Should you reduce the recommended torque on a fastener when using Locktite?
No. The recommended torque has more to do with how much force the fastener exerts than preventing it from coming out.
What rockwell c hardness is grade 10.9?
The Rockwell C Hardness for a grade 10.9 fastener is 32 - 39HRC or 320 - 380Hv10
Difference between 10.9 and 12.9 tensile bolts?
Grade 10.9 bolts or capscrews have a minimum tensile strength of 1040N/mm2 and a hardness of 320 - 380Hv10. Grade 12.9 bolts or capscrews have a minimum tensile strength of 1220N/mm2 and a hardness of 385 - 435Hv10. The 12.9 fastener is therefore a higher grade (hardness and tensile strength) fastener compared with 10.9 grade
What is mean by reverse torque testing?
Once the initial torque is applied to the fastener, a reverse torque test can be performed to make sure that the fastener has not loosened due to vibration or other conditions like material fatigue or yielding. So, lets say you tighten a bolt to 150inlb with a torque wrench. You should be able to take that torque wrench and apply 150inlb to the bolt in the reverse direction without the bolt loosening (reverse torque is gretaer in almost all cases, depending on materials because initial static friction must be overcome.)
What is the disadvantage of threaded fasteners?
Well, most of the threaded fasteners used in general applications have the following disadvantages: 1. Continued exposure to vibration tends to loosen the fastener. 2. If the fasteners are not creep resistant, they will fail at elevated temperatures. 3. The sharp edges formed in the threads of the members acts as stress concentration regions and is undesirable. This is to some extent overcome by introducing a small radius at the crests and troughs of the threads.
