The bolts used in the boss interlocking clamps are not standard bolts
They vary from standard bolts in their lengths, diameter, overall thread lengths and materials hardness
These bolts can be retorqued, but it is not recommended to reuse the bolts or clamps, as they are designed for a single bend only
Torque values for clamps are based on dry bolts
The use of lubricant on bolts will adversely effect clamps performance
Do not lubricate nuts and bolts
Bolts in boss clamps are designed to bend as they are tightened and this allows the clamps to conform to the hose outside diameter
Always tighten bolts to their specified torque values
Periodic re-tightening of bolts is required due to "cold flow" phenomenon present in all rubber hoses
Boss clamps are for single use only, once removed they are to be discarded
