When tackling household or automotive repairs and projects, the humble screwdriver is one of the most essential tools in any toolbox. However, with so many different types of screwdriver heads and sizes available, it can be difficult to choose the right one for a given task. In this article, we'll break down the different screwdriver types, cover their key features and common applications, and provide tips to help you select the ideal screwdrivers for optimizing your DIY experience.
Considerations for Tool Selection
When dealing with tools that could impact your finances, safety, or property if used incorrectly, it's important to invest the time upfront to choose options designed for their intended use. For projects involving your home, vehicle, or electrical work, using the proper tool can mean the difference between a job done right and potential expensive mistakes. As screwdrivers are one of the most versatile but potentially dangerous hand tools if misused, focusing on quality, fit, and safety features should be top priorities.
Rather than opting for the lowest-cost generic screwdriver, consider mid-range tools from trusted brands. These tend to offer tighter tolerances between head and fastener for better control and less slippage. Comfortable, insulating grips reduce fatigue and risk of shocks. Weight and balance also affect long-term use, so take accessories for a "test drive" if possible. Overall, a minimally more expensive screwdriver could save much greater costs down the road.
Screwdriver Head Types
The head is the most important part of any screwdriver, as it must match the type and size of fasteners being worked on. Here are the common head styles:
Flathead Screwdriver
Characterized by a flat blade, these drive screws with recessed slots like those found in furniture or older appliances/electronics. While less precise than other styles, flatheads work well for rough tasks and have good torque capacity.
Phillips Screwdriver
With a "+" shaped tip, Phillips screwdrivers mate with the most prevalent screw heads today. Numbered sizes (0-3) indicate tip width and fit. Avoid hardware store versions for precision work.
Robertson Screwdriver
A square-recessed design offering torque transmission rivaling Phillips. Found mainly in Canada, they resist camming out better but require special bit holders.
Torx Screwdriver
A 6-point starhead pattern, Torx are highly secure and ideal for electronics/small appliance assembly. T-handles boost mechanical advantage.
Hex/Allen Screwdriver
The six-sided internal head acts like a nut for a hex/Allen wrench. Great for tight spaces and consistent torque transmission.
Slotted Screwdriver
Thin blade mates with straight-line slots, sometimes called a straight-blade screwdriver. Seldom used outside specialized industrial/machining applications.
Additional Screwdriver Features
Beyond head type, other attributes affect versatility and control:
Handles - Comfortable pistol grips allow palm-based manipulation for precision. T-handles provide extra leverage.
Insulated Shafts - Protects users from shocks when working with electrical/metal objects. Look for UL certification.
Magnetic Tips - Conveniently retrieves dropped screws/fasteners, reducing frustration.
Length/Thickness - Long, thin shafts access recessed areas, while shorter, stouter varieties deliver power. Consider multi-piece designs.
Bits - Interchangeable heads like Phillips enable one handle to drive multiple styles. Invest in premium bit sets.
Ergonomics - Non-slip textures, contoured shapes, and balanced weight distribution minimize fatigue on long jobs.
Durability - Tough shaft materials like carbon steel or titanium alloy resist bending/wear over time.
Warranty - Reputable brands back their tools, showing confidence in quality/service lifespans.
Common Screwdriver Applications
Now that the various types and attributes are covered, here are some standard applications for specific screwdriver styles:
Flathead - Furniture assembly, appliances, shipping crates, vintage electronics/machinery.
Phillips - Anything from devices to vehicles to construction uses this ubiquitous head. Precise #1 sizes for electronics/eyeglasses.
Robertson - Throughout Canada for woodworking, durable construction, and vehicle maintenance.
Torx - Small electronics, eyeglasses, devices, firearms. T-15/20 also popular for auto/motorcycle work.
Hex/Allen - Bicycles, machinery, threaded rod/bolts. Hidden/recessed fasteners. Prefers 1.5-6mm.
Slotted - Large pulleys, valves, plumbing/pipe fittings, or wherever parallel sides allow wrench access.

FAQs About Screwdriver Selection
What types of screws do flathead screwdrivers work with?
Flathead screwdrivers are designed to drive slotted screws, which have a straight line recess cut into the head rather than a cross shape. These older style screws can be found securing furniture, older appliances, electronics, shipping crates and similar construction applications.
H3: Why would I choose a magnetic tip screwdriver?
Magnetic tip screwdrivers are extremely handy whenever small screws or fasteners are involved. The magnet embedded in the tip prevents dropped screws from rolling away and saves you time searching for them on the floor. This is especially useful for electronics work or when assembling small devices with miniature parts. The magnetic feature adds just a small amount to the cost but pays for itself in frustration avoided.
What's the difference between Phillips and Pozidriv screwdriver heads?
While Phillips and Pozidriv heads look similar, Pozidriv has a more precise angular point designed to reduce cam-out when tightening screws. This makes Pozidriv better suited for precision assembly tasks. Phillips is considerably more common, so a combination Phillips/Pozidriv style set is optimal to handle both. Always use the narrowest compatible screwdriver to prevent cam-out as well.
How do I choose between standard vs. ergonomic screwdriver handles?
Standard straight handles prioritize leverage over comfort on bigger screwdrivers, and some styles like T-handles increase mechanical advantage further. Ergonomic pistol grips contour to the hand for less strenuous smaller projects and fine control. Choose standard for occasional heavy duty use and ergonomic for prolonged everyday tasks to prevent hand fatigue. Balanced weight is also a factor alongside personal preference.
What's the best way to store and organize screwdrivers?
Some popular storage methods are screwdriver roll-ups, plastic cases with slots, pegboards, magnetic racks/bars, and wall-mounted racks/holders. Rolls and cases keep bits organized portably, while magnetic options free up table/bench space. With any method, group by size/type and clearly label drawers/sections to quickly find the needed style. Consider screw and bit trays/holders as accessories for even easier access and to keep tip profiles sharp.
Summary
To recap, screwdrivers come in various head types to match corresponding screw styles. Features like ergonomic handles, magnetic tips, different lengths and interchangeable bits add versatility. Top brands emphasize comfort, precision, and durability for tasks large and small. Taking time to understand an application's requirements and selecting the properly sized, high-quality screwdriver makes any project more efficient and helps avoid costly mistakes. Proper storage keeps the entire set organized for when inspiration strikes. Armed with this knowledge, homeowners and mechanics alike can feel confident tackling a wide range of repairs and builds.
