  • Torque Values Stainless Steel Bolt Table Chart. ANSI Hardware Design Guide Design Torque and Force Calculations. Recommended Bolt Torque Values for Stainless Steel and Nonferrous Fasteners (inch series). The following torque values are suggested maximums based upon actual lab testing on clean and dry or near dry fasteners. For other friction ...
The applied torque causes the bolt to "climb" the thread causing a tensioning of the bolt and an equivalent compression in the components being fastened by the bolt. The preload developed in a bolt is due to the applied torque and is a function of the bolt diameter, the geometry of the threads, and the coefficients of friction that exist in the ...

  • The grade corresponds to the minimum yield strength of the anchor bolt. A307: Grade C of the A307 specification formerly covered anchor bolts, but in 2007 was replaced by F1554 Grade 36. Theoretically, Grades A and B could be used as anchor bolts, but technically they are not anchor bolt specificaitons.

    The widely recognized engineering formula, T= K x D x P (to be explained later in this article), was used to provide the chart's values, but it must be understood that every bolted joint is unique and the optimum tightening torque should be determined for each application by careful experimentation.

    A common type of concrete bolt is the cast-in-place anchor bolt. This is a threaded bolt that has been set in place and cast into a section of concrete, generally a building foundation or slab. The bolt threads at the end of the steel rod protrude from the concrete, and a washer and nut are used to hold the object being secured in place.

    Scope The ASTM F3125-15 specification consolidates and covers high strength structural bolts, both Hex Head & TC Bolts, that previously fell under A325, A490, F1852 & F2280. Bolts manufactured under this specification come in sizes from 1/2″ to 1-1/2″ inclusive. For bolts that do not fall under the diameter and length requirements for the above grades …

Re: anchor bolts after the concrete has set??? Someone already posted the link above; but the Titan anchor bolt from simpson is a good product. I have seen video pullout strength tests comparing the titan with standard j-bolts and the Titan is quite impressive. The concrete actually fails before the bolt. I no longer use the j-bolts.
Feb 16, 2018 · The Power-Bolt+ anchor is a torque controlled, heavy duty sleeve style anchor which is designed for consistent performance in cracked and uncracked concrete. Suitable base materials include normal-weight concrete and sand-lightweight concrete. The anchor is manufactured with a zinc plated carbon steel bolt, sleeve, cone and expansion clip.
