About Feeler, Radius & Thread Gauges
A feeler gauge consists of several thin blades for measuring narrow gaps or clearances, mostly in engineering to measure the clearance between two parts.
A radius gauge, also known as a fillet gauge, is a tool used to measure the radius of an object. It is a hand-held tool with many precision rounded curves (radii) machined into its edges.
A thread gauge checks the dimensions of a specific thread form angle, pitch, and diameter. They are a reference tool in determining the pitch of a thread on a screw or in a tapped hole.
