Perpendicularity | GD&T Basics

I can determine the size and position tolerance on the hole based on thread-engagement and lining up the hole with the mating part, but I’m not sure what considerations inform the perp tolerance. Considering that the screw is about 12mm long, it will naturally align to the blind hole into which it is threading.

Shoulder Screws Selection Guide | Engineering360

Precisions-grade shoulder screws will have tolerances from .0005 to .0015 inches (.013 and .038 mm) below their nominal size. Commercial grade screws have varying screw tolerances. For all imperial unit screws, tolerance range is .002 and .004 inches below the labeled size. Metric tolerances change according to the predetermined diameter.

Thread standards and tapping hole tolerances

Normal tap tolerance is ISO 2 (6H), which generates an average quality fit between screw and nut. Lower tolerance (ISO 1) generates a fine fit without a gap on the flanks between screw and nut. Higher tolerance (ISO 3) generates a rough fit with a large gap. This is used if …
