In order to unscrew a rusty bolt using a wrench, one can _______________.

1) Apply lubricant to the bolt
2) Use a hammer to loosen the bolt
3) Use pliers to grip the bolt
4) Use a screwdriver instead of a wrench

Answer 1

To unscrew a rusty bolt with a wrench, you can apply lubricant, use a hammer to loosen it, or use pliers for extra grip. Mechanics also sometimes extend the wrench handle with a pipe for more leverage, although this can be risky.

Step-by-step explanation:

In order to unscrew a rusty bolt using a wrench, one can:

• Apply lubricant to the bolt to reduce friction and make the bolt easier to turn.
• Use a hammer to gently tap the wrench. This vibration can help break the rust bond between the threads of the bolt and the surface it's attached to.
• Use pliers to grip the bolt head more securely, providing additional leverage.
• Use a screwdriver instead of a wrench is not relevant here, as screwdrivers are used for screws rather than bolts.

Mechanics sometimes put a length of pipe over the handle of a wrench when trying to remove a very tight bolt. This provides greater leverage by extending the handle of the wrench, which in turn increases the torque applied to the bolt. However, this can be hazardous as it can also break the bolt if too much force is applied.
