From open-end spanners to ring spanners, combination spanners to adjustable spanners, we’ll break down the different types of spanners and their uses. We’ll also share some tips on how to choose the right size and quality of spanner, so you can get the job done quickly and efficiently.

What are spanners?

Spanners can be defined as the tools that are used for gripping and fixing nuts and bolts. They generally have a fixed jaw. Some also have an adjustable jaw that can be opened or closed using a sliding mechanism.

Types of spanners

There are several types of spanners available in the market, each designed for specific purposes. Here are the most common types of spanners you’re likely to come across:

Open-End Spanners

Open-end spanners are the most common type of spanner used in most households. They have a U-shaped opening at one end that is used to grip the nut or bolt. Open-end spanners are ideal for use in tight spaces where a closed-end spanner would be difficult to use. However, they only grip two sides of the nut or bolt and can slip if the nut or bolt is rusted or rounded off.

Ring Spanners

Ring spanners are also known as box spanners. They have a circular opening at one end that completely encloses the nut or bolt. This design provides a better grip on the nut or bolt and reduces the risk of slipping. Ring spanners are commonly used in automotive and mechanical applications where a higher torque is required.

Combination Spanners

Combination spanners are open from one end and a ring spanner on the other. This design provides the best of both worlds and makes them versatile and convenient to use. Combination spanners are ideal for use in situations where a ring spanner is too big and an open-end spanner is too small.

Adjustable Spanners

Adjustable spanners, also known as crescent wrenches, are a versatile type of spanner that can be adjusted to fit nuts and bolts of different sizes. They have a movable jaw that can be adjusted using a thumbwheel or a screw mechanism. Adjustable spanners are ideal for use in situations where you don’t have the right size of spanner or if you’re working with nuts and bolts of different sizes.

Uses of Each Type of Spanner

Each type of spanner has its own use, depending on the nature of the job. Here’s a breakdown of the uses of each type of spanner:

Open-End Spanners

Open-end spanners are ideal for use in tight spaces where a closed-end spanner would be difficult to use. They’re also useful for working with nuts and bolts that are not rusted or rounded off.

Ring Spanners

Ring spanners are commonly used in automotive and mechanical applications where a higher torque is required. They’re also useful for working with nuts and bolts that are rusted or rounded off.

Combination Spanners

Combination spanners are versatile and convenient to use. They’re ideal for use in situations where a ring spanner is too big and an open-end spanner is too small.

Adjustable Spanners

Adjustable spanners are a versatile type of spanner that can be adjusted to fit nuts and bolts of different sizes. They’re ideal for use in situations where you don’t have the right size of spanner or if you’re working with nuts and bolts of different sizes.

Factors to Consider When Choosing a Spanner

Choosing the right spanner for your project is important to ensure that you get the job done quickly and efficiently. Here are some factors to consider when choosing a spanner:

Size

The size of the spanner is the most important factor to consider when choosing a spanner. You need to choose a spanner that fits the nut or bolt you’re working with. Using a spanner that is too small or too big can damage the nut or bolt and make it difficult to remove.

Quality

The quality of the spanner is also an important factor to consider. A high-quality spanner is made of durable material that can withstand heavy use without breaking or deforming. It’s better to invest in a high-quality spanner that will last longer than to buy a cheap spanner that will break or deform after a few uses.

Material

The material of the spanner also affects its quality and durability. Spanners made of high-quality steel or chrome vanadium are more durable and resistant to rust and corrosion. Avoid spanners made of low-quality materials like aluminum or low-grade steel, as they can break or deform easily.

How to Select the Right Size of Spanner for Your Project

Choosing the right size of spanner is crucial to ensure that you get the job done quickly and efficiently. Here’s how to select the right size of spanner for your project:

  • Measure the nut or bolt you’re working with using a ruler or a caliper.
  • Choose a spanner that matches the size of the nut or bolt. The size of the spanner is usually marked on the spanner itself or on the packaging.
  • Test the spanner on the nut or bolt to ensure a good fit. The spanner should fit snugly without slipping or wobbling.

Tips for Maintaining Your Spanners

Taking care of your spanners is important to ensure that they last longer and perform better. Here are some tips for maintaining and caring for your spanners:

  • Keep your spanners clean and dry to prevent rust and corrosion.
  • Store your spanners in a dry and secure place to prevent them from getting lost or damaged.
  • Use a rust inhibitor or a lubricant to protect your spanners from rust and corrosion.
  • Don’t use your spanners as hammers or pry bars, as this can damage the spanner and make it unsafe to use.
