Setup and Assembly
The WORKPRO 42-Piece Socket Set comes pre-assembled and organized in its storage case. No complex assembly is required. Simply open the case and select the desired tool.
- Identify Components: Familiarize yourself with the different sockets, bits, the stubby ratchet, and the quick-release bit holder as laid out in the case.
- Selecting a Socket: For using sockets, ensure the ratchet is set to the 1/4" square drive side. Press the socket onto the square drive until it clicks securely into place.
- Selecting a Bit: For using screwdriver bits, ensure the ratchet is set to the 1/4" hex drive side. Insert the desired bit into the quick-release bit holder. Pull back the blue collar on the bit holder to insert or remove bits. Release the collar to lock the bit in place.
- Attaching Bit Holder to Ratchet: The quick-release bit holder can be inserted directly into the 1/4" hex drive of the stubby ratchet.

Instructions for using the magnetic quick-change bit holder: pull collar back to release/change bits. Note: bits are not magnetized and require a magnetizer.
Operating Instructions
- Select the Correct Tool: Choose the appropriate socket or screwdriver bit for the fastener you are working with. Ensure a snug fit to prevent stripping.
- Attach to Ratchet: Securely attach the chosen socket or bit (via the quick-release holder) to the 1/4" drive of the stubby ratchet.
- Set Ratchet Direction: Use the forward/reverse switch on the ratchet head to select the desired direction for tightening or loosening. The switch moves smoothly for easy direction change.
- Apply Force: Place the tool onto the fastener. Apply steady, even pressure while rotating the ratchet handle. The 72-tooth mechanism and 5-degree swing arc allow for effective use in confined spaces.
- Working in Tight Spaces: The stubby design (120mm length) and small swing arc make this ratchet ideal for areas with limited clearance.

Various applications of the WORKPRO socket and bit set, including automotive repair (engine components) and household tasks (furniture assembly, bicycle maintenance).
Maintenance
- Cleaning: After each use, wipe down all tools with a clean, dry cloth to remove dirt, grease, and debris. For stubborn grime, a mild degreaser can be used, followed by thorough drying.
- Lubrication: Periodically apply a small amount of light machine oil to the ratchet mechanism to ensure smooth operation and prevent corrosion.
- Storage: Always store the tools in their original clear-top storage case. This protects them from damage, keeps them organized, and prevents loss. Store in a dry environment to prevent rust.
- Inspection: Regularly inspect tools for any signs of wear, damage, or corrosion. Replace any damaged components immediately to ensure safety and performance.
- Rust Resistance: The tools are made of chrome vanadium steel with a bright matte finish to prevent corrosion. Proper cleaning and storage will maintain this protection.
Troubleshooting
- Socket/Bit Not Holding Securely:
- Ensure the socket is fully pushed onto the ratchet's square drive until it clicks.
- For bits, ensure the quick-release collar is fully released after inserting the bit. Check for any debris obstructing the locking mechanism.
- Ratchet Mechanism Sticking/Rough:
- The ratchet mechanism may be dirty or dry. Clean the ratchet head thoroughly and apply a small amount of light machine oil to the moving parts.
- Bits Not Magnetic:
- The screwdriver bits themselves are not inherently magnetized. If magnetic retention is desired, use a separate magnetizer tool on the bits. The quick-release bit holder provides mechanical retention.
- Difficulty in Tightening/Loosening:
- Ensure you are using the correct size socket or bit for the fastener.
- Verify the ratchet direction switch is set correctly (forward for tightening, reverse for loosening).
User Tips
- Maximize Tight Space Access: The stubby ratchet's compact size and 5-degree swing arc are specifically designed for confined areas. Don't hesitate to use it in situations where a standard ratchet would be too large.
- Secure Bit Changes: Always pull the blue collar of the quick-release bit holder fully back when inserting or removing bits to ensure a secure lock and prevent bits from falling out during use.
- Organized Storage: Utilize the clear-top storage case to keep all 42 pieces organized. The clear lid allows for quick identification of tools, saving time during tasks.
- Versatile Applications: This set is not just for auto repair. Its precision and variety of bits make it excellent for electronics, furniture assembly, bicycle maintenance, and other household repairs.
