With an on-size buttress thread with the 7* angle facing the piston, the seal (usually an o-ring or quad ring) will drop into the thread space and lock the piston in place when you try to disassemble it. Thread dimensions shown without tolerances are related to the basis for connection design and are not subject to measurement to determine acceptance of product. 3, how do you measure a buttress thread? The buttress thread with 45° flank angle is used on hydraulic presses. 5/32 thread turn for sizes 8-5/8 and smaller, 1/5 thread turn for sizes 9-5/8 and larger, and 1/5 thread turn for all 10-thread gauges.
