1. Introduction
This manual provides essential information for the safe and effective use of your DURATECH 4-in-1 Flex-Head Reversible Ratcheting Box Wrench Set. Please read these instructions thoroughly before operating the tools and retain this manual for future reference. This set includes two metric wrenches designed for versatility and efficiency in various fastening tasks.
2. Product Overview
The DURATECH 4-in-1 Flex-Head Reversible Ratcheting Box Wrench Set is engineered for durability and ease of use. Each wrench features a 4-in-1 design, providing multiple sizes on a single tool, and a flexible, reversible ratcheting head for improved access and speed.
Key Features:
- Quality Construction: Made from premium chrome vanadium steel with a mirror polish finish, chrome plated for rust resistance, heat-treated for maximum strength, and drop-forged for a long lifespan.
- 4-in-1 Design: Each wrench offers four sizes, reducing the number of tools required. Sizes are clearly stamped on both sides of the handle for easy identification. The metric set includes 8mm, 10mm, 12mm, 13mm, 16mm, 17mm, 18mm, and 19mm.
- 72-Tooth Ratcheting Mechanism: Requires only a 5-degree working swing arc, ideal for tight spaces. The 12-point box end ensures quick engagement with fasteners and helps prevent rounding off.
- Reversible Flex-Head: A quick reversing lever allows for continuous engagement with the fastener. The flush-mounted lever enables direction changes without removing the wrench. The flex-head pivots 180 degrees, holding any angle for optimal access around obstructions.
- Convenient Storage: Includes a rolling pouch with printed wrench sizes for organized storage and easy transport.

3. Setup
The DURATECH wrench set requires minimal setup. Upon receiving the product, remove the wrenches from their packaging. The included rolling pouch is designed for organized storage and easy access.
Using the Storage Pouch:
- Unroll the pouch to reveal the individual slots for each wrench.
- Place each wrench into its designated slot, matching the wrench sizes to the labels printed on the pouch.
- To secure, roll the pouch tightly and fasten the black plastic buckle. The two lanyards can be used for hanging the pouch if desired.

4. Operating Instructions
These wrenches are designed for efficient tightening and loosening of fasteners in various applications.
4.1 Selecting the Correct Size
Identify the required fastener size. Each wrench has four sizes stamped on its handle. Select the end of the wrench that matches the fastener size.
4.2 Engaging the Fastener
Position the 12-point box end of the wrench over the fastener. The 12-point design allows for quick engagement from multiple angles.
4.3 Using the Ratcheting Mechanism
Once engaged, apply force to the wrench handle to turn the fastener. The 72-tooth ratcheting gear requires only a 5-degree swing arc, allowing for continuous turning without removing and repositioning the wrench, especially in confined spaces.

4.4 Utilizing the Flex-Head
The flex-head can pivot up to 180 degrees. Adjust the head to the desired angle to navigate around obstructions or to achieve a more comfortable working position. The head will hold its angle during use.
4.5 Reversing Direction
To change the direction of the ratcheting action (from tightening to loosening, or vice-versa), use the flush-mounted reversing lever located on the head of the wrench. Simply push the lever to the opposite side. This can be done without removing the wrench from the fastener.

4.6 General Usage Tips
- Always ensure the wrench head is fully seated on the fastener to prevent slippage and damage to both the fastener and the tool.
- Avoid using extension pipes or excessive force, as this can damage the ratcheting mechanism or the wrench itself.
- For stubborn fasteners, apply steady, increasing pressure rather than sudden jerks.

5. Maintenance
Proper maintenance will ensure the longevity and optimal performance of your DURATECH wrenches.
- Cleaning: After each use, wipe the wrenches clean with a dry cloth to remove dirt, grease, and debris. For heavier grime, use a mild degreaser and then wipe dry.
- Rust Prevention: Although chrome plated for rust resistance, prolonged exposure to moisture can still cause corrosion. Store the wrenches in a dry environment, preferably in their rolling pouch. Applying a light coat of rust-inhibiting oil periodically can further protect the tools.
- Lubrication: The ratcheting mechanism and flex-head pivot points may benefit from occasional lubrication with a light machine oil to maintain smooth operation. Apply sparingly and wipe off any excess.
- Inspection: Regularly inspect the wrenches for any signs of wear, damage, or deformation. Discontinue use if any significant damage is observed.
6. Troubleshooting
This section addresses common issues that may arise during the use of your wrenches.
6.1 Flex-Head Becomes Loose
If the flex-head becomes excessively loose and does not hold its position, it may indicate wear or a need for adjustment. Some flex-heads are designed with a tensioning screw (often a Torx screw) that can be carefully tightened. However, overtightening can damage the mechanism. If the issue persists after careful adjustment, or if no adjustment mechanism is apparent, contact customer support.
6.2 Ratcheting Mechanism Malfunction
If the ratcheting mechanism slips, jams, or the reversing lever does not function correctly, inspect for debris or damage. Clean the mechanism thoroughly and apply a small amount of lubricant. If the issue continues, or if the reversing lever appears broken or dislodged, the tool may require professional repair or replacement. Avoid forcing the mechanism, as this can cause further damage.
6.3 Wrench Slipping on Fastener
Ensure you are using the correct size wrench for the fastener. A wrench that is too large will slip and can damage both the fastener and the wrench. Ensure the wrench head is fully seated on the fastener before applying torque. If the wrench continues to slip, the fastener may be stripped, or the wrench head may be worn.
