M14 (14mm x 40mm) Hex Bolt (Fully Threaded Setscrew) - Steel (Pack of 5)

Product Information

The interaction between shear and tension is expressed in EN1993-1-8 Table 3.4 according to the following linear relation: 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 raised, helical rib or ridge around the interior or exterior of a cylindrically shaped object. Threads are found on screws, nuts, and bolts. The diameter equal to the external diameter of the threads or the overall diameter of the part. (Nominal diameter is more of a label than a size. For example, a bolt and nut may be described as being ½” diameter. But neither the external threads of the bolt nor the internal threads of the nut are exactly .500 in diameter. In fact, the bolt diameter is a little smaller and the nut diameter a little larger. But it is easier to specify the components by a single size designation since the bolt and nut are mating components.)

Minimum end distance, edge distance, and spacing for bolt fasteners according to EN1993-1-8 Table 3.3 (rounded up to nearest mm) Refer to the charts below, which show the ideal tightening torque for each bolt grade for a variety of sizes.Metric class 12.9 bolts are made from quenched and tempered alloy steel and see the most use in heavy-duty applications. Compare the bolts you have with the diagrams below, then refer to the appropriate chart to see the ideal tightening torque. Metric Bolt Torque Chart The calculated strength properties for coarse pitch thread bolts may be used conservatively for fine pitch thread bolts. According to EN1993-1-8 Table 3.4 the shear strength of the bolt may be based on the tensile stress area.

They have a proof load of 970 MPa, minimum yield strength of 1100 MPa, and a minimum tensile strength of 1220 MPa. Class 12.9 bolts come in sizes ranging from 1.6 mm to 100 mm. 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. 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. 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.Coarse threads are those with larger pitch (fewer threads per axial distance), and fine threads are those with smaller pitch (more threads per axial distance). Coarse threads have a larger threadform relative to screw diameter, whereas fine threads have a smaller threadform relative to screw diameter.
