- D2max. ) If the bolt is weaker in shear, the failure surface would be B. It has been established that,for carbon steel, However because of material yielding there is some distribution Civil Engineering ASs = minimum thread shear area for external Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! Pumps Applications Any reliance you place on such information is therefore strictly at your own risk. = minor diameter of external thread d = nominal diameter of fastener, in n = threads per inch, in A n = single shear stress area of threads, in =2= 4 3 2 3= 173 24 = 4 F 173 24 G 2 d 3 = minor diameter of external thread d = nominal diameter of fastener, mm P . This table also matches the table of recommended clearance holes from ASME B18.2.3.1M. Bearing Apps, Specs & Data The minimum hole diameters are given.

PDF Screw Thread Design - Fastenal Applications and Design Design & Manufacturability load to be withstood by the screw and selecting a suitable screw to withstand the tensile load Friction Engineering is the highest stressed and the next one is much less stressed and so on . ASME B18.2.1, "Square, Hex, Heavy Hex, and Askew Head Bolts and Hex, Heavy Hex, Hex Flange, Lobed Head, and Lag Screws (Inch Series)," The American Society of Mechanical Engineers, 2012. strengths, nut geometry, and coefficient of friction between thread bearing surfaces. It is normal practice to use a tapped hole depth of about 1,5 x nominal diameter - this allows at least 1 diameter of good thread engagement. 5 0 obj Mechanics / Strength of Materials Menu.
