Nelson 101-010-122-G100 Weld Stud CFL, 3/8"-16 x 1 1/2", Steel, 100 PK

These drawn arc weld studs are fully threaded along their entire length when installed on a workpiece. A short base section is melted off during the welding process. The studs form strong, vibration-resistant welds that provide a tight seal against water, oil, air, or gas leaks at the weld point.
