Jargon Buster

• VDE Insulated: Screwdrivers tested and certified to meet German VDE standards for safe use on live electrical equipment up to 1,000 volts. Essential for electricians and anyone working with 240v mains circuits or industrial electrical systems.
• Through-Blade: A design where the metal shaft runs completely through the handle, allowing the tool to be struck with a hammer for additional torque or when dealing with seized fasteners without damaging the screwdriver.
• Cam-Out: The unwanted slipping of a screwdriver from a screw head, typically caused by excessive force, worn tips, or poor engagement. Quality screwdrivers with precisely machined tips minimise this issue.
• PZ vs PH: Pozidriv (PZ) and Phillips (PH) are different cross-head designs often confused. Pozidriv features additional radial lines between the main cross and requires matching drivers to prevent damage and cam-out.
• Torque Rating: The maximum rotational force a screwdriver can handle, particularly relevant for ratchet models and when using screwdrivers with impact tools or extended leverage.
• ERGO Design: Scientifically developed ergonomic handles that optimise force transmission whilst minimising strain on hands and wrists during prolonged use, commonly featured in professional-grade tools.

How to Choose the Right Screwdrivers

Selecting appropriate screwdrivers depends on several key factors:

Intended Application: Consider whether you need insulated VDE screwdrivers for electrical work, precision sets for electronics, or general-purpose tools for everyday tasks. Electricians must always use properly certified VDE tools when working with 240v systems, whilst mechanics benefit from through-blade models that can withstand hammer strikes.

Head Types Required: Identify which fastener types you encounter most frequently. Common options include slotted, Phillips (PH), Pozidriv (PZ), Torx, hex, and specialist security bits. Professional sets from Bahco and Wera typically include the most frequently used profiles, whilst comprehensive kits may contain twenty or more variations.

Handle Design: Ergonomic handles significantly reduce fatigue during extended use. Multi-component grips combine hard and soft materials for optimal comfort and torque transmission. The Bahco ERGO range exemplifies scientifically developed handles that improve productivity whilst reducing repetitive strain injuries.

Quality and Durability: Professional-grade screwdrivers feature hardened, chrome-plated blades that resist wear and corrosion far better than budget alternatives. Black oxide tips provide superior grip within screw heads, preventing cam-out and reducing fastener damage. For trade use, investing in premium brands like Bahco, Wera, or Wiha proves economical over time.

Set or Individual Tools: Beginners and those building toolkits often benefit from comprehensive screwdriver sets that provide commonly needed sizes and types. Experienced tradespeople typically supplement core sets with specific individual drivers as their work demands. Sets available at Tooled-Up range from compact 5-piece collections to extensive 36-piece ratchet systems with interchangeable bits.

Safety Information

When using screwdrivers, particularly in professional environments, observe these essential safety practices:

Electrical Work: Always use properly certified VDE insulated screwdrivers when working on or near live electrical equipment. Standard screwdrivers provide no protection against electric shock from 240v mains circuits. Verify voltage ratings meet BS EN 60900 standards and inspect insulation for damage before each use. Never assume circuits are dead—always test with an approved voltage detector.

Tool Condition: Regularly inspect screwdriver tips for wear, mushrooming, or damage. Worn tips increase cam-out risk, potentially causing hand injuries or fastener damage. Damaged insulation on VDE tools compromises safety and requires immediate tool replacement. Check handles for cracks that could cause grip failure during use.

Proper Technique: Always select the correct size and type of screwdriver for each fastener. Using undersized or mismatched drivers causes cam-out and can result in hand injuries if the tool slips. Position your body to avoid injury should the screwdriver slip, and never hold work in your hand whilst driving screws towards your palm. When additional force is required, use tools specifically designed for striking rather than improvising with standard screwdrivers.

Frequently Asked Questions

What's the difference between Phillips and Pozidriv screwdrivers?

Phillips (PH) and Pozidriv (PZ) are distinct cross-head designs that are not interchangeable. Pozidriv screws feature additional radial lines between the main cross arms and require matching PZ drivers. Using a Phillips driver on Pozidriv screws (or vice versa) causes cam-out, damages fasteners, and can strip screw heads. Always match the driver type to the screw for optimal performance and to prevent damage.

Do I really need VDE insulated screwdrivers for electrical work?

Yes, absolutely. VDE insulated screwdrivers are essential safety equipment when working on or near live electrical circuits up to 1,000 volts. Standard screwdrivers offer no protection against electric shock from 240v mains electricity, which can be fatal. HSE regulations require appropriate insulated tools for electrical work. VDE certification ensures the insulation has been individually tested and meets BS EN 60900 standards, providing verified protection that budget "insulated" tools may not deliver.

How do I know what size screwdriver I need?

Screwdriver sizes are typically designated by tip width for slotted drivers (e.g., 5.5mm) and by point size for cross-heads (e.g., PZ2, PH1). The driver should fit snugly in the screw head without excessive play. For slotted screws, the blade width should match the slot length, whilst the blade thickness should nearly fill the slot depth. Cross-head drivers should seat fully into the recess. Comprehensive sets from brands like Bahco include the most commonly needed sizes for general trade work.

Are ratchet screwdrivers worth buying?

Ratchet screwdrivers significantly improve productivity when driving or removing multiple fasteners, as they eliminate the need to reposition your grip between turns. They're particularly valuable for assembly work, cabinetry, and maintenance tasks involving numerous screws. Quality ratchet mechanisms from professional brands provide reliable operation and typically include multiple bits for versatility. However, they're generally bulkier than standard screwdrivers and may not fit in confined spaces where fixed-blade models are necessary.

How should I maintain my screwdrivers?

Keep screwdriver tips clean and free from paint or debris that could affect engagement with fasteners. Store tools properly to prevent damage to tips and handles—tool rolls or dedicated storage racks work well. Periodically inspect VDE insulated screwdrivers for any damage to the insulation layer, as this compromises electrical safety. Avoid using screwdrivers as pry bars or chisels, which damages tips and handles. For through-blade models, only strike with appropriate hammers and inspect regularly for mushrooming at the striking end, which creates sharp metal fragments.
