Top 8 wrench & spanner tools every DIY enthusiast should own

Choosing the right wrench & spanner tools can look like a daunting task. These are the 8 types of wrenches every DIY enthusiast should have in their tool kit!

With many options in spanner & wrench tools available in the market such as open end wrenches, box wrenches, combination wrenches, adjustable wrenches, plumbing wrenches etc., choosing the right kinds of spanner & wrench tools can get confusing however, from a broader perspective, most DIY enthusiasts would ideally require only a couple of them. Here are our top 8 picks for spanner and wrench tools which we think that every DIY enthusiast should own:

1. Adjustable wrenches
2. Combination spanner
3. Ratchet wrench
4. Pipe wrench
5. Open end spanner
6. Crowfoot wrench
7. Stubby spanner wrench
8. Ring spanner

Adjustable Wrenches

These are also known as a crescent wrench and happen to be versatile hand tools used for gripping and turning fasteners (such as nuts and bolts) of various sizes. Adjustable wrenches have a movable jaw that can be adjusted to fit different fastener widths. This adjustment can me made using a screw or a thumb wheel. This allows the tool to fit multiple fastener sizes, making it more flexible compared to using a separate wrench for each size. Generally, this type of tool has a flat, open-end jaw that fits over the edges of a nut or bolt.

Some Common Uses of Adjustable Wrenches:

• This is ideal for DIY projects where you need a tool to fit a variety of fasteners, such as plumbing, electrical or automotive work.
• Their compact design allows it to work in confined or hard-to-reach areas.
• It allows you to quickly adjust the jaw size without needing to switch out tools. This enables one to save time when working on multiple fasteners of various sizes.

Combination Spanners

Combination spanners also known as combination wrenches, are those tools that have double ends (an open end and a box end) and act as two different types of spanners tools at the same time. While one end is open ended, the other end contains a ring spanner. Combination spanners generally tend to work for fasteners of one size due to the fact that both of their ends have the same size. The dual design of these wrenches makes it versatile and practical for a wide range of fastening tasks.

Some Common Uses of Combination Spanners:

• They are used for turning bolts, nuts and fasteners in automotive repair, plumbing, machinery maintenance, furniture assembly and various other DIY tasks.
• Their open-end is great for quickly loosening or tightening fasteners, while the box-end is more useful for high-torque applications, providing more grip to prevent the fastener from rounding off.

Ratchet Wrench

As its name suggests, a ratchet wrench is a type of a tool that contains a ‘ratcheting mechanism’ and a fixed square drive size. The ratcheting mechanism of this tool enables it to turn a fastener without having to constantly remove the tool to either tighten or loosen it, thus allowing for its user to use it significantly faster especially in tight spaces requiring minimal momentum.

Some Common Uses of Ratchet Wrench:

• These wrenches are often used for working on car engines, wheels and other parts where multiple fasteners need to be tightened or loosened quickly.
• They are commonly used in tasks like assembling furniture, installing appliances and other maintenance projects that involve numerous fasteners.
• Their ability to work in confined spaces makes ratchet wrenches ideal for plumbing or electrical projects where you can’t always make a full rotation with a traditional wrench.

Pipe Wrench

Arguably, one of the most important tool in a plumber’s arsenal, the pipe wrench specializes in turning threaded pipes and pipe fittings for the purposes of tightening or loosening. This tool contains custom hardened serrated teeth on its jaws which firmly hold onto the softer metals of the pipe fittings whilst providing a fair amount of grip needed to turn the pipes, despite resistance.

Some Common Uses of Pipe Wrench:

• When dealing with corroded or rusted pipes, their serrated jaws help break loose stubborn connections.
• This tool helps in installing new pipes and fittings, particularly in situations where other wrenches or tools might not provide enough torque or leverage.
• When replacing plumbing fixtures like faucets, they are useful for removing nuts or bolts that secure them.
• They are often used in the installation or repair of gas lines, as they can handle the large, threaded fittings commonly found in these systems.

Open end Spanner

Arguably one of the most well recognized wrenches globally, the open end wrenches consist of two ‘U-shaped’ openings that grip two opposite faces of the bolt or nut. This spanner is double ended and the sizes of the openings present on both ends vary. The ends tend to be oriented at an angle of around 15 degrees to the axis of the handle which allows for greater ergonomics whilst it is being utilized on a fastener.

Common Uses of an Open-End Spanner:

• This tool helps to tighten or loosen fasteners such as nuts and bolts in various mechanical, construction and automotive tasks.
• In car repairs, they are used for various tasks such as tightening bolts in the engine, alternator, exhaust system or suspension components and are also used to work on brake components or remove and tighten lug nuts when changing tires.
• This tool is useful for working with fuel, oil or cooling system lines where you need to access fasteners in tight or awkward spaces.

Crowfoot Wrench

Crowfoot wrenches are specialized hand tools that are used primarily for tightening or loosening fasteners in hard-to-reach areas where a standard spanner or wrench cannot generally fit. They consist of open-ended designs that are typically used with a ratchet or extension bar. It is important to note that most DIY users generally don’t have this particular wrench in their arsenal however, believe us when we say that having this particular wrench in your tool kit is quite essential. Crow’s foot wrenches are available in various sizes and can be used for both metric and standard fasteners.

Common Uses of a Crow Foot Wrench:

• It is ideal for use in tight spaces, such as those that are behind engines or under vehicle dashboards.
• Their ability to be utilized at various angles, allows them to provide a better leverage and access to fasteners.
• This tool allows for the application of torque without obstructing adjacent components.
• Some of the scenarios where they are often utilized include uses during automotive repair, plumbing and HVAC work.

Stubby Wrench

Just by reading its name, most of you who haven’t heard of this particular wrench can already guess what this hand tool looks like. These hand tools have standard wrench ends on either point, however, the handle connecting them is way shorter than what you normally find on other wrenches, so much so that they can fit inside the palm of your hand, making them extremely versatile and perfect for reaching hard- to- reach fasteners.

Common Uses of a Stubby Wrench:

• They are commonly used for tasks in tight, cramped areas where a standard-length wrench cannot fit. This includes working around obstacles like pipes, beams or other equipment.
• When assembling furniture, especially in cramped areas (like inside cabinets or around walls), it helps tighten or loosen bolts and nuts that need only a moderate amount of torque.
• They are often used in bicycle repair, especially for adjusting parts like pedals, brakes and handlebars, where fasteners are usually present in cramped or awkward positions.

Ring Spanner

A ring spanner, which is also known as a box-end wrench, is a type of tool designed to grip and turn fasteners (such as nuts and bolts) using a fully enclosed, circular opening. Unlike an open-end wrench that only has two sides gripping the fastener, a ring spanner encircles the fastener completely, providing better grip and minimizing the risk of slippage. These spanners are double ended with offset handles that vastly help improve access to the nut or bolt. Their openings have hexagonal recesses that enable them to properly fit on the nuts.

Common Uses of a Ring Spanner:

• These spanners are useful for working with bolts on wheels whilst removing or installing lug nuts or other wheel-related fasteners.
• Their box-end design is ideal for working on transmission parts where a secure grip is essential to prevent slippage or damage to their fasteners.
• In construction, ring spanners are used to tighten bolts in structural steelwork, machinery and in large equipment that require secure and high-torque connections.
• They are used in assembling or disassembling heavy machinery, where precise torque is needed to avoid damaging bolts or nuts.
