For standard coarse pitch thread and fine pitch thread bolts the nominal stress area A s is provided in ISO 898-1 Tables 4 to 7. The resulting hole diameter d 0 for each type of hole (normal, oversize, short slotted, long slotted) is determined by adding the nominal clearance given in EN 1090-2 Table 11 to the nominal diameter d of the bolt. Thread lengths listed are a guide value for bolts under 125mm. For bolts longer than 125mm and shorter than 200mm add additional 6mm of thread.

The design shear resistance of bolts F v,Rd as given in EN1993-1-8 Table 3.4 is only valid when the bolt is used in holes with nominal clearance not exceeding the values given in the standard EN 1090-2 'Requirements for the execution of steel structures', as specified in EN1993-1-8 §3.6.1(4).

Definition of standard metric bolts

The tensile stress area A s corresponds to the reduced cross-sectional area inside the threaded part of the bolt. Here’s a short list of standard spanner and allen key sizes that apply to the most commonly used metric nuts and bolts. Standard metric spanner and allen key sizes. Size BS3643 defines the limits and tolerances for ISO screw thread gauges. The standard is divided into two parts. Part 1 is based on ISO 965/1 and ISO 965/3 providing the principles and basic data for specifications of ISO metric screw threads.

class- stamp/meter/account (Including Royal Mail Signed For ® sent as 1st class) Online Postage, Articles for the Blind The standarized properties of metric bolts are specified in the international standard ISO 898-1:2009 'Mechanical properties of fasteners made of carbon steel and alloy steel - Part 1: Bolts, screws and studs with specified property classes - Coarse thread and fine pitch thread'. The following table provides examples of clearance hole sizes, standard or coarse thread pitches along with fine thread pitches and their corresponding tapping hole sizes. Metric clearance and tapping drill hole sizes. SizeThe bearing resistance of the bolt F b,Rd should be verified against the applied shear load F v,Ed in accordance with EN1993-1-8 Table 3.4: where e 2 is the distance between the center of the edge bolt and the end of the plate measured perpendicular to the load transfer direction, p 2 is the distance between the centers of neighboring bolts measured perpendicular to the load transfer direction, and d 0 is the diameter of the bolt hole. The width of the hexagon nuts across flats s is specified in ISO 898-2 Table A.1 for bolt sizes M5 to M39.

Minimum end distance, edge distance, and spacing for bolt fasteners according to EN1993-1-8 Table 3.3 (rounded up to nearest mm) Bulgarian, Croatia, Cyprus, Estonia, Hungary, Latvia, Lithuania, Malta, Romania, Slovakia, Slovenia The yield strength f yb and the ultimate tensile strength f ub for bolt classes 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, and 10.9 are given in EN1993-1-8 Table 3.1. A is the appropriate area for shear resistance. When the shear plane passes through the threaded part of the bolt A is equal to the tensile stress area of the bolt A s. When the shear plane passes through the unthreaded part of the bolt A is equal to the gross cross-sectional area of the bolt A g. For full table with more Property Classes - rotate the screen! Metric Bolts - Fine Threads - Minimum Ultimate Tensile Loads ThreadAustria, Azores, Czech Republic, Denmark, Finland, Greece, Italy, Madeira, Poland, Portugal, Spain, Sweden According to EN1993-1-8 Table 3.4 the shear strength of the bolt may be based on the tensile stress area. The tensile stress area depends on the thread and it can be calculated according to ISO 898-1 Section 9.1.6.1. The number 1.0 is the thread pitch of the bolt, which is the distance between threads, in millimeters.
