Ensure flawless quality control with our professional technical documentation for the Hole Measuring Pin. Also known as a “Plug Gage” or “Pin Gage,” this essential metrology tool is the primary standard for verifying hole diameters, distances between centers, and bore depths. In high-precision industries like aerospace and medical device manufacturing, even a micron-level deviation can lead to assembly failure. This drawing package provides the exact geometric specifications and material requirements needed to manufacture or calibrate high-tolerance measuring pins that meet international inspection standards.+1

The provided الرسم package offers a detailed look at the cylindrical grinding tolerances and the surface finish requirements (typically measured in Ra) necessary to prevent friction-based wear during inspection. By analyzing the chamfered lead-in design and the ergonomic handle interfaces in these blueprints, engineers can develop custom gauging solutions for unique bore sizes. We offer these high-fidelity CAD resources for free to help quality assurance teams maintain the highest levels of accuracy in their measurement workflows.

Our files are compatible with all major engineering platforms, allowing you to integrate these pin models into your virtual assembly checks to verify fitment classes (such as H7/g6) before physical production. Utilizing these professional schematics ensures that your pins are manufactured with the necessary hardness to resist deformation over thousands of inspection cycles. Download this essential resource today to standardize your measurement procedures and reduce the risk of non-conforming parts.
