 The
BlackJack® Stud Runner or stud extractor is a versatile tool designed for the
removal or insertion of threaded studs into blind stud holes. Stud
runners are made for stud diameters from 1/2" to 7" with
any thread pitch available. Clamping force on the end of the stud
is generated by a closing collet designed to grip the minor diameter
of the thread without inflicting damage on the thread root.
A knurled collet is used for superior clamping on the stud when replacement studs will be utilized.

The
principal operation entails threading the collet on to the stud
until it is bottomed out. A multi-jack bolt tensioner is tightened
with an allen key forcing the tapered ring down over the collet.
The taper produces an internal radial clamping force that compresses
the collet onto the stud. The Stud Runner grips so tightly that
a tremendous amount of torque can be applied in either direction.
The collet design provides a 1/2"; 3/4"; 1"; 1-1/2"
or 2-1/2" female square drive for use with standard tooling,
such as impact wrenches, hydraulic torque wrenches or breaker
bars when removing or installing a stud.
