Thread depth for maximum strength
WebA screw jack shown in figure (8) with a 1-in., double-thread Acme screw is used to raise a load of 1000 lb. A plain thrust collar of mean 1.5 in diameter is used. Coefficients of running friction are estimated as 0.12 and 0.09 for f and f c respectively. a. Determine the screw pitch, lead, thread depth, mean pitch diameter, and helix angle. b. WebAug 1, 1995 · As a general rule for holes 1 1/2 to 3 diameters deep, the hole should extend approximately 1 1/2 diameters beyond the tap’s deepest point. Threads deeper than 3 diameters may require even more clearance at the bottom of the hole, because the deeper threads will produce a greater volume of chips.
