Bolt tightening device for the torque wrench, the opening size of the various shapes of fixed wrench, the opening variable size of the movable wrench, hydraulic tight bolts need hydraulic pumps and other accessories. In short: fasteners with screwdrivers and hexagonal tools are screws, and fasteners with wrenches are bolts. Note: can not be distinguished by the size and length of the nominal diameter. For example, a M48 long 300mm cylindrical head fasteners, GB / 70.1-2008 standard will be defined as hexagonal head screws, not bolts.

(2) with a small amount of 502 glue into the screw hole, and then screw into the screw, and so the glue after the solid tip and then use the tip of the screw to pull out the screw (only the screwdriver is not afraid of causing screw teeth). (3) fruit screw cap exposed, you can use the tip of the clamp clamp screw cap after the screw. (4) the general mobile phone screws are metal, the case is plastic, not screw down when the time. You can use the tip of the screw into the screw cap, the metal screws to screw the plastic around the plastic melting, with the tip of the clamp clamp, gently pull out! You can also force down the screws about 1 mm (be careful not to engage in the chassis), you can solve the problem of loose screws. (5) so little the screw is not easy to get, my father had to repair the original bike screw method, with a small electric drill in the middle of the screw to play a not deep hole, and then find an anti-silk tap into the (must Anti-wire tap, it is difficult to find, to go to a large measuring blade cutting shop), you can unscrew the.

Q: How much is a screw?: To see what screwdriver, if it is a small screw, and then you buy more words, a single cost may be a few cents, if it is a single purchase may be more expensive.
