Permanent manufacturer’s identification markings (Supplementary Requirement S2) and/or permanent grade identification markings (Supplementary Requirement S3) can be specified on the inquiry and purchase order.
The end of each anchor bolt intended to project from the concrete requires a color code to identify the grade as follows: For tensile loads, if the user has 1, 2, or 4 bolts in a rectangular pattern, the user should provide c 1 through c4 and s1 and s2.

For other numbers of bolts and bolt patterns, the user needs to calculate and input A n and Av. Design resistance Anchor size M6 M8 M10 Eff. Testing and ana- lytical studies in Germany in the 1980s led to the development of a design pro- cedure for headed-stud anchors known as the Kappa method. Learn more about common configurations of straight rods, bent anchor bolts, and headed anchor bolts that are the three different bolt designs this specification covers. For 1, 2, or 4 bolts in a rectangular pattern, this spreadsheet will calculate A n and Av. F1554 grade 105 – 105 ksi minimum yield strength.F1554 grade 55 – 55 ksi minimum yield strength.F1554 grade 36 – 36 ksi minimum yield strength.GradesĪSTM F1554 consists of three grades that correspond to the minimum yield strength of the steel. Chemical requirements, mechanical properties, and dimensional tolerances are all covered under the F1554 specification. Place a steel bolt inside and tighten with a torque wrench to expand the 2 sets of flanges.ASTM F1554 is the newest construction fastener specification developed by the American Society for Testing and Materials and covers steel anchor bolts intended for anchoring structural supports to concrete foundations.
Insert a double expansion anchor into a hole 1/8 inch deeper than the anchor. These anchors have flanges that expand at the top and base of the anchor to resist vibration. Insert the steel screw and tighten with a screwdriver. Drill a hole deeper by 1/8 inch than the leadwood anchor, insert the anchor, and tap it in with a hammer. Use longer leadwood anchors for softer materials. They are suitable for brick, poured concrete, and concrete block.
Leadwood anchors surround a sheet steel bolt. Insert the shield first into a drilled hole, place the bolt inside and tighten with a torque wrench. The lag shield encloses the bolt and opens into a 2-sided wedge nearly as long as the bolt for a secure hold in hard and soft materials. Use the lag shield anchor bolt where the material being fastened may be subject to vibration. Strike anchor bolts can fasten aluminum or steel concrete right-angled ties to concrete and brick quickly.

Concrete Capacity Design (CCD) Approach for Fastening to Concrete. Insert the bolt through the nut and washer brace into a hole drilled to the width of the strike bolt. Strong and sturdy, strike anchor bolts are set with a hammer instead of a torque wrench. Sleeved anchor bolts work well in brick and concrete. Tightening the bolt after insertion opens the sleeve casing which flares out about 1/8 inch. The connection can be made by a variety of different components: anchor. Design so that anchor strength is governed by steel tensile or shear yielding. The sleeve anchor bolt has an external casing that flares at the base to hold the bolt snugly in the concrete. Anchor bolts are used to connect structural and non-structural elements to concrete. When the bolt is tightened, the wedges open 1/16 inch at the base to embed the bolt securely. The wedge anchor bolt goes into a hole drilled to the width of the wedge, and 1/2 inch longer than the bolt. The wedge anchor bolt is one of the most popular due to its strength, rust resistance, and ease of insertion.
