{"product_id":"serration-spline-plug-gage","title":"Serration Spline Plug Gage","description":"\u003cp\u003eWESTport serration plug gages inspect \u003cstrong\u003einternal serrations\u003c\/strong\u003e — the multiple equally spaced teeth that give positive engagement between mating components. The GO member confirms the serrated bore will assemble with its mating part; the NO GO member guards the upper dimensional limit. Both together give a fast functional check without measuring every tooth.\u003c\/p\u003e\n\u003ch2\u003eSerration or spline?\u003c\/h2\u003e\n\u003cp\u003eSerrations and splines are different tooth forms and each needs its own gage.
