Grade 8 bolt proof load
WebFor example, I can't imagine a 1/4" bolt failing at these loads. To test, I just screwed a plain old hex-head 1/4 x 3 1/2 screw into the bottom of my workbench, with about 2 1/2" left visible, and the head holding up a long piece of angle iron. WebThe bolt is stressed up to the proofload value, and if there is no deformation, elongation, or ...

For checking the threads of the aluminum you need to compare the tensile strength of the bolt and the plate. Yes, the hole size matters. It will affect the tensile capacity of the aluminum plate as the available thickness to resist the load is reduced for larger holes. scp containment breach 055WebAnything over a grade 8 fastener (and very rarely a grade 8) Stress above a threshold – There is no clear way to calculate this, unfortunately. Generally speaking a fastener designed to 50% proof will not be high enough. If it is an engineered fastener at 75% of proof of higher, this could lead to an issue.
