This feeler gauge tool from RS PRO comes in handy when you need to measure the width between two objects that are placed very closely together, as its blades can access hard-to-reach spaces. A tool like this is widely used in engineering and mechanical applications. The set consists of 10 blades, which are all attached to a metal casing so they're harder to lose. It's quick and easy to flip separate feelers out of the cover and choose the one that best suits your needs. The blades are made from strong, hardened ground steel, so you can be sure they won't break while you're using them. This metal is corrosion-resistant so won't rust easily. A feeler gauge is commonly found in automotive repair and maintenance tool bags. Typical feeler gauges are used to measure things like spark-plug gaps and piston-ring spacing.
