T-Slot nut selection guide
Compare installation, profile and thread options
Start with the available profile access, then match the profile system, slot opening and metric thread. Open the product page for the exact dimensions, material and finish available for each model row.
2. Match the profile and thread
Select the GB or EU system, exact profile series, measured slot opening and metric thread shown in the same product row.
3. Choose temporary retention
A spring ball or leaf holds the nut temporarily before tightening. It does not create the final clamping force, which comes from the tightened bolt.
