NELSON STUD WELDING SPECIFICATION: CFL Fully Threaded Studs

CFL

Nelson CFL studs are recommended for fastening applications where threads are needed for the full fastener length. CFL studs a re available in thread diameters of 1/4"-20 through 1”-8. Nelson fully threaded studs have a short length of pitch diameter weld base. Most of this length is melted off during the stud welding process so that usable thread extends down to the top of the weld flash on installed studs. For similar function studs, see CFP Small Diameter Threaded studs, CJL Reduced Base studs, L Partially Threaded studs, HBA Aluminum Full Base Diameter Threaded studs, HBL Full Base Diameter Threaded studs, Banding Cable Hangers, CrimpLok™ Cable Hangers, and Watertight nuts.

When ordering, specify Type, Diameter, Before Weld Length, Material, Quantity, and Part Number Example: CFL 3/8-16 x 2-1/4”; Mild Steel; 10,000 pieces; #101017193 Thread Minimum Burn Weld Base Weld Base Stud Diameter Length Size Off Length C A

Stud lengths shorter than those shown above can be supplied in sizes 1/4"-20 through 1/2"-13 by using special low profile ceramic ferrules. All low profile ferrules, except the 1/4”-20 ferrule, were designed for use with full diameter weld base studs. For this reason, the weld flash size and flash clearance are increased. The minimum length, weld flash clearance, recommended deviance, ferrules, and ferrule grip numbers are shown below. Thread Size
