How to use

Select the appropriate drive size (1/2" or 1/4") and the matching socket or bit for the fastener. Attach the socket or bit to the ratchet, T-handle or extension as required. Use the universal joint or flexible extension to access angled or recessed fasteners. Store tools back in their designated slots in the case after use to maintain organization and protect the set.

Usage recommendations

For safe and long-lasting performance, use appropriate torque for each fastener, avoid exposing tools to corrosive environments, and keep the case closed during transport. Regularly clean and lightly oil moving parts of ratchets to maintain smooth operation.
