Product Information

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 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 concrete or masonry, it is important to use a hammer drill, as this will generate enough force to create the hole. Additionally, a masonry bit should be used, as this is designed to withstand the wear and tear caused by drilling into hard surfaces. It is also important to make sure that the drill bit is sharp and in good condition, as a dull bit may not create the hole correctly and could cause the anchor bolt to become loose.

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. 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. Twist Drill Bits are the most common type of drill bit and are used for drilling into wood, plastic, and metal. They have two flutes that spiral down the body of the bit, and their sharp edges create a hole when rotated. 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.Hole Saws are designed to cut large holes in wood, plastic, and metal. They feature a circular saw blade that is designed to cut a hole in one pass. 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. The tensile stress area A s corresponds to the reduced cross-sectional area inside the threaded part of the bolt. To sum up, selecting the right drill bit for the job is essential for ensuring a successful result. It is important to select the correct drill bit size for anchor bolts, as well as the correct type of drill bit for the job. It is also important to ensure that the drill bit is sharp, as this will create a precise hole. Frequently Asked Questions What other types of drill bits can be used for an M12 anchor bolt? The calculated strength properties for coarse pitch thread bolts may be used conservatively for fine pitch thread bolts.

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 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: The interaction between shear and tension is expressed in EN1993-1-8 Table 3.4 according to the following linear relation: 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 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. 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 Step Bits are used for creating holes in various materials. They feature a stepped design that is designed to gradually increase the size of the hole as it is being drilled. Auger Bits are used to drill holes in wood. They feature a curved tip that is designed to pull material out of the hole as it is being drilled. When installing an anchor bolt into a masonry surface, it is important to ensure that the anchor bolt is securely fastened. This can be achieved by using an appropriate drill bit size, as well as using the correct techniques for installation. How Tight Should an M12 Anchor Bolt be Secured?

Anchor bolts are used for installing fixtures and supports into concrete and masonry. The size drill bit required for an M12 anchor bolt is typically 12mm in diameter. This size is suitable for most applications and will ensure a secure fit for the anchor bolt. It is important to ensure that the drill bit is the correct diameter; using a drill bit that is too small will not provide sufficient grip for the anchor bolt and could lead to the bolt becoming loose or failing altogether.

Combined shear and tension

When it comes to drilling, the right drill bit for the job is essential for ensuring a successful result. For an M12 anchor bolt, the ideal drill bit size is 12mm. It is important to select the correct drill bit size for anchor bolts as using too large a bit can result in the anchor bolt being too loose and too small a bit can lead to the anchor bolt being too tight. 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. By using the correct size drill bit, you can also ensure that the anchor bolt has a secure fit and is not easily removed. Additionally, using the right size drill bit can reduce the amount of time it takes to install the anchor bolt, as it can help to ensure that the hole is drilled with the correct dimensions. Finally, using the right size drill bit can also help to reduce the risk of injury due to incorrect drilling, as it can help to ensure that the hole is drilled safely and without any risk of the drill bit slipping or breaking. The Different Types of Drill Bits Other types of drill bits that can be used for an M12 anchor bolt include masonry drill bits, SDS drill bits, and countersink drill bits. Masonry drill bits are designed for drilling into concrete and masonry, which makes them ideal for anchor bolts. SDS drill bits are designed for use with SDS (Slotted Drive System) drill machines and are ideal for drilling through harder surfaces. Countersink drill bits are designed for drilling pilot holes for anchor bolts and are designed to create a conical shape for the anchor bolt to fit into. Can an M12 Anchor Bolt be Used in Masonry Surfaces?

Forstner Bits are designed to drill flat-bottom holes in wood. They feature a center drill bit that is designed to create a flat-bottomed hole as it is being drilled. According to EN1993-1-8 Table 3.4 the bearing resistance F b,Rd of the bolt is not affected by the spacing p 1, p 2 and edge distances e 1, e 2 provided that the following limits are observed: e 1≥ 3.0 d 0, e 2≥ 1.5 d 0, p 1≥ 3.75 d 0, p 2≥ 3.0 d 0. The width of the hexagon nuts across flats s is specified in ISO 898-2 Table A.1 for bolt sizes M5 to M39.For typical coarse pitch thread bolts the standard sizes are: M3, M3.5, M4, M5, M6, M7, M8, M10, M12, M14, M16, M18, M20, M22, M24, M27, M30, M33, M36, M39. 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. The tensile stress area depends on the thread and it can be calculated according to ISO 898-1 Section 9.1.6.1. An anchor bolt is a fastener used to attach objects to concrete. It consists of a threaded end, to which a nut and washer can be attached for the external load. The most common types of anchor bolts are through-bolts, expansion bolts, and lag screws. 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.
