Plain Plug Gages

Plain plug gages check the size of a hole — GO/NO GO, no threads — and are the workhorse of dimensional inspection. WESTport builds every mounting style and material so the gage matches the tolerance, wear, and handling the job demands.

• Taperlock and Trilock mounts for standard and larger diameters.
• Reversible gages — two members in one handle.
• Progressive gages combining GO and NO GO on a single member.
• Steel, hard chrome, and carbide for wear resistance where it counts.

Class XX, X, Y, Z, and ZZ tolerances, to ANSI/ASME B89.1.5, certified in our ISO/IEC 17025 laboratory.
