Good quality! The screw rack is small in size. Below are the amount of holes it provides for screw size of 1.5mm, 2.0mm and 2.7mm.
Holes for 1.5mm (6, 8,10……….20mm) 5 holes each size (40 holes)
Holes for 2.0 mm (8, 10, 12……….28mm) 6 holes each size (66 holes)
Holes for 2.7mm (10, 12, 14……….30mm) 6 holes each size (66 holes)
Total holes (1.5, 2.0 and 2.7) = 172
