1. DEWALT DWST17820 Tough System Tool Box: Best Overall
The DEWALT DWST17820 Tuff System Tool Box is our top pick for its rugged build and modular versatility. We researched its IP65 rating and owner feedback confirms it keeps tools dry even in heavy rain. The metal latches and padlock eye add security, and the box stacks neatly with other Tuff System components. However, it lacks a removable tray for organizing smaller items like screws or bits.
Who should skip it: If you need a lightweight, portable box for quick roadside use, this is overbuilt. It’s best for those who already own Tuff System boxes or need heavy-duty protection in a truck bed or garage.
- Heavy-duty resin construction with IP65 dust and water resistance
- Secure metal latches and padlock eye for safety
- Modular design stacks with other Tough System boxes
Pros: Extremely durable, survives drops and weather; Large capacity holds full socket sets and power tools
Cons: Heavier than plastic-only boxes when full; No built-in tray for small parts
2. Stanley STST14027 20-Inch Tool Box: Best Value
The Stanley STST14027 offers excellent value for a basic car tool box. We compared its price to similar models and found it delivers solid durability with a reinforced plastic shell and a removable tray. Owner feedback highlights its lightweight design and the convenience of the tote tray. However, it is not fully waterproof, and the metal latch may wear with heavy use.
Who should skip it: If you need watertight storage or plan to carry heavy power tools, look for a more rugged option. This is ideal for a basic roadside kit or as a secondary organizer.
- Durable polypropylene shell with reinforced corners
- Removable tote tray for small parts
- Metal latch with padlock eye
Pros: Very affordable without sacrificing quality; Lightweight and easy to carry
Cons: Not waterproof, only splash resistant; Latch can feel flimsy over time
3. Plano 135500 4-By-2-By-1.5-Feet Stowaway: Best for Organizing
The Plano 135500 Stowaway is perfect for organizing small car tools and accessories. We evaluated its adjustable divider system and clear lid that allows you to see everything at a glance. Owner feedback praises its lightweight and portable design, ideal for keeping in a glove box or under a seat. However, it is not meant for heavy tools, and the hinges can break if overloaded.
Who should skip it: If you need a box for wrenches, pliers, or larger items, this is too small. It’s best for organizing screws, fuses, and small hand tools.
- Customizable compartments with 4 removable dividers
- Transparent lid for quick identification
- Rust-proof polypropylene construction
Pros: Excellent for small parts like sockets and bits; Easy to see contents without opening
Cons: Too small for full-size tools; Lid hinges are not very robust
4. Craftsman 20-Inch Tool Box (CMST18020): Best for Durability
The Craftsman CMST18020 is built like a tank, with steel reinforcement and ball bearing slides that we found impressive on spec sheets. Owner feedback confirms it holds up well under heavy use, making it a favorite for mechanics. However, its weight is a drawback for portability, and the drawer can get grimy if used in dusty environments.
Who should skip it: If you need a lightweight box to carry around, this is not ideal. It’s best for stationary use in a garage or truck bed.
- Steel-reinforced corners and base for high strength
- Ball bearing drawer slides for smooth operation
- Removable tote tray and padlock eye
Pros: Exceptional build quality, can withstand heavy loads; Smooth drawer action even when full
Cons: Heavier than most plastic boxes; Drawer may collect dirt and debris
5. GearWrench 20-Inch Tool Box (83020): Best for Professionals
The GearWrench 83020 is designed for professionals who want a neat, organized setup. We compared its foam insert to other solutions and found it prevents tools from rattling. Owner feedback from mechanics praises the lockable latches. However, the foam is not customizable, so you may need to cut it for odd-shaped tools, and the cost is higher than similar boxes.
Who should skip it: If you prefer to arrange tools freely or have a mixed set, this may be too restrictive. Best for those with a standard set of wrenches and sockets.
- Includes pre-cut foam insert for tool organization
- Metal latches with key lock
- High-impact polypropylene shell
Pros: Foam insert keeps tools secure and quiet; Lockable for security
Cons: Foam limits customization for non-standard tools; Higher price point for similar capacity
6. Husky 20-Inch Tool Box (HTB20TB): Best Lightweight
The Husky HTB20TB is a lightweight option that we found suitable for basic roadside emergencies. Its low weight and slim design make it easy to stash in any car. Owner feedback notes it works fine for a small socket set and screwdrivers, but the plastic latch and thin walls are not built for abuse.
Who should skip it: If you plan to carry heavy tools or need long-term durability, choose a sturdier box. This is best for minimalists or as a spare.
- Lightweight polypropylene at under 4 pounds
- Integrated handle and removable tote tray
- Low profile fits in tight trunks
Pros: Very easy to carry and store; Good for basic tool sets
Cons: Not very durable; can crack under heavy load; Latch is plastic and prone to breaking
7. Keter 20-Inch Tool Box (240930): Best Weather-Resistant
The Keter 240930 offers decent weather resistance with a UV-stable resin and rubber seal. We evaluated its ability to keep tools dry in rain, and owner feedback generally agrees it works well for light exposure. However, the latch mechanism is finicky, and the box feels less robust than DEWALT or Craftsman options.
Who should skip it: If you need a lockable or heavy-duty box, look elsewhere. This is fine for storing tools in a covered truck bed or garage.
- UV-resistant resin prevents sun damage
- Rubber gasket seals out dust and moisture
- Stackable design with interlocking top
Pros: Good weather protection for outdoor storage; Lightweight compared to metal boxes
Cons: Latch can be difficult to close securely; Not as sturdy as premium resin boxes
Frequently Asked Questions
What size tool box is best for a car?
For most cars, a 20-inch tool box strikes a good balance between capacity and portability. It can hold a basic socket set, wrenches, screwdrivers, and pliers without taking up too much trunk space. If you have a smaller car, consider a 16-inch box or a compact organizer like the Plano Stowaway.
Should I choose plastic or metal tool box?
Plastic boxes are lighter, rust-proof, and often cheaper, making them ideal for car use. Metal boxes are more durable and secure but heavier and prone to rust. For a car tool box, we recommend high-impact plastic like polypropylene or resin, which offers good durability without the weight.
How do I keep my tools organized in a tool box?
Look for boxes with removable tote trays, adjustable dividers, or foam inserts. The Stanley STST14027 and Plano Stowaway are great for organization. You can also use small parts bins or magnetic strips to keep sockets and bits from rattling.
Are lockable tool boxes worth it?
If you store tools in a shared garage or truck bed, a lockable box adds security. Models like the DEWALT DWST17820 and GearWrench 83020 have padlock eyes or built-in locks. For a trunk, a lock may not be necessary, but it can prevent tools from spilling if the box tips over.
Can I use a tool box for other car accessories?
Yes, tool boxes are versatile for storing jumper cables, tire repair kits, flashlights, and emergency supplies. Just ensure the box is large enough and has compartments to keep items from shifting. A box with a removable tray is especially handy for separating small accessories.
Our Verdict
After researching and comparing specs, owner feedback, and safety standards, our top pick is the DEWALT DWST17820 Tuff System Tool Box for its superior durability, weather resistance, and modular design. For a more budget-friendly option, the Stanley STST14027 offers great value and organization. Choose based on your need for portability, capacity, and weather protection.
