M14 bzp hexagon head bolts are manufactured from steel and have a diameter of 14 mm, conform to DIN 931 spec, and have a partial thread. Screw extractor is used counter-clockwise to remove broken right-handed bolts from threaded holes without damaging threads. In general the stress area of fine pitch thread bolts passing through the threaded part is larger as compared to the coarse pitch thread bolts.

In general it is older models which use the thinner M12 bolts and newer models which use the M14 thread size. In addition for countersunk bolts the bearing resistance F b,Rd should be based on a plate thickness t equal to the depth of the connected plate minus half the depth of the countersinking. The 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.
The calculated strength properties for coarse pitch thread bolts may be used conservatively for fine pitch thread bolts. d 0, where d 0 is the diameter of the hole, e 1, p 1 are measured parallel to the load transfer direction and e 2, p 2 are measured perpendicular to the load transfer direction. Minimum end distance, edge distance, and spacing for bolt fasteners according to EN1993-1-8 Table 3. The tensile stress area A s corresponds to the reduced cross-sectional area inside the threaded part of the bolt. Otherwise the design resistance of a group of fasteners should be taken as the number of fasteners multiplied by the smallest design resistance of any of the individual fasteners as specified in EN1993-1-8 § 3.

Zinc Flake coated high tensile steel class 10 - a higher tensile non-stainless grade for screws and bolts. Zinc Flake coated high tensile steel class 12 - a higher tensile non-stainless grade for screws and bolts.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. Minimum and maximum spacing p 1, p 2 and edge distances e 1, e 2 for bolts are given in EN1993-1-8 Table 3.

Pitch is the distance from the crest of one thread to the next or the distance from one thread groove to the next, measured from crest to crest. 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 smallest or largest pitch diameter that fits onto a screw or into a nut, including all of the form deviations such as lead, thread angle, taper, and roundness. By approximately ignoring the corner rounding for a perfect hexagon the relation of the distance across points s' and the distance across flats s is s' = s / cos(30°) = 1. Car wheel nuts and bolts are complicated and it is important to get the correct fitment for your car.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 design shear resistance F v,Rd should only be used where the bolts are used in holes with nominal clearances not exceeding those for normal holes as specified in EN 1090-2 'Requirements for the execution of steel structures'.
