Quick Answer Bolt hole alignment is the single most critical quality parameter in angle steel tower fabrication. A self-supporting lattice tower is assembled from hundreds or even thousands of angles and connection plates using bolts—and any deviation in a single connection hole may render on-site erection impossible. The industry standard for hole position tolerance is ±0.5 mm per GB...
