Frequently asked questions
What is a spacer used for?
A spacer keeps a fixed gap between two mechanical parts, such as a frame and a mounting plate, so screws can be tightened without crushing or misaligning the parts.
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.
