Each of these UJK hold-downs comes complete with an M8 x 50mm tee-bolt and an M8 through-threaded star knob. The tee-bolt is compatible with the UJK T-Track allowing you to use these hold-downs in a variety of situations. Also features an aluminium stepped track adaptor for use in T- tracks.
Obviously, by substituting the tee-bolt for a regular M8 bolt you have the option of taking advantage of the hold-down on a bench top or anywhere else.
The reach is 50mm, with non-marring tips to prevent slipping and any potential damage to a workpiece.
