Q:What's the difference between 21V and 25V electric wrenches?: Lithium battery energy package specifications are different, usually high voltage, energy, electricity capacity is large, the use of a charge after a long time, but the weight will increase.

Q:How are the torque wrenches KN and N.M converted?: N stands for the mechanical unit "Newton", and M is the torque magnitude of the "m", N, M, expressed by the torque of the element length, is the force of the force from the point of the distance of the known rotation axis. Rotation of torque calculation.100NM meaning: the force of 100N acts at the point of action away from its axis of rotation. 1M. Or 1N force 100M. The short is 100 1NM, and the force of 1NM 1N is applied to the 1M axis of the rotation axis.

Q:Is the inner six angle spanner bent with six angles carbon steel?: On the market, the sale of genuine products in the six corners of the hand are hot stamping process, only a very small part of shoddy products, poor workmanship, in order to save costs, is a molding.

Q:The difference between the six corners and the inner six corners of the plum blossom: The six angle bolts are divided by the head, with six bolts in the cylinder head. This is the most commonly used, and it has many kinds. It is made of iron according to the material, that is, the carbon steel and the stainless steel. Stainless steel six angle bolts also have stainless steel, SUS304 and SUS202 and so on. Half round six angle bolts, the head also called the inner six angle bolt. Countersunk six angle bolts, head is flat, and inside is the six corners. There are a variety of national standards are more special, called headless six angle bolts. Is the set screws, we often call the stop screw, set screw. This is the universal name for the headless six corner bolt, but the meaning is the same. Of course, there are also some flower shaped bolts with six angles and plum blossom heads. The use of this relatively small, the market is also basically difficult to see.

Q:What is the difference between worm gear and worm wheel?: Difference1) the worm gear is equal to the gear; the worm is equal to the rack.2) the worm is an active part; the worm wheel is the follower.3) many worm gear has an interesting feature that other gear sets do not have: the worm can easily turn the gear, but the gear does not rotate the worm. This is because the screw angle is very shallow, when the gear try rotation screw, the screw will let keep friction between the gear and the screw in situ.

Q:The inside of the six corners wrench is broken in the screw. How can you get it out?: In the six corner screw used in machinery, mainly for fastening and disassembly, not easy to slip angle and other advantages. In the six angle wrench is generally a 90 degree bend, bend one end of the long side of the short, screw with short side fastening screws, holding a long side can save a lot of power and better. One end of a long round (six cylindrical and flat angle like sphere), round head screw holes can be inserted easily in very convenient disassembly. The manufacturing cost six to six lower than the angle angle more, its advantages and the screw head (wrench force position) six. Angle thin, in some places not within the six corners can be replaced. In addition, low cost, dynamic strength of small, low precision requirement of mechanical the inner six angle screw than six angle less than.

Q:What is the difference between pneumatic sleeve wrench specification 1/2 and 3/4?: The utility model relates to a steel connecting sleeve, which is a special product used for mechanical connection of steel bars, and is divided into a cold extruding sleeve, a taper threaded sleeve and a straight threaded sleeve.(1) according to the size (mean four square size): "1/4, 3/8", 1/2 "three specifications," is the meaning of "equal to 1 inches, 25.4MM(2) according to length: long sleeve, short sleeve, E sleeve(3) press the edge: 6 corners, 12 corners(4) appearance: single channel and double channel; knurling; cylinder; nickel plating and etc.(5) use: manual and pneumatic wrench socket wrench (black chromium molybdenum) branch

Q:What's wrong with a rechargeable wrench without strength?: High strength bolts can be divided into torshear type and the big six angle two GB, torshear type high strength bolt for M16, M20, M22, M24 four, M27, M30 non GB two GB; six angle high strength bolt for several M16, M20, M22, M24, M27, M30 etc.. General for high strength bolts fastening must first end tight and tight, and each need to have strict requirements of torque. Large six angle high-strength bolts of initial tightening and final tightening must use fixed torque wrenches. Therefore, all kinds of electric wrenches are needed for fastening.

Q:What's the difference between an electric wrench 28V and an 32V?: There is no difference between 28V and 32V.
