Size

Among the first things to consider when buying a nut splitter is its size. A nut splitter helps you to crack and remove stubborn and stuck nuts, but it will not work if it is not of the right size. The sizes range from one splitter to another. Some handle small nuts while others deal with larger nuts.

Check the size of the nut you want to remove before the purchase. The size of the nut will guide you on the correct size of the nut splitter. You can also choose to buy an adjustable nut splitter, which will help you deal with all nuts irrespective of their sizes. Some companies also sell several splitters of different sizes in one set.

Brand

A nut splitter may seem like a simple tool, but you need to make sure that it will serve you for long. You may not be able to distinguish a good nutcracker by just looking at it. The best way to get high-quality nut splitter is to buy from a well-known brand. Above, we have stated some of the best nut splitters you can consider buying. Read the reviews of previous buyers and see what they have to say about the tool.

Construction

Generally, nut splitters have the same design, and this confuses buyers on the better one to buy. The difference in construction depends on what materials have been used to make the splitter and the process it has gone through. A good and reliable nut splitter should have a sturdy construction that will not break after using it just a few times. Some of the best nutcrackers are constructed with heat-treated hardened and forged steel. Always choose a cracker that feels sturdy and heavy.

Design

The design of a nut splitter will determine if it will be able to get in hard to reach areas or not. Sometimes you will need to remove stuck nuts in tight areas, and you need a splitter that will easily get there. Consider the size and the design of the nut splitter before purchasing it. Small crackers seem to get in tight areas easily. However, some are made with a reversible design enabling them to get your desired cutting angle.

Pricing

When buying any tool, we are always on a budget. Nut splitters are of different costs, which could be an indicator of their quality. However, there are also low priced nutcrackers but still high quality. Do your research well and get the best nut splitter you can within your budget.

Frequently Asked Questions (FAQs)

Q. What’s a Nut Splitter?

A nut splitter is a simple tool to remove seized, damaged or over-tight nuts from bolt threads. Nuts can, at times, become truck on bolts or bolt threads due to rust or corrosion, making it impossible to remove them with spanners or sockets. A nutcracker makes it easy for you to remove these nuts without damaging the bolts or bolt threads.

There are other methods you can use to remove these stubborn nuts, but they may result in damage. A nut splitter enables you to split the damaged nuts with minimum energy and time. When you have tried all the other methods of removing a nut, but it has failed, then a nut splitter will save the day.

Q. Do-Nut Splitters Really Work?

Yes. They do work. Nut splitters enable you to remove damaged and seized nuts easily. They are the last resort after trying to remove stubborn nuts with other methods without success. The best thing about using nutcrackers is that they do not damage the bolts or bolt threads.

The basic thing you need for a successful job is to have the right tools to work along with the splitter such as wrench and sockets. The other thing is you need to have the right size of the nut splitter for the nut. Working with the wrong splitter size will not work.

Q. How Do You Split a Big Nut?

Splitting a big nut needs you to have a large nut splitter ideal for the size. Splitters will have their diameters indicated and the range of nut sizes they can handle. Once you have right nut splitter, detach the chisel and put the ring over the big nut. Place this chisel over the nut. The blade should face the nuts, flat side. At this point, start tightening the screw to clamp the nut between the inner edge of the ring and the chisel. Continue tightening the screw using a spanner, socket or wrench till the nut is split.

Q: How Do You Use a Bolt Splitter?

Using a nut splitter is quite an easy task which anyone can perform. Here are steps to observe when using a splitter to crack a nut:

Step 1: Unscrew the Chisel

Turn the head of the screw in an anti-clockwise direction pushing the chisel into the splitters handle until the nut can fit between the anvils and chisel.

Step 2: Position the Chisel

Placing the nut splitters frame over the nut, line the chisel, and avail with the flat sides of the nut. Ensure that the chisel is well situated in the center of the flat side of the nut.

Step 3: Tighten the Chisel

Tighten the chisel by turning the head of the screw in the clockwise direction. Pinch the stuck nut in between the avail and chisel of the nut splitter. Go on tightening the screw with a spanner, socket or wrench to deliver enough torque. When you hear a crack sound, it means that the nut is split, and you should stop. You may be needed to hold the nut splitter in place through the process.

Step 4: Unscrew the Chisel

Unscrew the chisel by turning the nut splitters head in an anti-clockwise direction. The chisel will dis-attach from the nut and move back into the handle.

Step 5: Repeat the Same on the Other Side

Nut splitters have one chisel, and thus you need to repeat the process to crack the other side of the nut. The nut will split into two without damaging the bolt thread.

Q. How Do You Use a Heavy Duty Nut Splitter?

Heavy-duty nut splitters are made with high-quality materials. They are sturdy, and they can handle heavy-duty tasks such as firm, thick, and stuck or stripped nuts, which no other tool can remove. A heavy-duty nut splitter just works like the other splitters.

You just need to unscrew the chisel, place the nut into position and tighten it hard with a socket, wrench or spanner until you hear a cracking sound. You should do this on both sides of the nuts for it to come out. Heavy-duty nutcrackers will spare you energy and time when working with completely stubborn nuts.

Final Words

The splitters are found in different sizes, shapes, and designs, but they all perform the same task, removing stripped or damaged nuts.
