Description
Sunex Tools 37-Piece 3/8″ Drive Bit Socket Set in EVA Foam (9737) is a comprehensive solution for technicians and mechanics who require a wide range of bit styles for manual fastening applications. This set bridges the gap between standard sockets and specialized drivers by providing a 3/8-inch drive interface for Hex, Torx, Tamperproof Torx, and traditional screwdriver bits. Each component is engineered to provide a precise fit, ensuring that fasteners are turned without damage to the head or the tool.
Key Features and Benefits:
- Comprehensive Variety: This set covers a broad spectrum of fastening needs with 37 different bit sockets, including SAE and Metric Hex, Torx, Tamperproof Torx, Phillips, Pozidriv, and Slotted heads.
- Quality Construction: The bits are manufactured from S2 steel and treated with a manganese phosphate finish. This construction provides the hardness required for high-torque tasks while maintaining the precision of the bitÕs geometry.
- Organized Excellence: The set is housed in a professional EVA foam storage tray. This high-density material ensures that each tool has a dedicated, labeled spot, allowing for instant identification of missing items and keeping the tools from shifting during transport or drawer movement.
- Durability Assured: Every socket base is made from full polish chrome that has been heat-treated. These components meet or exceed ASME and ANSI specifications, ensuring that the tool performs reliably under standard professional use.
- Precision Fit: By adhering to strict manufacturing tolerances, the S2 steel bits provide a seamless engagement with fasteners, reducing the likelihood of “cam-out” or stripping.

How to Use:
- Identify Fastener: Determine the type (Hex, Torx, Phillips, etc.) and size of the fastener you need to remove or install.
- Select Socket: Locate the corresponding bit socket in the EVA foam tray using the engraved size markings for accuracy.
- Attach to Drive: Press the square drive end of the bit socket onto a 3/8-inch drive manual ratchet, breaker bar, or extension until it clicks into place.
- Engage Fastener: Fully insert the bit into the fastener head, ensuring it is seated deeply and squarely to prevent slipping.
- Apply Torque: Rotate the tool to tighten or loosen the fastener, ensuring the tool remains perpendicular to the fastener throughout the process.
- Return to Tray: Once the task is complete, remove the socket from the drive tool and place it back into its designated slot in the EVA foam tray to maintain organization.
Benefits of Using Sunex Tools 37-Piece 3/8″ Drive Bit Socket Set in EVA Foam (9737):
- Correct Specialized Driver: Ensures you have the right driver for almost any light-to-medium duty mechanical task.
- Tamperproof Torx Bits: Allows for work on modern electronics and vehicle components that standard sets cannot service.
- Longer Edge Retention: S2 steel bits maintain their sharp edges longer, providing better grip on shallow or worn fasteners.
- Permanent Drawer Organizer: The EVA foam tray acts as a permanent drawer organizer, saving time spent searching for loose tools and protecting bits from environmental damage.
Features:
- Manganese Phosphate Coating: Provides surface protection and resists oxidation on all bits.
- Engraved Size Markings: Found on every socket base for fast identification in low-light environments.
- High-Density EVA Foam Tray: Designed to fit into standard tool chest drawers and to ensure organized tool storage.
- Portable Tray Configuration: Allows the entire set to be moved to the workspace easily.
- Heat-Treated Socket Bases: Designed to withstand consistent manual torque application.
- S2 Steel Bit Composition: Specifically chosen for its balance of hardness and strength.
- Specialized Sizes: Includes Pozidriv and Tamperproof Torx sizes often missing from standard bit kits.
