Pin gauges are cylindrical rods of specific dimensions, manufactured from high-hardness materials such as white steel, tool steel, ceramic and tungsten steel. They are suitable for measuring bore diameters, hole spacing and the small diameters of internal threads in mechanical and electronic machining, and are particularly suitable for measuring the width of bent grooves and mould dimensions. Pin gauges can be used to verify positioning, measure hole dimensions, and check the distance between two holes. They can also serve as go/no-go gauges and tools for measuring hole depth. As an indispensable tool for standardised hole inspection, they feature internationally advanced laser detection capabilities for inspecting workpieces. They are widely used in various high-precision technologies across fields such as electronic boards, circuit boards, moulds, and precision machinery manufacturing.
Precautions before use
Before use, clean the gauge with petrol or wipe off rust-preventive oil and dirt with a clean cloth. Ensure there are no traces of rust, scratches or burrs.
Precautions during use
When using a pin gauge, ensure the end face is free from burrs or rust. Be mindful of temperature differences in the workpiece. For straight pin gauges, use a pin holder or gloves, and be aware of the effect of temperature on the gauge’s dimensions.
Post-use precautions
After use, clean the gauge and apply oil. Ensure there are no scratches, then store it in the supplied case. For long-term storage, have the gauge inspected every six months, apply rust-preventative oil, and store it in a location with minimal fluctuations in humidity and temperature.
