- Spinner Caps to use with fidget spinners
- Designed to be screwed together. Post is sized for M3x.5 tap*. Suggested M3 screw length 6mm-8mm Flat head screw
The fitment is designed to be snug for 8mm bearing shaft diameter. If it is too tight some light sanding may be required.
*Stainless Steel is VERY HARD and very difficult to tap. I would suggest a slightly oversized pilot and using a very high grade tap with cutting fluid. It can be done but I usually tap 1/8-1/4 turn at a time. Aluminum and Brass material options cut threads much more easily.
