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

Product Information

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. 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.

If you properly torque the bolts, they will provide the maximum amount of clamping force under load. 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.

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. They are made of quenched and tempered medium carbon steel and can be plated with a variety of materials, most commonly zinc. for long joints where the distance between the centers of the end fasteners measured in the direction of load transfer is more than 15 d the design shear resistance F v,Rd of all the fasteners should be multiplied by the reduction factor β Lf specified in EN1993-1-8 equation 3. 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.

For bolts with cut threads where the threads do not comply with EN 1090 the relevant resistances should be multiplied by a factor of 0. 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. For this case elastic linear distribution of internal forces should be used as specified in EN1993-1-8 §3.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. 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. Ultimate Tensile and Proof loads for metric bolts according ISO 898-1 "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".
