DIN 976 Stainless Steel SS304 SS316 M2-M72 Fully Threaded Rod

Description:

Threaded Rod, also known as the screw. Han Ming and Qing era furniture components name. GB Base standard corresponding to DIN975. Due to different locations and names are different. Generally refers to the setting member is connected between the legs of the lower surface of the frame. There corset waist furniture in the following parts of the main coupling member. Located in other parts of the general renamed teeth. In addition, also used in the construction, most decoration.

For threaded rod that are not completely threaded, there are two types of studs: full-bodied studs, and undercut studs Full-bodied studs have a shank equal to the major diameter of the thread Undercut studs have a shank equal to the pitch diameter.. of the screw thread. Undercut studs are designed to better distribute axial stresses. in a full-bodied stud the stresses are greater in the threads than in the shank.

Undercut studs (rolled thread) are also stronger because the metal is "rolled" up to the major diameter, not removed. This preserves the grain of the steel, and in some cases even enhances it. Full bodied studs (cut thread) are weaker because metal is removed to create the thread, disturbing the grain of the steel.

Undercut studs are only required in applications where the stud is exposed to fatigue. Cut threads are entirely suitable for many applications, even when rolled threads might be slightly stronger. Mass-produced fasteners (standard bolts and studs) are usually rolled, but jobbed parts with custom features and small lot sizes are likely to be cut.
