3.3 Precautions during Stainless Steel Fastener Installation
Improper operation may lead to deadlock of Bolts and Nut. Follow the steps below to
reduce this risk
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 tightening to avoid
galling or seizing in the threads;
2．General installation instructions:
（1）Apply force to fasteners in the direction of thread;
（2）Apply force uniformly, to maintain required torque;
（3）Professional tools and tool belts are recommended;
（4）Avoid using electric tools for final tightening;
（5）Avoid working at high temperatures;
3．Safe Torques
Please refer to safe torques defined in this guide as shown in below; 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 please make sure that there is no load on the fastener before you
cut it. Avoid damaging the anodized or galvanized surfaces.
M8 Nuts：18-20N·m
M8*35 bolts：10-12N·m
M8 Nuts：8-9N·m
M8*25 bolts：18-20N·m
U bolts M8*58：8-9N·m
M6*14 bolts：8-9N·m
