A tolerance class is made up of two parts, a tolerance grade, and a tolerance position. In Fusion 360, the class represents the tolerance class, or how much variance is allowed. The 6g is the tolerance class for the major diameter. The 5g indicated the tolerance class for the pitch diameter. The designation for a metric thread includes information on the thread diameter, pitch, and thread tolerance class.įor example, a thread designated as m12x1 – 5g6g indicated the thread has a nominal diameter of 12mm and a pitch of 1mm. Major Diameter – the diameter determined by the thread tips.Minor Diameter – the diameter determined by the groove of the thread.Pitch Diameter – the distance of two opposite flanks or the distance of the centerline of the profile.Thread Flank – the straight sides that connect the crest and the root.Thread Angle – the angle between the flank of a screw thread and the perpendicular to the axis of the screw.Pitch – the distance from the crest of one thread to the next (typically measured in mm).Crest – the outer-most part of the thread.Root – the inner-most part of the thread.Typically used for general-purpose screws. ISO Metric Profile – one of the most common thread types worldwide.BSP Pipe Threads – standard thread type that has been adopted internationally, and used all throughout Europe, for interconnecting and sealing pipe ends.ACME Screw Threads – most commonly used as lead screws because of their trapezoidal thread shape.All of the thread types are based on industry and global standards that are produced for different product needs. Thread Types in Fusion 360įusion 360’s Thread feature offers several preset thread types. These threads can be 3D Printed, milled, or used in 2D manufacturing drawings. Fusion 360 has a thread feature that lets users easily recreate realistic and working threads for their projects.
