The range of a screw pitch gauge is about ________.

Explanation:

Screw pitch gauge:

• A screw pitch gauge is used to determine the pitch of a thread.
• It is also used to compare the profile of threads.
• Pitch gauges are available with a number of blades assembled as a set.
• Each blade is meant for checking a particular standard thread pitch.
• The blades are made of thin spring steel sheets and are hardened.
• Some screw pitch gauge sets will have blades provided for checking British Standard threads (BSW, BSF, etc.) at one end and the metric standard at the other end.
• The thread profile on each blade is cut for about 25 mm to 30 mm.
• The pitch of the blade is stamped on each blade.
• The range of a screw pitch gauge is about 0.35 mm to 5.0 mm.
• The standard and range of the pitches are marked on the case.
