10 Tools Mechanics Swear By (And 5 That Are Total Garbage)
As a former automotive technician, I can tell you that tools are expensive. I had a bill with SnapOn for years before I decided to leave the trade. That said, not every tool is created equal. There are some tools that mechanics swear by, and others they know are complete garbage (from experience). To save you the trouble, here’s a list of 10 tools mechanics swear by, and 5 you should probably avoid altogether.
1. Torque Wrench
The power of a good torque wrench cannot be overstated. It’s one of the best tools for mechanics because it ensures bolts are tightened to the correct specifications. Over-tightening can damage parts, while under-tightening can lead to dangerous failures. This tool is indispensable when working on engines, wheels, and suspension systems. Digital versions offer even more precision, giving pros the accuracy they need. Every serious mechanic owns at least one, and it’s not hard to see why.
2. Impact Wrench
When you’re dealing with stubborn bolts, an impact wrench saves time and your knuckles. Mechanics love this tool because it delivers high torque with minimal effort. Whether air-powered or cordless, these tools make short work of tire changes and suspension repairs. They’re far more efficient than a traditional ratchet. Once you’ve used an impact wrench, there’s no going back.
3. OBD2 Scanner
Modern cars are packed with sensors, and when something goes wrong, the best tools for mechanics include a reliable OBD2 scanner. These devices read diagnostic trouble codes from your car’s onboard computer. It’s a quick way to pinpoint issues without endless guesswork. Some high-end scanners also offer live data and freeze-frame capabilities. Mechanics rely on this tool to make fast, accurate diagnoses.
4. Pry Bars
Pry bars offer the mechanical leverage needed to separate components without damage. Whether it’s popping a ball joint or separating an exhaust system, this tool comes in handy. Professionals use them daily and often keep a few sizes in their tool chest. They’re simple but incredibly effective. The key is to choose high-strength steel that won’t bend under pressure.
5. Multimeter
A good multimeter is a staple in the toolbox of any mechanic dealing with modern vehicles. From testing batteries to diagnosing wiring faults, it’s a multifunctional tool. It’s especially vital for working on hybrid and electric vehicles. High-end models can also measure temperature and frequency. For those who take electrical diagnostics seriously, this tool is essential.
6. Mechanic’s Creeper
A low-profile rolling creeper allows mechanics to slide under vehicles easily and comfortably. Instead of crawling on cold concrete, you’re rolling on padded support. It’s a simple tool, but one of the best tools for mechanics who work in garages without lifts. The right creeper can reduce strain and fatigue during long jobs. Bonus points for ones with adjustable headrests or built-in trays.
7. Magnetic Parts Tray
There’s nothing worse than losing a bolt in the engine bay. Magnetic parts trays help mechanics keep small items organized during disassembly. They’re especially useful during brake jobs, engine work, or electrical repairs. These trays cling to metal surfaces and hold everything from nuts to fuses. They may be simple, but they’re a lifesaver.
8. Ratcheting Wrenches
Ratcheting wrenches allow you to work in tight areas where a full swing of a wrench isn’t possible. Mechanics love these for their speed and efficiency. They eliminate the need to constantly reposition the wrench. Flex-head models offer even more versatility in awkward spots. These tools combine the best of both worlds—speed and access.
9. Work Light
No matter how experienced you are, you can’t fix what you can’t see. A powerful, rechargeable work light is among the best tools for mechanics for tackling dark engine bays or undercarriage areas. LED models are preferred for their brightness and low heat. Adjustable stands and magnetic bases add to their functionality. Good lighting can make the difference between a successful repair and a missed issue.
10. Shop Vacuum
After a big job, a shop vacuum quickly clears out dust, debris, and metal shavings. Mechanics appreciate this tool not just for cleanup, but also for catching dropped parts in hard-to-reach areas. Wet/dry vacuums offer more versatility in the garage. It’s a maintenance essential that too many DIYers overlook. A clean workspace is a safer workspace.
What Are 5 Tools That Mechanics Say to Avoid?
1. Cheap Socket Sets
Inexpensive socket sets often strip, crack, or break under pressure. Mechanics avoid them because they end up causing more damage than they fix. When working on tough bolts, quality matters. Stick with reputable brands with forged steel construction. Bargain-bin tools just won’t hold up to daily use.
2. Gimmicky Multi-Tools
Those flashy “18-in-1” mechanic tools often look cool but lack the durability or precision needed. They’re more suited to glove box emergencies than serious garage work. Most mechanics say they collect dust after a single use. A dedicated tool will always outperform a jack-of-all-trades gadget. Save your money for tools that actually last.
3. No-Name Impact Wrenches
Off-brand impact wrenches may look like a steal online, but most lack the torque and battery life needed for real jobs. Mechanics report frequent motor failures and stripped internals. Performance just doesn’t compare to professional-grade tools. It’s one tool you don’t want to cheap out on. You’ll end up buying twice.
4. Plastic Creepers
While cheaper than padded models, plastic creepers tend to crack easily and offer poor support. Mechanics complain about back strain and durability issues. Once cracked, they’re unsafe to use. Investing in a high-quality padded creeper pays off in the long run. Comfort matters when you’re under a car for hours.
5. Disposable Nitrile Gloves
While I did use nitrile gloves when I worked on cars, they tore constantly. Many mechanics prefer heavy-duty alternatives or reusable options. When working with sharp edges, fluids, or hot surfaces, protection is crucial. These disposable gloves just don’t offer enough reliability. If you’re serious about your hands, gear up properly.
What You Use Says a Lot About How You Work
Don’t become blindly loyal to any one brand. You need to do your research and pick out the equipment that will truly allow you to do your job to the best of your ability. Whether you are just a weekend warrior or a budding professional mechanic, this list gives you an idea of what you’ll actually need in your toolbox (and what you should skip over when the SnapOn truck rides through). At the end of the day, a mechanic is only as good as the wrench on his belt.
