angle. When repair technician fixed the car in a narrow place, he can’t use bigger turning angle. However, the advantage of ratchet head has less teeth: The structure of driver and pawl contradict each other. (As Figure) The teeth are lesser, so the structure is more stronger.

The types of Bit/Bit socket The using ends divide into 8 type: PHILLIPS SLOTTED POZIDRIV HEXAGON TORX -TAMPER RESISTANT RIBE BIT Socket TORX-TAMPER Internal XZN SQUARE

The ratchet of Quick-release The ratchet has two using functions that divide into PUSH and NO PUSH.( As figure)

The sockets add the friction with handle and ratchet when setting sockets doesn’t shake, so they process bead groove in the square hole. The bead groove of sockets gets stuck the bead of connector. The PUSH and NO PUSH buttons of ratchet are designed for the bead groove.

PUSH function The ratchet has direction button which controls the clockwise and counterclockwise and circle button which uses to set or disassemble sockets. These are two functions: 1. The steel ball will sink when you press the circle button, so it can reduce the resistance to set the socket. 2. The socket can’t be taken off if you don’t press the circle button, so it can prevent the socket falling and causing an accident. (Picture 1) The steel ball will sink when you press the circle button.

(Picture 2) It is convenient to set the socket. The socket can’t set into the ratchet when you don’t press the button. (Picture 3) When you don’t press the button, you can’t take off socket from the ratchet. (When working on the high altitude, it can prevent from socket dropping and causing danger.)
