Nelson Fastener Systems Reinforcing Standoff Support Stud B4L / B4P

Nelson’s B4L and B4P studs have a 90 bend and are used for exposed hangars and steps. They are also embedded as anchors or supports for positioning reinforcing bars. The basic stud may be an unthreaded NBL or a deformed bar anchor, D2L. The stud burn off and weld flash information for these studs is the same diameter as NBL no thread type studs. These Studs are usually welded using a ferrule footplate or split feet. Grips may be used if the weld leg length, “L”, is long enough. Special chucks are required to hold these studs into the stud welding gun.
