Screwdriver Sets: What You Need to Know

Screwdrivers seem simple. Point and turn, right? But the wrong screwdriver damages screws, slips dangerously, and makes every job harder. Here's how to build a proper collection.

Understanding Screw Types

Slotted (Flathead)

The original. Single slot across the head. Still common in electrical work, furniture, and older equipment. Prone to cam-out (slipping) if you don't match the width precisely.

Phillips (PH)

Cross-shaped recess. Designed to cam out at high torque (prevents over-tightening). Most common in general use. Sizes: PH0 (small), PH1, PH2 (most common), PH3 (large).

Pozidriv (PZ)

Similar to Phillips but with additional smaller cross. Doesn't cam out as easily. Very common in European products and construction. Sizes: PZ0, PZ1, PZ2 (most common), PZ3.

Important: Phillips and Pozidriv look similar but aren't interchangeable. Using the wrong one damages screws.

Torx (Star)

Six-pointed star pattern. High torque transfer, low cam-out. Common in automotive, electronics, and modern furniture. Sizes: T10, T15, T20, T25, T30, etc.

Hex (Allen)

Hexagonal recess. Common in furniture assembly, bikes, machinery. Usually used with L-keys but screwdriver versions exist.

Robertson (Square)

Square recess. Popular in North America, especially for decking screws. Excellent torque transfer.

Building Your Set

Essential Starting Point

• Slotted: 3mm, 5.5mm, 6.5mm
• Phillips: PH1, PH2
• Pozidriv: PZ1, PZ2

This covers 90% of household needs.

Full Workshop Set

Add to the above:

• Slotted: 4mm, 8mm
• Phillips: PH0, PH3
• Pozidriv: PZ0, PZ3
• Torx: T10, T15, T20, T25, T30

Specialist Applications

• Precision set - For electronics, glasses, small items
• Insulated set - For electrical work (VDE rated)
• Long reach - For deep recesses
• Stubby - For tight spaces

Quality Indicators

Tip Hardness

The tip should be harder than the screws you're driving. Soft tips round off quickly. Quality screwdrivers use hardened steel tips.

Tip Accuracy

The tip should fit the screw recess precisely. Sloppy tolerances mean slipping and damaged screws.

Handle

• Comfortable grip for extended use
• Won't roll off the bench (flat sides or hex shape)
• Durable material that withstands solvents

Shaft

• Chrome vanadium steel is standard
• Some shafts are magnetised (helpful but not essential)
• Round shafts allow spinning; hex shafts allow wrench assist

Buying Sets vs Individual

Sets

More economical for building a collection. Usually include a case for organisation. Good for starting out.

Individual

Better for replacing worn tools or adding specific sizes. Often higher quality at the same price point.

Our Advice

Start with a quality set covering the basics. Add individual specialty drivers as needed. Replace worn drivers from the set with quality individuals over time.

Using Screwdrivers Properly

• Match driver size to screw exactly
• Keep the driver aligned with the screw
• Apply downward pressure while turning
• Don't use screwdrivers as pry bars or chisels
• Replace drivers with worn tips

Power vs Manual

Impact drivers and powered screwdrivers are faster for volume work. But manual screwdrivers offer:

• Precise torque control
• Access to tight spaces
• No battery to charge
• Quiet operation

You need both. Power for production, manual for precision and access.
