Hand Tools

The right hand tools make automotive repairs faster, safer, and far less frustrating. Whether you're just getting started or adding to your existing set up, having the proper tools is the foundation of any successful job.

From basic maintenance to more involved repairs, a well-built toolkit helps you work efficiently and avoid damaging parts. Keep reading to learn the main tool categories, what to look for when buying a new hand tool, and how to shop NAPA's full selection.

Sockets, Ratchets, and Torque Wrenches

Sockets, ratchets, and torque wrenches are the backbone of any automotive tool kit, because they're used for removing, installing, and tightening nearly every fastener on a vehicle.

Sockets and ratchets work as a team. The socket fits over the fastener, and the ratchet drives it. Ratchets come in three drive sizes to match the socket and torque requirements for a wide variety of jobs:

• 1/4" for tight spaces and small fasteners
• 3/8" for the most versatility
• 1/2"for heavy-duty work like lug nuts and suspension components

If you work on a variety of vehicles, have both metric and SAE sockets on hand, because Canadian vehicles use both systems. Extensions and universal joints are also helpful for working in hard-to-reach areas.

A torque wrench completes this trio. Where a ratchet removes and helps to install fasteners, a torque wrench ensures safety-critical fasteners, like lug nuts and caliper bolts, are tightened to the manufacturer's specifications.

Sockets and torque wrenches are functional pairs, since you attach a socket to the torque wrench drive to tighten fasteners.

Buying Tips

If you're building your toolkit from scratch, start with a 3/8" drive set. When you're ready to expand, look for sets that include a good range of sizes, rather than buying individual sockets or ratchets.

If you're new to torque wrenches, find a click-style torque wrench, because they're reliable and straightforward to use. For a more experienced DIYer, a digital torque wrench makes a great investment.

Wrenches

Combination Wrenches

Combination wrenches have an open and closed end on opposite sides of the tool. They are the most versatile, everyday wrench. While the closed end provides better torque, the open end fits in tighter spots for hard-to-reach jobs.

Ratcheting Wrenches

This hand tool has the same principle as combination wrenches, but with a built-in ratcheting mechanism that allows you to work faster in cramped engine bays.

Adjustable Wrenches

This convenient tool can be adjusted to fit odd sizes but tends to be less precise. It's better suited as a backup than a primary wrench.

Flare Nut/Line Wrenches

This specialized wrench is for work on brake and fluid lines and is designed to prevent rounding of soft fittings.

Buying Tips

Consider purchasing a set ranging from 8 mm to 19 mm metric, since this'll cover most automotive fasteners. Combination wrench sets offer the best value for DIYers at any skill level, but ratchet wrenches are worth the upgrade if you frequently work in tight spaces.

Screwdrivers and Hex Keys

Screwdrivers are essential for a wide variety of automotive applications, including removing interior panels, sensors, and electrical components. Phillips (#1 and #2 at a minimum), flathead, Torx, and Robertson are all tip types worth having in your kit.

For brake caliper guide pins, set screws, and a wide range of other fastener work, purchase Hex or Allen keys. You can find these in both L-shaped sets and bit-driver formats.

Buying Tips

For a space-saving, starter option, a multi-bit screwdriver with interchangeable tips is a great universal tool. As you expand your toolkit, individual screwdrivers with dedicated tips offer better durability for frequent use.

For Torx bits, putting a T10, T15, T20, T25, T30, and T40 into your toolbox will give you an excellent range to work with. Hex key sets in both metric and SAE are inexpensive and worth having on hand for a wide range of jobs.

Pliers

Pliers are essential for gripping, bending, cutting, and holding components in place while you work. Consider having one of every plier type in your toolbox.

• Needle-nose pliers are ideal for reaching into tight spaces, pulling fuses, and handling small components.
• Locking pliers clamp onto a fastener or part and hold it in place so you can work hands-free.
• Slip-joint pliers are a general-purpose tool for gripping hoses, fittings, and fasteners of various sizes.
• Snap ring pliers (both internal and external styles) are often overlooked, but are essential for suspension, drivetrain, and wheel hub work.

Buying Tips

A starter set including all four plier types will cover most automotive situations. As you advance, adding a few specialty pliers can make specific jobs significantly easier.

Hose clamp pliers are a worthwhile upgrade for cooling system or fuel line work. Upgrading to a heavy-duty combination snap ring plier with interchangeable tips gives you more flexibility across different ring sizes and applications.

Hammers, Mallets, and Pry Bars

Steel hammers are the go-to tool for driving punches, chisels, and working with heavier components. On the other hand, a rubber mallet can help knock stuck components free or seal parts into place without causing damage. They are much safer than a steel hammer on most automotive surfaces.

Pry bars are for leverage work, like pulling away stubborn brake rotors or separating corroded components. They are especially helpful for Canadian drivers, since road salt can cause parts to rust and seize together.

Sets vs. Individual Tools - What Do You Need?

Comprehensive mechanic's sets offer the best value if you're building your toolkit from the ground up. They include sockets, ratchets, extensions, and sometimes wrenches in one organized case.

Buying individual tools is ideal if you're filling gaps in an existing toolkit or buying a specialty tool for a specific job.

Of course, how you store your tools will also keep them in great condition for years to come. Consider purchasing a quality toolbox or tool chest to keep everything organized and protected against dust, debris, and the elements.
