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

Product Information

use in applications such as access panels, number plates and many anti-vandalism securing solutions. Refer to the charts below, which show the ideal tightening torque for each bolt grade for a variety of sizes.

the bearing resistance F b,Rd for bolts in holes other than normal should be multiplied by the following reduction factors: Oversized holes = 0. 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'. Want to determine what size clearance hole for Imperial, for example, 3/8″, then check out our chart here.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. 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. 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. They have a proof load of 830 MPa, minimum yield strength of 940 MPa, and a minimum tensile strength of 1040 MPa.

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. Zinc Flake coated high tensile steel class 12 - a higher tensile non-stainless grade for screws and bolts. where bolts transmitting load in shear and bearing pass through packing plates of total thickness t p greater than d / 3 the design shear resistance F v,Rd should be multiplied by the reduction factor β p specified in EN1993-1-8 equation 3. If you properly torque the bolts, they will provide the maximum amount of clamping force under load. The punching resistance of the bolt B p,Rd should be verified against the applied tensile load F t,Ed in accordance with EN1993-1-8 Table 3.

Proof load is defined as the maximum tensile force that can be applied to a bolt that will not result in plastic deformation. 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.

If you might need to look up the ideal tightening torque for metric class bolts again, why not bookmark this page so that you can refer to it more easily in the future? 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.Minimum end distance, edge distance, and spacing for bolt fasteners according to EN1993-1-8 Table 3. The resulting hole diameter d 0 for each type of hole (normal, oversize, short slotted, long slotted) is determined by adding the nominal clearance given in EN 1090-2 Table 11 to the nominal diameter d of the bolt. 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.

Compare the bolts you have with the diagrams below, then refer to the appropriate chart to see the ideal tightening torque. that due to the nature of the surface finish on Unbrako products, some surface corrosion may be evident. The calculated strength properties for coarse pitch thread bolts may be used conservatively for fine pitch thread bolts.For this case elastic linear distribution of internal forces should be used as specified in EN1993-1-8 §3. 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. 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. 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.
