Check Your Thread: Make sure your drill chuck adapter requires a Left-Hand Thread (Reverse Thread) screw.2. Turn Anti-Clockwise to Tighten: Remember, since this is a reverse screw, you must turn it counter-clockwise (leftward) to tighten it into the shank adapter. Turning it clockwise will loosen it.3. Secure Firmly: Insert the screw through the center of the drill chuck opening and tighten it securely with a standard Phillips screwdriver.________________________________________📦 PACKAGE OPTIONS (Choose Your Kit)• 5 PCS / Pack – Perfect for quick DIY home repairs.• 10 PCS / Pack – Best value for local repair shops and craftsmen.• 20 PCS / Pack – Bulk option for industrial workshops and heavy users.• Mixed Assortment Packs are also available in the SKU options!
