NUT,3/8X26 THIN

A 3/8 x 26 thin nut, PN 21-0152 (also listed as S1 52 / S152).

PN · 21-0152
Available in 4 sizes:

This is a 3/8 x 26 thin nut, part number 21-0152, also known by the older shop codes S1 52 and S152. The catalog description just calls it a thin half-nut in that size, and that's about all our records give us on it.

We don't have a figure title or model tie to point to for this one, so we can't say exactly where it lives on the bike beyond being a small fastener in that thread size. If you've got a parts book reference for where yours calls for it, that's the best way to confirm it's the right nut for the job.

Given how sparse our own record is on this part, give the shop a call if you want to double check fitment before ordering.
