Product Description
BSCY Cycle Thread Carbon Steel Hexagon Die Nuts – 26 TPI
Carbon steel hexagon die nuts for cleaning and restoring existing BSCY cycle threads. Available in four nominal thread sizes, each with a pitch of 26 threads per inch.
The external hexagon allows the die nut to be turned with a suitable spanner or socket, making it useful for maintenance and restoration work on components using matching cycle threads.

Selection and Use
Confirm both the diameter and cycle thread form before use. Other thread systems can share the same diameter and TPI while having a different thread profile.
Align the die nut squarely with the existing thread, use a suitable cutting lubricant and turn carefully without forcing. Clear debris regularly and inspect the finished thread. Replace components with substantial thread damage.
Ordering
Select the required nominal thread size from the available options. Supplied as one die nut in the selected size.
