Factory Pro FP-M-AC5010BK black collars are useful for hobbyists who need repeatable spacing. These 5mm x 1.0t collars come in a 10 piece pack and are handy for tuning wheel play and linkage clearance.
Use these collars to adjust suspension spacing, set bearing endplay, or fine tune gearbox alignments. Their common sizing makes them versatile for custom setups and repairs across many small-scale models.
The collars are made to retain shape under normal hobby use so they keep spacing stable during running and servicing. They work well as replacement shims or for experimenting with small geometry changes.
