This stud has a long history of success in Woody s line. Alarger carbide wedge is brazed into a steel body for deep penetration. Position the wedge in line with sled travel and the stud will aid in cornering control. Rotate the wedge 90° and the stud hooks up for starting and stopping traction. Or use a combination of positions in your track. Available in regular T-nut style or simplified Snap-Off™ studs. With the Snap-Off™ studs there is no need for a T-nut puller because of the extra long thread to start the T-nut. Once the stud is tight and the T-nut is flush to the track just snap off the excess thread
