The standarized properties of metric bolts are specified in the international standard.The course pitch thread bolts are used for general applications.The letter 'M' is used to designate them by their nominal diameter.M3 is the standard course pitch thread metric bolt size.For special applications fine pitch thread bolts can be used.They are also included in the pitch of thread.M8 1, M14 1.5, M27 2 etc.The stress area of fine pitch thread bolts passing through the threaded part is larger than the course pitches.For fine pitch thread bolts, the strength properties may be used conservatively.
As part of the bolt designation, the nominal diameter d is specified in millimetres.M8 bolt has 8mm.The standard metric bolt diameter is specified in the ISO 898-1 Tables 4 and 5.The standard sizes for coarse pitch thread bolts are M3, M 3.5, M4, M5, M6, M7, M8, M10, M12, M14 and M16.
The bolt sizes M5 to M39 are specified in ISO 898-2 Table A.1 for the width of the hexagon nuts.
The design shear resistance of bolts Fv,Rd is only valid when the bolt is used in holes with nominal clearance not exceeding the values given in the standard EN1090-2 'Requirements for the execution of steel structures'.The hole diameter d0 is determined by adding the nominal clearance of the bolt to the hole's nominal diameter.
The cross-sectional area of the bolt is equal to the nominal gross area Ag.
The reduced cross-sectional area is found inside the threaded part of the bolt.The thread can be used to calculate the stress area.The nominal stress area is provided in ISO 898-1 Tables 4 to 7.
The shear stress area and the tensile stress areas are not the same.The shear strength of the bolt may be determined by the stress area.
The ultimate tensile strength fub for bolt classes is given in Table 3.1.The ultimate strength is determined by the first number of the bolt class.For classes 4.x, 500, 600, 800, and 1000MPa are available.The yield strength to ultimate strength ratio is related to the second number.Class 4.6 has a yield strength of 0.60 400 MPa.
The values of k2 are 0.63 for countersunk bolts or 0.9 otherwise.The ultimate strength of the bolt is called fub.The bolt's nominal stress area is the same.The National Annex states that M2 is the partial safety factor for the resistance of bolts.M2 is the recommended value.
The values of v are used to calculate the coefficients for bolt classes 4.8, 5.8, 6.8 and 10.9.When the shear plane passes through the unthreaded part, fub is the ultimate strength of the bolt.The tensile stress area of the bolt As is equal to the shear plane's travel through the threaded part.The gross cross-sectional area of the bolt Ag is equal to the shear plane passing through it.The National Annex states that M2 is the partial safety factor for the resistance of bolts.M2 is the recommended value.
The relationship between shear and tension is expressed in Table 3.4.
The shear load is applied and the shear resistance is the bolt.The tension resistance of the bolt is called Ft,Rd.
The bearing resistance of the bolt should be verified against the applied shear load.
The nominal diameter of the bolt is what determines the ultimate tensile strength.The thickness of the connected plate is t.The National Annex states that M2 is the partial safety factor for the resistance of bolts.M2 is the recommended value.
k1 is the min for edge bolts and inner bolts.
The distance between the edge bolt and the end of the plate is measured by the load transfer direction.
The diameter of the bolt hole and the distance between the centers of neighboring bolts are measured parallel to the load direction.
When the following conditions are satisfied, the bearing resistance of the bolt is not affected by the distances e1, p1, e2, p2
For edge bolts, e1 and e2 are 3.0 and 1.5d0, respectively.
The punching resistance of the bolt should be verified against the applied load.
