Introduction

GB/T 5796 "Trapezoid Thread" consists of 4 parts. --- Part 1.Tooth shape. It establishes the basic dimension formula of thread diameter for part 3 and part 4 and determines the start of thread tolerance zone Location provides the technical foundation. --- Part 2.Diameter and pitch series. It establishes the basic dimension table of thread diameter and determines the thread diameter for part 3 and part 4 The difference table provides a specification basis for nominal diameter and pitch. --- Part 3.Basic dimensions. It provides a technical basis for determining the limit size of the thread diameter. --- Part 4.Tolerances. It provides technical basis for product production and inspection. The four parts of tooth type, diameter and pitch series, basic dimensions and tolerances constitute the complete technical parameter system of "Trapezoid Thread". put them together It is convenient for users to find and use within a standard. Trapezoidal threads part 3.basic dimensions
