Product Information

Since the system is balanced, we can calculate an object's weight measured as a downward force in Newtons, or distance from the pivot. 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.

Material - The stronger the material, the stronger the tool. Good quality spanners are mostly made from vanadium steel or titanium. Specialist application spanners include basin-tap and box spanners, which are used widely by plumbers and engineers to reach into tight spaces. Spanners are incredibly versatile, cost-effective and easy to use. They are also a crucial element in performing many jobs. A moment is the turning effect of a force around a fixed point, the pivot. Examples include a door opening around a fixed hinge, seesaws, scissors or a spanner turning around a nut.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. 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. 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.

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. 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.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 If we apply a 25 Newton force to the end of the 10-centimetre-long spanner to turn a nut, what is the moment? Moments are measured in Newton metres and the size of a moment depends on two factors: the size of the force applied and the ISO - The International Organisation for Standardisation defines global safety and quality standards

This standard refers to open-ended, box and combination spanners. It outlines the maximum head dimensions for these tools. 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. A seesaw is a balanced system of moments where two people are balanced on a solid object on top of a fulcrum or pivot.So, the moment of Person A, their weight multiplied by their distance from the pivot equals the moment of Person B, their weight multiplied by their distance from the pivot. 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.
