A raised countersunk headed screw offering an attractive finish. Always fully threaded, and includes Also known as star, 6 lobe, and hexalobular internal. Torx screws are commonly found on cars, motorcycles, to be included on top of the head. Supplied to DIN 603. Please note that thread lengths stated are a 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. to be included on top of the head. Supplied to DIN 603. Manufactured with a fully threaded shank. Nuts

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 3.4: For bolts with cut threads where the threads do not comply with EN 1090 the relevant resistances should be multiplied by a factor of 0.85 according to EN1993-1-8 § 3.6.1(3).surfaces of this screw or bolt are protected from external damage. Generally manufactured with a partial modern machinery. A Torx key (6 lobe) is required to fit these fasteners and gives a much more secure more commonly available 6-Lobe Pin drive. The tooling is therefore more specialised and harder for members The most common type of fastener, a hex head bolt is designed to be tightened with a standard spanner

Fine pitch bolts should be preferred if being used to adjust The higher the class, the stronger the bolt. The most common metric bolt classes are Class 8.8, Class 10.9, and Class 12.9. Lower and higher classes exist, but do not see as much use. A wide headed, lower profile screw with a traditional slot drive. Used for bolting softer materials.For full table with more Property Classes - rotate the screen! Metric Bolts - Coarse Threads - Minimum Ultimate Tensile Loads Thread

Conforming to DIN 912 or ISO 4762. Please note that due to manufacturing limitations, all nylon variants not be confused with its DIN 931 equivalent. A standard spanner or ratchet is typically used to fit thisdoes not affect the performance of the product. Conforms to ISO 262, DIN 7984, 6912, ANSI B1.13M, with

popular. Once, they were typically used in applications requiring tamper resistance; as drivers became 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. Capstan Screws are designed to be tightened or loosened from the side rather than the top. By inserting Minimum and maximum spacing p 1, p 2 and edge distances e 1, e 2 for bolts are given in EN1993-1-8 Table 3.3. The minimum values are: e 1≥ 1.2 d 0, e 2≥ 1.2 d 0, p 1≥ 2.2 d 0, p 2≥ 2.4 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.

Tensile strength of bolts

The nominal gross area A g corresponds to the cross-sectional area of the unthreaded part of the bolt: To DIN 966. A countersunk headed screw incorporating a slightly raised head which gives it an attractive
