18 | 2.0 | Blue Loctite 242 | Any removable type | Hand feel is OK for the jam nut torque. The jam nut is used to lock the screw in place. Threadlocking compound is helpful but not critical. If no nut is used, we recommended to apply threadlocking compound for nearly every adjustment. |

2.5mm hex | N/A | N/A | Vibra-Tite VC-3 | Removable type with rubber-like hardness | Ideally, this should be soft and re-usable so limit screws do not move during use. If using an alternate threadlocking compound, apply with nearly every adjustment. |

8 | 0.9 | Red Loctite 277 or 263 | Any high strength type | Threads must be cleaned with degreaser followed by isopropyl alcohol after installing the bushings with grease. The metal locknut should not be worn out. Do not use a nut with a plastic insert - it will loosen. The goal is to create a rigid bond that will not loosen. Higher torque is not better for this fastener. |
