Threaded studs are available in 1/4"-20 and 3/8"-16 thread diameters with a variety of thread and shank lengths for use in concrete, some types of masonry, and A36 structural steel. They are used for applications where it may be desirable to remove the fixture, where shimming may be required. The shank diameter for the threaded stud is 0.145" for the 1/4"-20 diameter and 0.205" for the 3/8"-16 diameter. Knurled shank designs are available to increase performance in steel base materials. A plastic flute is mounted over the point to retain the drive pin in the fastener guide of the tool providing guidance during the driving operation. On the 1/4"-20 threaded studs, a plastic cap is also provided to protect the threads of the fastener during the driving process.
