NUT NYLOC 1/4X26 THIN - Replaces 70-5269
A 1/4 inch, 26 TPI thin nyloc nut used on handlebar/control lever and toolkit/air filter fittings, replacing the older 70-5269 part number.
This is a nyloc nut in a 1/4 inch by 26 TPI thin pattern, listed in our records as replacing the earlier 70-5269 number. The nyloc design has a nylon insert built into the nut that keeps it from working loose under vibration, which is exactly the kind of hardware you want on control levers and fittings that see constant movement.

It shows up in the parts books under the handlebar and control lever listings as well as the battery, toolkit, and air filter section, so it's one of those small fasteners that gets used in more than one spot on the bike. The catalog spans a run of years through the 1960s into 1970, meaning this nut turns up across a good number of model listings rather than being tied to one specific bike or year.
If you're chasing down the old 70-5269 number from an earlier parts book, this 18/053 is the current listing for the same nut. Worth keeping a few on hand since nyloc hardware in this size gets used in more than one place on the bike.
