Last updated: February 21, 2024

Spanner sets typically consist of a variety of spanners in different sizes and types, all housed in a single package. These sets are designed to provide users with a range of options for different tasks, ensuring they have the right tools for the job.

Spanner sets are convenient for professionals and DIY enthusiasts alike, providing a comprehensive selection of tools in one package. They offer versatility, efficiency, and organisation for various mechanical and automotive tasks.


 What is a Spanner?

A spanner is a metal tool whose end fits round a nut so that you can turn it to loosen or tighten it. Spanners, including combination spanners, are size-specific tools with both closed and open ends. The small head shape allows them to manoeuvre in tight locations, lowering the chance of rounding. Fixed sizes reduce the need for frequent modifications, resulting in faster, more pleasant work. Other versions, such as double box or offset spanners, increase adaptability for a variety of applications.


What are spanners used for?

A spanner is a handheld tool designed for gripping and tightening or loosening fasteners. It provides mechanical leverage to apply torque, facilitating the turning of rotary fasteners such as nuts and bolts. Widely used across industries, they play a crucial role in tasks such as automotive repairs, construction, machinery maintenance, plumbing, household repairs, bicycle and motorcycle maintenance, as well as in mechanical, electrical, and agricultural applications. Spanners provide a secure grip, making them essential for ensuring the proper assembly and maintenance of various components in different settings.


 Some of the different types of spanners 

Double-ended spanner sets

A double-ended spanner is a versatile hand tool designed with two different-sized ends for tightening or loosening nuts and bolts. Each end has a different size offering convenience and efficiency in tasks where multiple sizes may be encountered.

Box Spanner sets

A box spanner is a specialised tool with a hollow, cylindrical head featuring openings on both ends. It provides a closed grip around nuts and bolts, making it particularly useful in confined or tight spaces. This design allows it to fit over fasteners completely, offering a secure grip. Box spanners are commonly used in automotive and mechanical applications, especially in situations where space is limited. For those who need a box spanner set, they are usually manufactured from carbon steel and zinc coated to prevent corrosion.

Combination spanner sets

A combination spanner is a versatile tool designed for turning nuts and bolts. It features two distinct ends: an open-end and a closed-loop end. The open end is U-shaped, allowing for quick engagement with fasteners in confined spaces. On the other end, the closed-loop provides a secure grip around the fastener, minimising the risk of slipping and allowing for increased torque application. This dual-ended design makes combination spanners adaptable for various applications, making them a valuable addition to toolkits for tasks in automotive, mechanical, and household settings. Available in different sizes, they cater to the diverse dimensions of nuts and bolts.

Ratchet Spanner sets

A ratchet spanner is an innovative hand tool designed for convenience and efficiency in turning nuts and bolts. It features a mechanism that allows the user to rotate the tool in one direction while keeping it engaged on the fastener in both directions. This means that the spanner doesn’t need to be removed and repositioned for each turn, making it particularly useful in confined spaces where a full swing is not possible. The ratchet mechanism operates similarly to a gear, with a handle that can be moved back and forth without disengaging from the fastener.

How to identify an M Bolt?


Are spanners and wrenches the same?

The terms “spanner” and “wrench” are often used interchangeably, though they have distinct meanings based on regional variations. Generally, a wrench is a broad term encompassing various tools used for turning objects, including adjustable wrenches, pipe wrenches, and torque wrenches. In contrast, a spanner specifically refers to tools with open-ended or jaw designs tailored to fit nuts or bolts; the head of a spanner tends to be slimmer than a wrench, making it easier to fit into narrow spaces.


When were spanners invented?

Spanners developed in the 15th century as box spanners for winding crossbow strings. Their use in wheel-lock weapons dates back to the 16th century. By 1825, the Industrial Revolution had led to standardisation, with cast iron spanners being mass-produced. Sir Joseph Whitworth’s improvements in the nineteenth century increased accuracy. The Whitworth standard gained popularity during the Industrial Revolution, and World War II saw the introduction of a modified British Standard (BS) to conserve metal.

In the 1970s, Britain adopted the metric system, which replaced imperial spanners. However, imperial spanners are still required due to the continued usage of pre-1970s equipment.

How are spanners made?

Spanners are crafted through drop forging, involving heating steel billets, shaping them with dies, and stamping details with a hydraulic press. Angled heads are shaped by a machine, and milling and broach machines are used for specific heads. Box and spark plug spanners are made from shaped steel tubing. After tempering, flare nut heads are created by cutting a section out. Plating options include electroplating and black oxide for corrosion resistance. Rust inhibitor solutions and strength testing are applied for protection and quality assurance.

Common types of spanners include open-end spanners, box-end spanners, combination spanners (which have both open and box ends), adjustable wrenches, and socket wrenches. Each type is designed for specific applications and preferences.

How do I choose the right size of spanner for a nut or bolt?

The right size of the spanner is crucial for effective use. Match the size of the spanner to the size of the nut or bolt you are working with. Using the wrong size can damage the fastener and the tool.
