Allen wrenches
source:Industry News release time:2021-06-29 Article author:Rosit Popular:Air band saw
Allen wrenches reflect the important difference between Allen wrenches and other common tools (such as flat-blade screwdrivers and Phillips screwdrivers). It exerts force on the screw through torque, which greatly reduces the strength of the user's force.
The specifications of metric allen wrenches are: 2, 2.5, 3, 4, 5, 6, 7, 8, 10, 12, 14, 17, 18, 22, 24, 27, 32, 36 (mm).
adjustable wrench
Adjust the size of the opening so that the jaw face of the wrench is close to the face of the nut or bolt. When working, work hard toward the vice jaw of the wrench and hold the other end of the wrench in your hand, so as to avoid damaging the wrench with too much force.
The arm should be perpendicular to the direction of the wrench as much as possible, which will save effort. When using a wrench, do not pull the wrench with both hands at the same time. Only one hand can be used forcefully, and the unforced hand must have a support, and the footsteps must be T-shaped and stand firmly to prevent the operator from slipping off the wrench during the process of exerting force. A personal injury accident occurred due to a fall.
Open-end wrenches (open-end wrenches), socket wrenches, lock wrenches and allen wrenches are called special wrenches. Its characteristic is that the single head can only screw one size of screw heads or nuts, and the double head can only screw two sizes of screw heads or nuts.
When using a dead-end wrench, make sure that the opening of the wrench is matched with the screwed part and then apply force. If the contact is not good, it will slip easily and cause the operator's body to lose balance; When the torx socket and wrench handle are deformed or cracked, stop using it, and pay attention to removing the dust and oil in the socket at any time; when using the lock wrench and allen wrench, pay attention to selecting the appropriate specifications and models to prevent slippage and damage. hand.
