How to use an Alligator wrench: a step-by-step guide

Step 01: Identifying the right size of the alligator wrench

When selecting an alligator wrench, it’s essential to choose the right size for the job. The wrench’s jaws should be able to fully grip the nut or bolt you need to turn. If the jaws are too small, they won’t be able to grip the nut or bolt securely.

If they’re too large, they’ll be challenging to adjust and may damage the nut or bolt. It’s also important to consider the jaw capacity, which is the maximum size that the jaws can open to. Make sure the capacity is sufficient for the nut or bolt you need to turn.

Step 02: Adjusting the jaws of the alligator wrench

Once you have the right size of alligator wrench, you’ll need to adjust the jaws to fit the nut or bolt you’re working on. This is done by turning the adjustment screw or lever. The jaws should be adjusted so that they grip the nut or bolt securely without damaging it.

Step 03: Holding and position the alligator wrench

Properly holding the alligator wrench will make it easier to use and will help prevent injury. The handle should be held with one hand while the other is used to turn the adjustment screw or lever. Position the wrench so that the jaws are parallel to the nut or bolt; this will provide the most leverage.

Step 04: Using the alligator wrench in tight spaces

Alligator wrenches are excellent for tight spaces as they can be adjusted to fit in areas that other wrenches can’t. When working in tight spaces, it’s essential to take your time and be patient. Use the adjustment screw or lever to make minor adjustments to the jaws until they fit securely.

Tips for maintaining and storing the alligator wrench

Clean the wrench after each use

Wipe down the wrench with a clean cloth to release any dirt or debris that may have accumulated during use. This will help you to prevent the wrench from rusting and corrosion.

Lubricate the adjustment screw or lever

Apply a light oil to the adjustment screw or lever to keep it moving smoothly. This type of lubricant can prevent the jaws from sticking and make adjustments easier.

Inspect the jaws

Regularly check the jaws for any signs of damage or wear. If the jaws are worn or damaged, they should be replaced to ensure the wrench works effectively.

Store in a dry place

Keep the wrench in a dry place to prevent rust. A protective pouch or case can also help to keep it in good condition.

Keep the wrench organized

Organize your tools to make it easy to find the wrench when needed. Keep it in a designated area with other wrenches and tools you use frequently.

Don’t overuse the wrench

Avoid overusing the wrench, as it can cause it to wear out faster and reduce its effectiveness.

Don’t use the wrench on stuck bolts

Using an alligator wrench on rusted or stuck bolts may damage the wrench’s jaws. Avoid using it in such situations; instead, use penetrating oil to loosen the nut/bolt before applying the wrench.

Following these tips ensures that your alligator wrench stays in good working condition and is ready to use when needed.
