A deep dive into the specifications, applications, and advantages of NAS1102 CSK Screws.
A guide to calculating hole tolerances for bolted assemblies, covering examples for both metric and imperial through holes.
This guide explains two approaches to dimensioning holes on a 2D technical drawing: prioritizing hole position for non-critical assemblies, or critical mating components.
Positional tolerances, in order to determine the location of features, theoretical exact dimensions and a control feature frame can determine the locations of any feature (points, axes, planes and median surfaces). The tolerance zone is located symmetrically about the theoretical centre. For fixing locations, always use positional tolerance.For viewing or access holes, linear dimensions may…
