When dead loads counteract the effect of the other applied loads, such as for overturning, uplift, sliding, or stress reversal, the load factor is taken as 0.9. The load factor applied to the companion load is less than or equal to 1.0 in order to account for the reduced probability of having
A shoulder separates the unequal lengths of thread. The tap end is the short threaded end and its thread length is about 1.25 times the diameter of the stud; they are available with an interference thread fit at the tap end. The long threaded end is the nut end. Unlike inch series studs, metric stud length is the combined length of the nut end and unthreaded shoulder and doesn't include the tap end. RESILIENT SEATED AND DOUBLE OFFSET VALVES Engagement Equal to the Bolt Diameter = Length of Bolt Stud Length Washer Thickness + Nut Thickness + Flange Thickness + Minimum Stud Engagement Equal to the Stud Diameter = Length of Stud (Plus 2 Threads for Studs) NOTE:Lug Threads may be tapped from both sides and therefore tap may not be continuous.

Sep 26, 2005 · An old rule-of-thumb³ is that in a threaded hole in steel, the length of engagement should be at least 1.5 times the diameter of the screw, and in cast iron or brass, 1.8 to 2 times the diameter. Blind holes should be at least half a diameter deeper than the length of engagement. 1. ANSI B18.6.3-1972(R1991) 2.
