Selecting the Right Vise Grips
Vise grips, also known as locking pliers, are versatile tools that can be used for a wide range of tasks, from gripping and clamping to cutting and twisting. When selecting the right vise grips for your needs, it is important to consider the following factors:
Jaw Capacity
The jaw capacity refers to the maximum width that the jaws can open. This is an important consideration, as it will determine the size of the objects that you can grip with the pliers. Vise grips are available with jaw capacities ranging from 7/16 inch to 6 inches. For most common tasks, a jaw capacity of 1-1/2 inches to 2 inches will suffice. However, if you need to grip larger objects, you will need to choose a vise grip with a wider jaw capacity.
Jaw Style
The jaw style refers to the shape of the jaws. There are three main types of jaw styles:
- Straight jaws are the most common type of vise grip jaws. They are suitable for gripping flat objects, such as pipes, bolts, and nuts.
- Curved jaws are designed for gripping round objects, such as wires and cables.
- Needle-nose jaws are long and narrow, making them ideal for gripping small objects in tight spaces.
Locking Mechanism
The locking mechanism refers to the way that the pliers are locked in place. There are two main types of locking mechanisms:
- Trigger release locking mechanisms are the most common type. They feature a trigger that releases the jaws.
- Screw-type locking mechanisms use a screw to lock the jaws in place.
Trigger release locking mechanisms are easier to use, while screw-type locking mechanisms are more durable.
Adjusting the Jaws for a Secure Hold
Fine-tuning the jaws of your vise grips is crucial for achieving a secure hold. Follow these steps to adjust them precisely:
1. Open the Vise Grips:
Press the release lever to widen the jaws. Insert the object you want to grip between the jaws.
2. Hand-Tighten the Adjustment Screw:
Turn the screw located at the base of the jaws hand-tight until you feel resistance. This preloads the jaws, providing a secure hold.
3. Use the Jaw Adjusting Screw:
Fine-tune the jaw position using the jaw adjusting screw. Turn the screw clockwise to close the jaws further or counterclockwise to open them wider.
4. Tighten the Release Lever:
Once the jaws are adjusted, securely tighten the release lever to ensure the jaws remain in place. This is especially important when gripping objects subjected to high force.
5. Check the Grip:
Apply a slight force to the object to ensure it is held securely. If necessary, fine-tune the adjustment until you achieve the desired hold.
6. Types of Jaw Adjustments:
| Jaw Type | Adjustment | Suitable for |
|—|—|—|
| Straight Jaws | Universal | Gripping flat surfaces, edges, and irregular shapes |
| Curved Jaws | Curved to match cylindrical objects | Gripping pipes, rods, and other circular shapes |
| Offset Jaws | Angled to reach tight spaces | Gripping objects in confined areas |
Using Vise Grips as Locking Pliers
Locking Vise Grips for Secure Clamping
Vise grips are versatile locking pliers that provide a reliable grip on objects of various shapes and sizes. To use them effectively as locking pliers:
- Adjust the Jaw Width: Loosen the adjustment screw on the pliers and slide the lower jaw along the handles to fit the object you want to grip.
- Position the Jaws: Place the object between the jaws and align them to ensure a secure hold.
- Tighten the Adjustment Screw: Retighten the adjustment screw to secure the jaws and prevent them from slipping.
- Lock the Handle: Press the trigger on the top handle to lock the pliers in place. This will prevent accidental release and ensure a firm grip.
Additional Features of Vise Grips Locking Pliers
In addition to locking functionality, vise grips offer several other features that enhance their versatility:
Versatile Jaw Designs
Vise grips come with a range of jaw designs, including straight, curved, and offset jaws. These different designs allow for a wider range of gripping applications, such as holding round objects, gripping at angles, or reaching into tight spaces.
Non-Marring Jaws
Some vise grips feature non-marring jaws that prevent damage to delicate surfaces. These jaws are particularly useful for gripping polished or painted objects.
Ratcheting Mechanism
Vise grips with a ratcheting mechanism allow for quick and easy adjustments, making them suitable for tasks where frequent tightening is required.
Quick-Release Lever
For added convenience, some vise grips feature a quick-release lever that allows for instant disengagement of the jaws. This lever is particularly useful when needing to release the object or adjust the grip quickly.
| Feature | Benefits |
|---|---|
| Straight Jaws | Gripping flat or round objects |
| Curved Jaws | Gripping curved objects or at angles |
| Offset Jaws | Reaching into tight spaces or gripping at angles |
| Non-Marring Jaws | Preventing damage to delicate surfaces |
| Ratcheting Mechanism | Quick and easy adjustments |
| Quick-Release Lever | Instant disengagement of jaws |
How to Use Vise Grips
Vise grips are one of the most versatile tools in a workshop or toolbox. They can be used for a variety of tasks, from clamping and holding objects to cutting and bending wire. In this article, we will discuss how to use vise grips correctly and safely.
To use vise grips, first adjust the jaws to the desired size. Then, place the object to be clamped or held between the jaws. Finally, squeeze the handles together to apply pressure. You can adjust the amount of pressure by tightening or loosening the screw on the back of the vise grips.
Vise grips can be used for a variety of tasks, including:
- Clamping objects together
