Self clinching studs are used to provide a male thread on a sheet material without welding.
Self clinching studs are installed by drilling an appropriately sized hole in the sheet material, inserting the stud and then compressing it into place using a press. The underside of the stud has teeth that, under the pressure of the press, sink into the sheet metal and grip it. This grip then provides resistance against any rotational forces when a female thread is connected on to the stud.
Self clinching studs have a flush head and are available in zinc plated or stainless finishes.
About The A2 Stainless Steel Finish
A2 stainless steel is often referred to as 304 or 18/8 Stainless. 18/8 actually refers to the amount of chromium and nickel in the alloy - 18% chromium and 8% nickel.
A2 stainless is the most common type of steel used for the manufacture of fasteners and is suitable for general use.
