I am going to be drilling into hard granite and was wondering what length of bolt is considered safe. I saw a lot of different answers all over the internet. I will be using Fixe Wedge Bolts (I ordered a drill package), and they give you 4 3/8 x 3 1/2 bolts and 6 3/8 x 2 1/4 bolts The bolt length is usually short, 2-3 m, in this type of rockbolting. The thickness of the interaction zone is required to be at least 0.5L b in order that a strong enough artificial arch can be established in the broken rock. This requirement leads to a bolt spacing that should be less than half of the bolt length, i.e. (7) s ≤ L b /

To optimise a bolted joint, it is recommended to design the clamped length to at least 3 or 5 times the bolt diameter. Increasing the elasticity of the fastener greatly improves the properties of the joint, as it: Increases the elongation of the bolt, reducing settlement effect. Increases the flexibility of the fastener, reducing the risk of. As far as I know there are no regulations on sizes, but on the loads that need to be supported by said plates and bolts. A diagram of your intended setup and some sizes could be useful. I tried to find design regulations/codes that specify relations between bolt diameter/bolt length against connected plate thicknesses ASTM A325 Bolt Strength.
