резьбовые соединения

[bsv687]

Помогите правильно перевести три термина в указнном контексте

Benchmark -
If present check for benchmark. Measure the benchmark and verify its proper location. If the benchmark are not the proper length the connection shall be rejected.

Straight edge -
Place a straight edge across the face of the tool joint and measure the distance from the straight edge to the make-up shoulder with a precision rule.

Root pullout -
Using the profile gauge locate the last point of full thread depth by placing the gauge in the last groove and moving it toward the run out until the root pullout begins to lift the gauge out of the groove. Move to the last point where the gauge fits solidly in the root and mark the location of the gauge on the pin base.
