Our metric stud bolt to nut table is meant to help determine the correct size bolt or nut for your purpose. The tensile stress area A s corresponds to the reduced cross-sectional area inside the threaded part of the bolt. Coarse threads have a larger threadform relative to screw diameter, whereas fine threads have a smaller threadform relative to screw diameter.

use in applications such as access panels, number plates and many anti-vandalism securing solutions. 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. For this case elastic linear distribution of internal forces should be used as specified in EN1993-1-8 §3. 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.

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. Zinc Flake coated high tensile steel class 10 - a higher tensile non-stainless grade for screws and bolts. UNBRAKO® branded and manufactured to be stronger than the other size for size high tensile versions.

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. 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. The difference between a hex set bolt and a standard hex bolt is that hex bolts tend to have a shaft, whereas a hex set bolts do not.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. For preloaded bolted connections which are slip-resistant at the Serviceability Limit State or the Ultimate Limit State the corresponding shear load F v,Ed should not exceed the design slip resistance as specified in EN1993-1-8 §3. A popular nut type, with a more unusual Fine Thread Pitch for when more thread engagement is required. 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.

Copper Alloy - Copper has good corrosion resistance and high tensile strength, allowing it to withstand high-pressure and high temperature conditions.where e 1 is the distance between the center of the end bolt and the end of the plate measured parallel to the load direction, p 1 is the distance between the centers of neighboring bolts measured parallel to the load direction, and d 0 is the diameter of the bolt hole.
