scrubber system—see figure-47 5
1. On very large jackbolts when the torque required for a specific preload would be too high; or,
2. Where space restrictions prohibit the use of sufficiently large torque wrenches.
In some cases, SUPERBOLT tensioners are “broken in” at the factory to lower the friction factor for field installation.
Fel-Pro C-870 molybdenum-disulfide paste has performed similarly to JL-M. Other molybdenum pastes and greases tested had much high friction factors. Testing for friction factor is recommended for all critical installations where lubricant and/or bolt and nut materials are unknown.
