DO NOT use these valu es if a different torque valu e or . New At Muscle & Strength View all new. Keep units consistant when performing calculations. Required strength in shear (factored shear load), kips d b Nominal diameter of bolt, in. To be fair, the higher the grade of bolt, the harder it becomes as rated by the rockwell scale. English bolts have radial lines on their head to identify the grade, or strength class. tightness of fasteners peri odically. Extensive data on Metric bolt properties is here, and the same site's home page gives links to a lot of other materials, analysis, and fastener data. A bolt commonly shears where its head meets the threads. Strength / Mechanics of Materials Beam Deflection & Structural Analysis. Shank (1) €shear capacity of the unthreaded section (plain shank) of the fastner.

The minimum tensile strength of a 12.9 bolt is 1220 MPa. Google use cookies for serving our ads and handling visitor statistics. Allen head bolts can easily be identified as they require the use of an allen wrench. Shear bolts are de signed to fail under pr edetermined . Check . The identification of high-strength structural bolt and nut assemblies can be readily made from the bolt head and nut markings (see Ref. Metric Threads Thread Size Tensile Class 10.9 Class 12.9 Area Class 8.8 Class 9.8 Proof Load, Yield, & Tensile Chart GFC Engineering & Testing Center 1524 East 14 Mile Road • Madison Heights, MI 48071 • 248-307-0567 • www.genfast.com Proof Load, Yield & Tensile Strength Chart Metric. Proof load is defined as the maximum tensile force that can be applied to a bolt that will not result in plastic deformation. The two figures indicate the tensile and yield strengths of the bolt or screw. P t = p t A t Exact . Always replace shear bolts with identical property . There are 6.8947573 MPa per ksi.

The failure will occur at the root of the nut threads. Notes – all shear capacity values are given in kilo-Newtons (kN) – all values represent the minimum breaking load in ‘single’ shear. Most stainless is non-magnetic, though 410 Hardened stainless is ALWAYS magnetic. scenario, the bolt threads will shear out the nut threads. Bolt Grade Markings and Strength Chart. The materials of our particular concern are: Steels - low tensile (mild steel) - high tensile - stainless steel: The major factor in determining the load a material can carry is its tensile strength, which is related to its hardness. Metric bolt grades and strength calculator 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 with designations 4.6, 4.8, 5.8, 8.8, 9.8, 10.9 and 12.9.
