Q:How to change the type of adjustable spanner?: The utility model is also called a live wrench, and is a tool for screwing or loosening an angle screw or nut. Electrician commonly used 200, 250, three 300mm, the use should be based on the size of the nut matching.

Q:What are the two purpose wrenches?: Standard for manufacture of dual-purpose wrenches: GB/T4392-1995 (percussion wrenches and percussion wrenches). Features: dual wrench and spanner by high-quality carbon steel or alloy steel forged into a whole, has the advantages of reasonable design, stable structure, high density material, anti attack ability, do not fold, constantly, bending, product size precision, durability and other characteristics.

Q:What is the torque tolerance of a wrench?: Torque (Torque, also known as torque) in physics is a special moment, is the product of the force and force arm, the international unit is Nm nm, also can see the KGM lb-ft, such as G=mg, torque, when g=9.8 1kg, the weight is 9.8N, so 1kgm= 9.8Nm, while the pound feet lb-ft is the imperial torque unit, 1lb=0.4536kg; 1ft=0.3048m, 1lb-ft=0.13826kgm can be calculated. In everyday expression, torque is often referred to as torque (in physics, these are 2 different concepts). For example, the torque of the 8 generation Civic 1.8 is 173.5Nm@4300rpm, which means that the output torque of the engine at 4300 revolutions per minute is 173.5Nm. How can the force of 173.5N drive 1 tons of cars? In fact, the engine torque will be magnified (at the same time reduce the speed), this will depend on the transmission, the final transmission and the tire. The release of the first engine torque through the transmission "adjustable" to end transmission torque amplification (for further amplification in the year-end party) (at the same time, to further reduce the speed) finally released the driving force of tire. If a car 1 speed gear ratio (the number of teeth of the gear ratio, is the essence of gear radius ratio) is 3, year-end party 4, tire radius of 0.3 meters, the original torque is 200Nm, the last in the axle torque to 200 x 3 x 4=2400Nm, divided by the tire radius of 0.3 meters, friction the tire and the ground part is 2400Nm/0.3m=8000N, that is the driving force of 800 kg, which is enough to drive a car.

Q:Electric bicycle, bicycle wrench, wire wrench, how to use it?: If you really use, it is easy to handle, the corresponding wrench openings directly onto the spokes, clockwise is tight, anti clockwise is loose, try several times will be

Q:Volkswagen Polo wrench and suggest how to remove oil?: If you have just finished maintenance, there are still small wrenches in the flash, according to the following steps performed:1. Insert the key (do not rotate);2. Press the reset button on the instrument panel (press and hold);3, turn the key to electrify or start the car (do not put the reset button until the small wrench disappears).

Q:Release the tap. Does the wrench turn counter clockwise or clockwise?: A pretty sure sign. You said it basically right, and the wrench was going in an anticlockwise direction. When confronted with such a problem, be calm and think carefully. Others give you the knowledge of your reference. Try to understand it by your own mind.

Q:What problems do sleeve wrenches use?: Methods: with special wrench precision adjustment key is inserted into the tail end hole Neishun Zhuanzeng clockwise torque value, counterclockwise rotation to reduce torque value.

Q:What are the differences between electric wrench, pneumatic wrench and torque wrench?: The pneumatic hand wrench, also known as the ratchet wheel, hand and power tool assembly, is primarily a tool for providing high torque output with minimal consumption. It allows a mass object to rotate at a constant speed through a constant power source, and then instantaneously hits the output shaft so that a relatively large torque output can be obtained. Compressed air is the most common source of power, but there are also electric or hydraulic ones.

Q:What do you mean by the 6.3 and 12.5 series of socket wrenches?: Socket wrench 6.3, (6.3MM) 1/4 inch, socket wrench 12.5 (12.5MM) 1/2 inch.

Q:Which kind of material is good for inner six angle spanner?: Inside the six angle wrench, the best material is S2, followed by 8660. The market is the conventional carbon steel and chrome vanadium steel, chrome vanadium steel in corrosion resistance, hardness and wear resistance than carbon steel, so that the choice of chrome vanadium steel.
