Compare the design strength for each limit states: Bolt design strength = 211 x 2 = 422 kips (CONTROLS) Yield of the member = 567 kips Rupture of the member = 435 kips Block Shear for the member = 496 kips Therefore, design strength of the tension splice is 422 kips. The individual parts of a bolt comprise a hexagonal head and a circular section shank, which may be fully or partly threaded. Geometric effects on compression loading similar joint configuration can give apparent bolt shear capacity 9% higher. 3 permits the use of ASTM A325 and A490 high-strength bolts. In Table J3. A325-14 Standard Specification for Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength (Withdrawn 2016) Products and Services / Standards & Publications / Standards Products You are being redirected because this document is part of your ASTM Compass® subscription. These are average values only. Mech_Engineer. These large tensile forces in the bolt clamp the connected plates together. Unbrako Structural Bolt Assembly - BS EN 14399, BS EN 15048, AS1252, IS 3757, ASTM A325, ASTM A490, F436, F959, F959M. Metric bolt grades and strength calculator was developed to show proof strength, tensile strength, Vickers / Brinell hardness, minimum breaking torque and stress area of metric bolts and screws made of carbon steel and alloy steel. A325 bolts from Glaser and Associates are available in two grades, type 1 and type 3, offering different mechanical and chemical properties for specific applications. Alma Bolt Company & Prime Fasteners 1-800-526-2200. Ramseier This work has· been carried our as part of the project on Large Bolted Connections, spon­ sored financially by t~e Pennsylvania Department. Shear and Tension Capacity of Stainless Steel Bolts. Metric bolt strength There have been several posts recently about bolting roll bars and finding replacement bolts etc. ASTM A490 series bolts are equivalent to ASTM A325 bolts in application and geometry, but are made to a higher strength. com offers 406 high strength a325 bolts products. Riveted joints behave more like snug-tightened joints, but the "pins" in this case are the rivets, and are typically about half the strength of A325 bolts. Bolt Shear Strength Considerations - Portland Bolt. Configurations: The system is available in Flush Tension Head, Flush Shear Head and Protruding Head styles. The various configurations considered in this test program include the thickness of the framing members and the stud spacing. 8, can be used for anchor bolts, but this is a high strength steel.
