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

Product Information

The design resistance of a group of fasteners may be taken as the sum of the design bearing resistances F b,Rd of the individual fasteners provided that the shear resistance F v,Rd of each individual fastener is greater than or equal to the design bearing resistance F b,Rd. Refer to the charts below, which show the ideal tightening torque for each bolt grade for a variety of sizes. bolts are made from quenched and tempered alloy steel and see the most use in heavy-duty applications.

Therefore for countersunk bolts the calculated tension resistance F t,Rd should be reduced by a factor of 0. The charts below gives the dimensions for Hexagon head, Socket cap, Low head socket cap, Socket countersink, Socket button and Shoulder screw with Metric Threads. 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.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. Identify the class by the embossed number on the head, then find the size of your bolt in the chart. The bolt’s class indicates its material strength, with higher numbers meaning higher tensile and yield strength. 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.

Depending on size, they have a proof load of 580-600 MPa, minimum yield strength of 640-660 MPa, and a minimum tensile strength of 800-830 MPa.They have a proof load of 970 MPa, minimum yield strength of 1100 MPa, and a minimum tensile strength of 1220 MPa.
