Stud Installation
1. Mark the stud pattern on the track.
2. Drill stud holes with a 1/4s (7mm) hollow-core drill bit. Make sure the drill is sharp for a clean hole.
3. Spin the non-cutting portion of the drill shank in the hole at high speed to melt the cords together, or melt them
with a 1/4-9/32s heated probe. This will prolong track life.
T-nut Studs
1. Push a T-nut tool through the hole from the outside of the track.
2. With the barrel end of the T-nut toward the track, spin a T-nut onto the tool. Pull the T-nut into the track until the
head is flush with the track.
3. Remove the tool and put a drop of Loctite¥ 262 or 271 on the nut threads and stud threads.
4. Secure the T-nut, slide a support washer onto the stud, and screw the stud into the T-nut
5. Torque to 80-100 in. lbs. and let dry for 24 hours at room temperature.
6. Check for loose studs after each event.
Push Through Studs
1. Push stud through track hole from inside track. Hand tighten domed support plate and Nyloc nut on the
exposed stud.
2. Tighten with a socket on the nut and a 5.32s allen wrench on the stud head. Tighten nut until the domed
washer bottoms out on the stud shoulder. If tightened beyond this point, the threads will be stripped.
3. Inspect for loose nuts after each event.
