System Overview
Improper operation may lead to deadlock of Nuts and Bolts. The steps below should be applied to
every stainless steel nut and bolt assembly to reduce this risk.
4.2 Precautions during Stainless Steel Fastener Installation
4.2.1 Reduce the friction coefficient:
(1) Ensure that the thread surface is clean (no dirt or contaminant)
(2) Apply lubricant (grease or 40# engine oil) to fasteners prior to tightening to avoid galling or seizing of
threads;
4.2.2 General installation instructions:
(1) Apply force to fasteners in the direction of thread
(2) Apply force uniformly, to maintain the required torque
(3) Professional tools and tool belts are recommended
(4) Avoid using electric tools for final tightening
(5) Avoid working at high temperatures
4.2.3 Safe Torques
Please refer to safe torques defined in this guide as shown in the figures below. When fixing mid and end
clamps, if the torques range specified by the panel manfuacturer is different, it should be used instead. In case
power tools are required, Clenergy recommends the use of low speed only. High speed and impact drivers
increase the risk of bolt galling (deadlock) If deadlock occurs and you need to cut fasteners, ensure that there is
no load on the fastener before you cut it. Avoid damaging the anodized or galvanized surfaces.
