Frequently asked questions
When should I use a 3 mm spacer instead of a taller one?
Use it when only a small, fixed gap is needed between two parts. For larger gaps, choose a taller spacer, such as the 6.35 mm or 9 mm versions.
Will my screw fit the 5.1 mm bore?
Check the screw's shank diameter against the 5.1 mm inner diameter before assembly. A screw thicker than the bore will not pass through the spacer.
