Design Code, BS5950       Steel Plate Yield Strength, 275 265 275 355   N/mm2    

Quality of cut, rolled, machine flame cut, sawn or planed edge or end sheared or hand flame cut edge or end         Bolt grade, 8.8 4.6 8.8 10.9      

Or use U_b : minimum tensile strength of the bolt and Y_b : specified minimum yield strength of the bolt,
U_b = N/mm² (U_b ≤ 1000 N/mm² )     ( Note : if this is > 0 , bolt grade will be ignored)
Y_b = N/mm² (Y_b < 0.7 * U_b )    

Bolt Size, 16 10 12 16 20 22 24 25 28 30 35 40   mm    

Opening type, bolts in standard cleanance hole : kbs = 1.0 bolts in oversize holes : kbs = 0.7 bolts in short slotted holes : kbs = 0.7 bolts in long slotted holes : kbs = 0.5 bolts in kidney-shaped slots : kbs = 0.5   mm    

Ultimate Tension, T_ult = kN     Ultimate Shear, V_ult = kN
