thread engagement for 10-24 socket head cap screw

thread engagement for 10-24 socket head cap screw

(OP)
I am in the hydraulic industry.  Please help me determine the min. thread engagement for a 10-24 socket head cap screw grade 8.  I am using 4 of these screws to mount a size D03 hydraulic valve on an aluminum manifold.  My maximum pressure is 3,000 psi.  

Thanks for your help.

The equations you need are in this thread:

Thread725-35222

Are the internal threads in the aluminium manifold?  If so, you need to know the ultimate shear strength (or 0.6 · ultimate tensile strength) of this piece.

RE: thread engagement for 10-24 socket head cap screw

What is the area D03 hydraulic valve which the pressure reacts on?

RE: thread engagement for 10-24 socket head cap screw

this might be too simplistic but, i use 2D as a rule of thhumb.

RE: thread engagement for 10-24 socket head cap screw

The pressure would be acting on an area of 0.304 in² with a DO3 size valve.
