Oneway 1 1/2" R/H Jumbo Worm Screw
The ONEWAY Woodworm Screw (Jumbo Screw) design has several unique features which make it a superior wood screw for the turner. These heavy duty screws are made from high tensile steel and are excellent for all types of screw chucking operations.
ONEWAY manufactures a Left Hand Screw for outboard turning that is similar in design to the standard Screw. For large projects longer Right and Left Hand Screws are also available.
They are precision parallel threaded on the body with the first three threads taper threaded which allows:
- easy entry
- minimal damage
- superior holding
A slot is machined around the diameter of the head. This locks in the top jaws which prevents movement of the screw in or out of the chuck.
Four grooves have been milled along the length of the head. When mounting the screw in the chuck, the hardened base jaws inter-lock with the grooves eliminating spinning of the screw.
