Q:How to distinguish between good and bad wrenches?
Key points to distinguish a wrench from good or bad1. shall not rust, burrs, cracks and spots, etc.;2., the mouth symmetry, laser lettering should be clear;3. hardness to reach the required standard, and to accurately position4., flexible wrench operation of the turbine to be flexible, pin can not be loose.
Q:TOHNICHI torque wrench, where to introduce the use of it?
Check calibration a torque wrench using Nitto million times or a year, in order to ensure its accuracy.Japan, torque wrench warranty period for 180 days. Misuse, abuse, excessive use and collision are not within the scope of use.
Q:What are the differences between electric wrench, pneumatic wrench and torque wrench?
The first set a torque limit when the applied torque reaches the set value, the wrench will be issued a "Kata" sound or a wrench bend at the joint point of this representative has not the fastening force. The pneumatic plate hand can be sized at each of the standard ratchet socket drives, from small 1/4, drive tools, group loading and disassembly to 3.5. The pneumatic wrench is not suitable for fastening the device body and is used for fastening the installation parts of ceramics and plastics. The working principle of torque wrench torque wrench (spanner) issued a sound principle Kata is very simple, can be divided into the following steps: 1, torque wrench to understand the issue of "Kata" sound after the prompt you has reached the requirements of the torque value; a torque wrench 2, "Kata" is produced by itself the torque release structure, its structure is divided into pressure spring, torque release joint, torque rod structure composed of three to 3, first in the torque wrench to set the desired torque value (set by the spring on the push rod to release joint torque pressure), locking torque wrench to tighten the bolts. When the bolt reaches the torque value (when the torque is greater than the pressure of the spring), it will produce an instantaneous disconnection effect. In effect generated from a sudden joint percussion, a wrench of the metal shell "Kata" sound. This confirms the reminder of the torque value (in fact, as in our elbow joint, which is bent at 15 degrees, placed in the iron tube and then touched by a straight line.
Q:I wonder if there are any differences between digital display torque wrenches and non digital ones. Where do you sell them?
The digital torque wrench is an upgraded version of the dial type torque wrench. The accuracy is higher than the dial plate, and the operation is simpler! Digital torque wrenches are generally referred to as preset wrenches for assembly and fastening purposes
Q:How do you use the six point spanner?
Common inside six corners screws, if this is the screw, six edges of the six angle wrench can be used.
Q:What problems do sleeve wrenches use?
The socket wrench is used for detecting the tightening torque value of the steel connecting sleeve and the connecting wire head of the steel bar.Steel joint sleeve torque wrench applicable range: This product applies to the diameter of 12- 40MM mm rebar connection, tightening torque test.Steel connecting sleeve torque wrench technical indicator: indication duty error / indication repetition error is less than or equal to 0.5%.Torque wrench for steel connecting sleeve specification: wrench arm arm length 600mm. Torque value setting range 70~370N.M.
Q:What is a stall type hydraulic pulse pneumatic tool?
Stall type hydraulic pulse wrench is different from the percussive start wrench, percussive pneumatic wrench, pneumatic motor driven hammer strike block rotation, easy to cause harm to the bolts, the torque fluctuation is relatively large, but not easy to set twisting speed.The stall type wrench is relatively accurate through constant rotation and constant torque.
Q:What's the difference between a wrench T15 and a 15IP?
Size is different, T15 is phi 3.5*23*66, 15IP is phi 3.5*45 and handle width 40
Q:Inside six angle spanner, black is good or white is good, why some have black, I prepare to buy, but don't know to buy what kind of color
Buy six angle wrench on the main material from the durability of S2 (foreign domestic steel grades like CR-V called CR-Mo) the best of the worst carbon steel heat treatment process at the level of the general election a big brand, you can choose from low to high.
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.
