The terms spanner and wrench are often interchangeable and can cause some confusion when searching for the right tool. In the USA, wrench is the name used for a spanner, and because the USA and European markets are connected, the term often filters through. In the UK, a wrench is similar to a spanner, but instead of turning fasteners like nuts or bolts, it turns and manipulates non-fastening components, like pipes. If two people (Person A and Person B) sit on a seesaw, the moment of each person equals their weight multiplied by their distance from the pivot.

We want to make it easy for you, so here are some key terms that will help you understand the range and applications a little better Let's increase the length of the spanner to 20 centimetres, keeping the force used at the end of the spanner at 25 Newtons. We work this out by multiplying the distance from the pivot to the point on the spanner where the force is applied in metres by the force on the spanner. Length - This affects the amount of torque generated to turn the fixing. More power will be generated by a long spanner for larger or stubborn fixings.General-purpose applications often utilise open-ended or combination spanners, where a six- or twelve-point profile is common to give adequate grip. For this type of activity, spanner sets are ideal and are comprised of a handy range of sizes to suit the most common sized fittings. If we apply a 25 Newton force to the end of the 10-centimetre-long spanner to turn a nut, what is the moment?

The first step in choosing a spanner for the job is to find out the head size on the fixing. These are usually marked on the fixing, but if this has been worn away, you can still identify it by measuring the width across the flat angles of the bolt head. This is the widest side of the fixing and shouldn't be confused with the shorter side.

One of the most well-used hand tools by professional tradesmen and DIY enthusiasts alike, the spanner is extremely useful in a wide range of industries. Made from durable materials like vanadium steel or titanium, these resilient tools are often plated to protect against corrosion and general wear and tear. This standard refers to open-ended, box and combination spanners. It outlines the maximum head dimensions for these tools.

Spanners are incredibly versatile, cost-effective and easy to use. They are also a crucial element in performing many jobs. Moments are measured in Newton metres and the size of a moment depends on two factors: the size of the force applied and theA seesaw is a balanced system of moments where two people are balanced on a solid object on top of a fulcrum or pivot. ISO - The International Organisation for Standardisation defines global safety and quality standards Used widely in plumbing, automotive and construction work, spanners are an essential tool when safely and reliably connecting components with a rotary fastener, like a nut or bolt. Specialist application spanners include basin-tap and box spanners, which are used widely by plumbers and engineers to reach into tight spaces. Material - The stronger the material, the stronger the tool. Good quality spanners are mostly made from vanadium steel or titanium.
