Gagemaker has been an industry recognized name when it comes to gages required by API for inspecting threaded tubular goods for over 20 years. Our gages cover two critical inspection areas: diameter measurement and thread element inspection. Our wide range of products suit most API inspection needs and meet API Specification 5B and Specification 7 requirements. The patented MRP gages inspect pitch and functional diameters of tapered threaded connectors. Each MRP gage is adjustable within a size range. This feature not only provides flexibility, but it also allows one gage to measure a wide range of diameters. Our line of thread element inspection gages includes: lead, taper, thread height, and profile gages, just to name a few. The superior performance of these gages, provides reliable and accurate results when inspecting tubular connectors. We also specialize in inspection gages for premium thread designs. Many of our premium connection gages have been adopted as the industry standard by proprietary threaders.
