Frequently asked questions
Which fastener fits this spacer?
A 5.1 mm bore accepts a fastener with a shank of about 5 mm, such as an M5 bolt. Check the bolt diameter before assembly.
Can I use it to electrically isolate two metal parts?
No. Aluminum conducts electricity, so use an insulating washer or spacer if the spacer must separate two live or electrically different parts.
