FAQ

The process of making an ordinary open-ended wrench requires material and heat treatment

The blank after the rough machining after quenching, good milling opening angle of 780 DEG C after heating, in salt water (local spanner mouth) quenching, tempering 250 DEG ~350 deg. This will ensure that the wrench has a certain degree of hardness, wear and tear does not hurt the nut, wrench the rest of the parts have a certain toughness, can withstand torsion load. (machining process omitted)

How to distinguish between screw size corresponding to the big wrench?

A full set of six angle wrench, minimum specification of 3, and its corresponding relationships for S3=M4, S4=M5, S5=M6, S6=M8, S8=M10, S10=M12, S12=M14-M16, S14=M18-M20, S17=M22-M24, S19=M27-M30, S24=M36, S27=M42.

What do you mean by a wrench icon on the dashboard of Chery?

It is maintenance of lights, is to remind you to do the maintenance, if you have no time to maintain, can not control him, for you do not affect the normal traffic, the next time the maintenance to the maintenance personnel to help you eliminate it.

Manufacturing process of inner six angle wrench

Say so complicated, don't die ah, very simple selection of high manganese steel forged six edges, the corresponding length of heating, bending, pickling rinse, dark red (500--700) oil quenching, nonscale is natural black, here is the finished product, the high cost of plating is not good to sell, because people are feeling good is black, here we have a factory is doing business good, very cheap to sell a few dollars a kilogram

What's the maximum torque of manual torque wrench?

Torque wrench is a kind of wrench. Generally divided into: electric torque wrench and manual torque wrench two categories. Torque wrench can be both tight and tight, and its use is to adjust the torque, and then tighten the bolts. Torque wrench is the most important feature for the national standard, big six angle, high-strength bolts for M16, M20, M22, M24, M27, M30 and so on. General for fastening bolt must first end tight and tight, and each need to have strict requirements of torque.

It's powerful. Why isn't the wrench strong?

Of course you don't help. Forearm length has more advantages. In addition, the size of muscle strength is not everything, muscle fibers, not muscle volume, you can do some exercise muscle fibers. These are not personal experience, please point out.

What is the ball head at the end of the ball head L type six angle wrench?

You can use the ball head when the screw and the inner six angle wrench can not be placed in a straight line.

When tightening the bolt with a wrench, can the tail of the wrench be lengthened?

The principle is not a wrench lever principle, because the spanner is rigid tool, it in the bolt on the torque locked, the torque is equal to the force multiplied by the arm, can increase the length of the same size to force greater torque wrench in the back, but the wrench length is calculated according to the yield strength, it the bending strength, if the increased strength of potential blindly, will substantially increase the tightening torque, can easily destroy the threads of the wrench opening also easy to cause damage.
