fine polishing Hydraulic Nuts alunimun For Steel Coil Slitter machine
Do bolts stretch when torqued?
As you tighten a bolt, it will stretch and generate a clamp load. The key to proper tightening of a fastener is to torque it until just slightly less than the bolt's elastic limit. A bolt will stretch slightly as it is tightened. If you tighten the bolt too much, it will stretch beyond its elastic limit.

What happens if you reuse a torque to yield bolt?
These bolts cannot and should not be reused due to the stress caused to the bolt during its first installation. It is important to be aware that these bolts will not have the same clamping strength if attempted to be used a second time. Torque-to-yield bolts may break if reused or become loose over time.
A hydraulic bolt tensioning tool provides a quick and easy method for tightening large diameter bolts to high and accurate pre-loads. Unlike conventional methods it does not use torque and does not require any forceful turning of the nut or bolt, like impact wrenches, flogging spanners or hydraulic torque wrenches.
Senda can provide full sets of slitter line tools,such as slitter knife, rubber bonded rings, spacers, separator discs, hydraulic nuts and etc.
