Introducing the RS PRO brass feeler gauge, a compact hand tool ideal for measuring gap sizes between mechanical parts and materials. This feeler gauge features 13 blades with 0.05mm increments printed onto the blades, allowing for quick and easy measurement. The blades are manufactured from brass offering a highly durable and corrosion resistance gauge, ideal for use in a wide range of environments that require non-magnetic tools. The blades are also housed in a durable brass case with thumbscrew, allowing you to loosen or tighten the blades and select the desired one whilst keeping the remaining blades safely stored.

Feeler gauges are a type of measurement tool used to measure the clearance between two parts or pieces of material with precision. They feature several blades (or leaves) that vary in thickness. Feeler gauges are used in a wide range of applications including:

• Engineering


• Carpentry


• DIY


• Automotive


• Industrial

DIN 2275

Brass feeler gauges are designed to be used with components that require non-ferrous and non-magnetic tools to operate, such as early electronic ignition systems.

The RS PRO feeler gauge features metric measurements in mm (millimetres).

This feeler gauge features 13 blades with thickness sizes 0.5 to 1mm.

Can be used for checking a range of materials and parts including: tappet clearances, spark plug gaps, distributor points, bearing clearances and piston ring gaps.
