Screwdrivers are so basic they get overlooked. Most people use whatever came in a blister pack from the dollar store and wonder why they strip screw heads and shred cam-outs. A quality screwdriver set with the right tip types and sizes eliminates stripped screws, reduces hand fatigue, and handles the fasteners you actually encounter in home repair and workshop projects. Here is what to buy, what to skip, and how to use them properly.

Screwdriver Set Essentials

Tip Types That Matter

Phillips (#1, #2, #3)

Phillips is the most common drive type in North American construction, furniture, and appliances. The #2 Phillips handles roughly 80 percent of all Phillips screws you encounter. A #1 covers smaller screws (electrical outlets, electronics, hinges), and a #3 handles larger construction screws.

The critical detail: Phillips was designed to cam out — the driver slides out of the screw head when torque exceeds a threshold. This was originally a feature for assembly line power driving, but for hand work it means stripped heads. The solution is downward pressure. Push the screwdriver firmly into the screw head while turning. The driver should feel locked in, not skating on top.

Flat (Slotted) — 1/4”, 3/16”, 5/16”

Flat-head screws are rare in new construction but common in older homes, vintage furniture, and electrical work. Electricians use flat-head screwdrivers more than anyone. Terminal screws on outlets, switches, and breaker panels are almost all slotted.

Match the blade width to the screw slot exactly. A blade that is too narrow concentrates force on a small area and damages the slot. A blade that is too wide extends past the screw head and damages the surrounding material.

Robertson (Square Drive) — #1, #2, #3

Robertson is the dominant drive type in Canada and increasingly common in the United States for deck screws, cabinet screws, and construction fasteners. The square recess grips the driver firmly with zero cam-out. Once you use Robertson screws, you understand why Canadians refuse to use Phillips.

Most deck screws from GRK, Spax, and Grip-Rite use #2 Robertson or a combination Robertson/Phillips head. Keep a #2 Robertson in your kit for deck projects and cabinet work.

Torx (Star Drive) — T15, T20, T25

Torx is taking over from Phillips in many applications because it provides superior torque transfer with no cam-out. Automotive, appliance, and furniture fasteners increasingly use Torx. The IKEA Allen key is being replaced by Torx in many newer products.

T20 and T25 are the most common sizes for construction and furniture fasteners. T15 handles smaller screws in electronics and appliances.

Hex (Allen) — 5/64” through 3/8” and metric equivalents

Allen keys come in every toolkit, usually as L-shaped wrenches. A set of hex screwdrivers with proper handles provides better torque and control for furniture assembly, set screws on power tool accessories, and machine adjustments.

What to Actually Buy

The Practical Starter Set

Wera Kraftform Plus 6-piece set ($30 to $40): Includes #1 and #2 Phillips, 4mm and 5.5mm flat, and two sizes you will use constantly. Wera handles are ergonomic and the tips are laser-etched for grip. This is the set that converted me from cheap screwdrivers.

Klein Tools 7-piece Cushion-Grip set ($25 to $35): The electrician’s standard. Includes three flat, three Phillips, and one cabinet tip. Built for daily professional use and nearly indestructible.

Wiha 12-piece set ($40 to $50): German-made precision. Includes Phillips, flat, Torx, and square drive. Excellent tip quality that lasts.

The Budget Option

Stanley 10-piece set ($15 to $20): A decent starter set. The tips are softer than Wera or Wiha and will eventually round off with heavy use, but they work for occasional home repair.

What to Skip

Avoid the 50-piece or 100-piece sets with dozens of obscure specialty bits. You will never use the Triangle, Spanner, or Tri-Wing drivers. They bulk up the set and fill your drawer with tools that come out once a decade. Buy the core sizes in quality and add specialty drivers individually when a specific project demands them.

Driver Quality: Why It Matters

The difference between a $2 screwdriver and a $8 screwdriver is the tip. A quality driver tip is precision-machined to match the screw recess exactly. It fills the recess completely with no slop. This full contact distributes torque evenly and prevents cam-out.

Cheap screwdriver tips are stamped from soft steel, slightly undersized, and round off after moderate use. A rounded Phillips tip spins in the screw head, strips the recess, and turns a simple task into a drill-and-extract operation.

The handle matters too. A good handle fills your palm, provides grip when your hands are oily or sweaty, and transmits torque without hot spots. Wera, Wiha, and Klein all invest in handle design. The Wera Kraftform handle is shaped to fit the natural grip of the human hand — it sounds like marketing, but it genuinely reduces hand fatigue during extended use.

Specialty Screwdrivers Worth Owning

Stubby screwdriver: A 1-inch shaft Phillips and flat head for tight spaces where a full-length driver does not fit. Behind toilet tanks, inside electrical boxes, between framing members.

Offset screwdriver: An L-shaped driver for reaching screws in confined spaces where neither a straight driver nor a drill fits. Cheap ($5) and irreplaceable when you need it.

Precision screwdriver set: Tiny drivers for eyeglasses, electronics, and small hardware. The Wiha 26-piece precision set ($30) handles every small fastener you encounter.

Insulated screwdriver set: For electrical work. VDE-rated insulated screwdrivers protect against accidental contact with live wires up to 1,000 volts. The Wera Kraftform VDE 6-piece ($40) or Wiha Insulated set ($35) are worth the investment if you work on electrical circuits.

Care and Maintenance

Screwdrivers require minimal maintenance but a few habits extend their useful life:

Never use a screwdriver as a pry bar, chisel, or punch. The tip is hardened steel optimized for torque, not impact or leverage. Using it as a pry bar mushrooms the tip and ruins it for its actual purpose.
Regrind rounded tips on a bench grinder. A flat-head tip can be reground to its original profile in 30 seconds. Phillips tips are harder to restore — at that point, buy a replacement.
Keep tips clean. Paint, adhesive, and corrosion on the tip reduce grip. Wipe tips with a rag and a drop of mineral spirits after messy jobs.
Store upright in a drawer organizer or wall rack. Screwdrivers loose in a drawer bang tips against each other and dull them.

Bottom Line

Buy a 6 to 12-piece set from Wera, Wiha, or Klein with #1 and #2 Phillips, two flat heads, and a couple of Torx drivers. Supplement with a Robertson #2 for deck and cabinet work, a stubby set for tight spaces, and insulated drivers for electrical projects. Total investment: $50 to $80 for tools that last 20 years and stop you from stripping every other screw head.
