How to use

Select the hex key size that matches the fastener head to avoid slippage. Insert the short or long end into the fastener and apply steady, controlled torque; for higher torque use the longer arm for greater leverage. Keep the hex profile fully engaged in the fastener before turning and inspect the tool periodically for wear. Follow package instructions for size identification and any safety notes.
