Choosing the right screwdriver sounds simple — until you’re standing in front of a screw head you’ve never seen before, or you’re stripping screws because the bit doesn’t fit properly.
In this guide, I’ll walk you through everything you need to know to choose the correct screwdriver for any job around the home or workshop.
This guide pairs perfectly with my Screwdriver Types and Sizes Explained article.
1. Match the Screwdriver to the Screw Head
This is the most important rule: The tip must match the screw head exactly.
Here are the most common types you’ll see in the UK:
- Phillips (PH) — cross‑shaped, common in furniture and appliances
- Pozidriv (PZ) — similar to Phillips but with extra lines; very common in UK wood screws
- Flathead / Slotted — single straight slot
- Torx (T) — star‑shaped, used in cars, electronics, and modern tools
- Hex / Allen — hexagonal, common in flat‑pack furniture
- Precision screwdrivers — tiny versions for electronics, glasses, watches
If the tip doesn’t fit perfectly, you’ll strip the screw or damage the bit.
2. PH vs PZ — The UK’s Most Common Mistake
Most beginners don’t know the difference between Phillips (PH) and Pozidriv (PZ).
Here’s the simple rule:
- PH screws have a plain cross
- PZ screws have a cross plus four faint extra lines
Philips screw (PH)
Pozidriv screw (PZ)
Using PH on PZ (or vice‑versa) causes:
- cam‑out
- stripped screws
- damaged bits
If you want a full breakdown, see my Phillips vs Pozidriv Guide.
3. Choose the Right Size
Each screwdriver type comes in multiple sizes.
For example:
- PH0, PH1, PH2, PH3
- PZ0, PZ1, PZ2, PZ3
- Torx T5, T10, T15, T20, T25
The most common UK sizes:
- PH2 / PZ2 → standard wood screws
- PH1 / PZ1 → smaller screws
- PH0 / PZ0 → tiny screws
- T20 / T25 → DIY and automotive
- T5–T10 → electronics
If the tip wobbles or doesn’t sit fully into the screw, it’s the wrong size.
4. Choose the Right Handle
Different jobs need different handles.
✔ Standard handle
Good all‑rounder for most DIY tasks.
✔ Ergonomic / soft‑grip handle
More comfortable for long jobs.
✔ Insulated (VDE) handle
For electrical work — rated to 1,000V. Never work on electrics without proper VDE tools.
✔ Precision handle
Thin, rotating cap for electronics and small screws.
✔ Stubby handle
For tight spaces where a full‑size screwdriver won’t fit.
5. Choose the Right Shaft Length
Shorter shafts = more control Longer shafts = better reach
Use:
- Short shaft for tight spaces
- Medium shaft for general DIY
- Long shaft for deep or recessed screws
6. Magnetised vs Non‑Magnetised
Magnetised screwdrivers make life easier:
- hold screws in place
- prevent dropping
- ideal for overhead work
Most modern sets include magnetised tips.
7. When to Use a Multi‑Bit Screwdriver
A multi‑bit screwdriver is ideal if you want:
- one handle
- multiple interchangeable bits
- compact storage
They’re perfect for:
- homeowners
- beginners
- flat‑pack furniture
- general repairs
But for heavy use, a dedicated screwdriver is stronger and more comfortable.
8. When You Need a Precision Screwdriver
Use precision screwdrivers for:
- electronics
- laptops
- phones
- glasses
- watches
- small appliances
These sets often include:
- Torx
- Tri‑wing
- Pentalobe
- Micro Phillips
- Micro flathead

9. When to Use a Ratcheting Screwdriver
A ratcheting screwdriver lets you:
- turn screws faster
- keep constant pressure
- avoid repositioning your hand
They’re great for:
- repetitive jobs
- assembling furniture
- working in awkward angles
10. Build a Simple Screwdriver Kit (Beginner Setup)
Here’s a perfect starter kit for UK homeowners:
- PZ2 (most common UK screw)
- PZ1
- PH2
- PH1
- Flathead 5.5mm
- Flathead 3mm
- Torx T20
- Precision PH00 + Flathead 2mm
- Multi‑bit screwdriver
- VDE screwdriver (if doing electrics)
This covers 95% of household tasks.
Common Mistakes to Avoid
- Using PH on PZ screws
- Using the wrong size
- Using a flathead on a Phillips screw
- Using a screwdriver as a pry bar
- Using non‑insulated tools on electrics
- Not pushing firmly enough (causes cam‑out)
