Hexagon bolt calculation and drawing

Hexagon bolts are a very common type of bolt and are used in a wide range of applications. The connected parts can be fastened by bolts, nuts, and washers. The function of the ring is to prevent the surface of the connected parts from being damaged when the nut is tightened, and the pressure of the nut is evenly distributed to the surface of the part. The connected parts are machined to have unthreaded through holes. The diameter of the through hole is slightly larger than the thread diameter. The exact size can be checked. When drawing a bolt connection, the nominal length l of the bolt must first be calculated. The bolt length l≈k+m+g1+g2+b1 is calculated after the length is calculated and the standard length l is taken according to the bolt length series. The following figure shows the bolted assembly drawing. The size of bolted joints can be obtained from standard checklists. However, approximate dimensions can be used when drawing threaded fasteners. Where: b1≈0.3d; m≈0.8d; k≈0.7d; e≈2d; d2≈2.2d; c≈0.15dx45; h≈0.15d; e≈2d. More products /news/314.html
