Replacement Bolt for Pro Style Dumbbells - 5/8" Diameter
Replacement bolt for pro style dumbbells. Includes one (1) 5/8" fine threaded bolt.
Earlier SDH dumbbell handles used 1/2" diameter Allen bolts which break easily on heavier dumbbells. Later SDH handles employ 5/8" diameter bolts that are much, much stronger and can stand up to more abuse without breaking.
All of the SDH dumbbell handles we offer use 5/8" diameter bolts. If you need to replace older 1/2" diameter bolts, contact us with your requirements.
If you need to order more than one bolt, change the quantity box in your shopping cart to desired quantity. Keep an extra on hand just in case!
