Shear strength of bolts. The shear resistance of the bolt per shear plane F v,Rd is provided in EN1993-1-8 Table 3.4: F v,Rd = α v ⋅ f ub ⋅ A / γ M2. where: α v is a coefficient that takes values α v = 0.6 for bolt classes 4.6, 5.6, 8.8 or α v = 0.5 for bolt classes 4.8, 5.8, 6.8 and 10.9.
Metric bolt grades and strength calculator to show proof strength, tensile strength, Vickers / Brinell hardness, minimum breaking torque and stress area of metric bolts and screws made of carbon steel and alloy steel with designations 4.6, 4.8, 5.8, 8.8, 9.8, 10.9 and 12.9.
Minimum ultimate tensile and proof loads for metric bolts with coarse or fine threads. Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications!
As a layman, how can I know the shear strength of a particular size bolt? For example, if I want to attach something to the internal wall of my van ( 1mm stainless steel ) using a rivnut and standard metric bolt and it should hold up to 50 kg, how would I figure out the right size and grade to use?

Tensile Strength: The maximum load in tension (pulling apart) which a material can withstand before breaking or fracturing. Yield Strength: The maximum load at which a material exhibits a specific permanent deformation.
Shank (1) €shear capacity of the unthreaded section (plain shank) of the fastner. Thread (2) €shear capacity of the threaded section of the fastener. Notes – all shear capacity values are given in kilo-Newtons (kN) – all values represent the minimum breaking load in ‘single’ shear. Bolt Shear Capacity€Metric* Class 4.6 Class 8.8 ...
