Product Information

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°) = 1.1547⋅ s. The tensile stress area A s corresponds to the reduced cross-sectional area inside the threaded part of the bolt.

According to EN1993-1-8 § 3.6.1(4) the design shear resistance F v,Rd should only be used where the bolts are used in holes with nominal clearances not exceeding those for normal holes as specified in EN 1090-2 'Requirements for the execution of steel structures'. The standard coarse pitch thread metric bolt sizes are: M3, M3.5, M4, M5, M6, M7, M8, M10, M12, M14, M16, M18, M20, M22, M24, M27, M30, M33, M36, M39. v is a coefficient that takes values α v = 0.6 for bolt classes 4.6, 5.6, 8.8 or α v = 0.5 for bolt classes 4.8, 5.8, 6.8 and 10.9. When the shear plane passes through the unthreaded part of the bolt α v = 0.6. 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. Finally, it is important to ensure that the drill bit is sharp. A sharp drill bit will create a clean and precise hole, whereas a blunt drill bit can cause the hole to be too loose or too tight.

Combined shear and tension

According to EN1993-1-8 Table 3.4 the shear strength of the bolt may be based on the tensile stress area.

The second number corresponds to the ratio of yield strength to ultimate strength e.g. 60% for class 4.6 leading to a yield strength of 0.60 × 400 MPa = 240 MPa. When drilling into wood, it is important to select the correct type of drill bit for the job. Wood-specific drill bits are designed to be softer than metal or masonry-specific drill bits, allowing them to cut into the wood without damaging it. When installing an M12 anchor bolt, the bolt should be tightened until the head of the bolt is flush with the surface of the material into which it is installed. The bolt should be tightened until it reaches its maximum torque capacity, as indicated in the manufacturer’s instructions. Over-tightening could cause damage to the bolt, while under-tightening could reduce the bolt’s holding strength. Is an M12 Anchor Bolt the Best Option for Heavy-Duty Applications? The width of the hexagon nuts across flats s is specified in ISO 898-2 Table A.1 for bolt sizes M5 to M39. Therefore, based on the equations above, the bearing resistance of the bolt F b,Rd is not affected by the distances e 1, p 1, e 2, p 2 when the following conditions are satisfied:The design shear resistance of bolts F v,Rd as given in EN1993-1-8 Table 3.4 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 §3.6.1(4). 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. 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 § 3.7(1). For this case elastic linear distribution of internal forces should be used as specified in EN1993-1-8 §3.12. The size of the drill bit is important when installing anchor bolts in concrete. For an M12 anchor bolt, it is recommended to use an 18mm drill bit to ensure a secure installation. The drill bit should be of the same diameter as the anchor bolt so that the concrete can grip it firmly. What size drill bit for M10 concrete bolt would be suitable for an M10 anchor bolt. Anchor Bolt Size 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. Yes, an M12 anchor bolt can be used in masonry surfaces. It is important to use the appropriate drill bit size when installing an anchor bolt, as it will determine the strength of the anchor. Here are some tips for selecting the right size drill bit for an M12 anchor bolt:

According to EN1993-1-8 § 3.8(1) 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 3.5. 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.

Definition of standard metric bolts

A 12mm drill bit is the ideal size for an M12 anchor bolt. This sized drill bit will ensure the proper installation of the anchor bolt. To ensure the best results, it is essential to use the correct drill bit size and to make sure the anchor bolt is fixed into a solid surface. References For preloaded bolted connections which are slip-resistant at the Serviceability Limit State or the Ultimate Limit State the corresponding shear load F v,Ed should not exceed the design slip resistance as specified in EN1993-1-8 §3.9 and Table 3.2. Only bolt assemblies of classes 8.8 and 10.9 may be used as preloaded bolts. Anchor bolts are embedded in the concrete to provide a secure hold and to resist shear and tension forces. Generally, anchor bolts are made from steel and have a hex head to enable tightening with a wrench. According to EN1993-1-8 Table 3.4 the bearing resistance F b,Rd for bolts in holes other than normal should be multiplied by the following reduction factors: Oversized holes = 0.8, slotted holes with longitudinal axis perpendicular to the load transfer direction = 0.6. The first number of the bolt class corresponds to the ultimate strength e.g. 400 MPa for classes 4.x, 500 MPa for classes 5.x, 600 MPa for classes 6.x, 800 MPa for classes 8.x, and 1000 MPa for classes 10.x.
