B5L 3/8 X 2 5/8 MS 1 1/2 EXT SPEC - 102006029

1. Collared studs are made of mild steel or stainless steel. Standard threads are UNC-2A coarse thread prior to any plating, 3” length. Standard metric studs are available with standard thread length of 10, 12, 16, 20, 25, 30 and 35 mm. in ISO 13918 6g series thread. 2. PKL collared paint groove studs feature helical grooves running through the threads axially along the length of the stud. These grooves allow the application of paint without the use of a protective cover, as the bulk of the paint flows down the grooves and does not become trapped in the threads. Subsequent installation of nuts is permitted where a stand-off is required. 3. B5L feature a 90 degree bent. The thread extension speeds assembly over installing a bolt into an internal threaded boss or tapped stud.
