Hold and tighten right-hand threaded studs and rods without damaging threads. Unlike pliers or locking grips, these drivers screw onto the stud for a secure, nonmarring hold. They unscrew easily for quick release. A cushioned handle provides comfort and slip resistance. Grip the _5/8" hex end with a wrench for more torque. Made entirely of stainless steel, they resist corrosion in wet and washdown environments.
