I have a 1/4 Snap On flex head ratchet (TF936)
I rounded off the torx screw on the flex joint, I used a extractor to remove the rounded off bolt, Threads looks good, ran a tap, to clean them,
What size is the bolt, and does Snap On carry this part?
The best part of this ratchet, it costed me 15 bucks at the swap meet
