A slotted screwdriver is for screws with a straight slot. The screwdriver must match both the screw-head type and its size.
Typical applications
- Slotted screwdrivers turn matching slotted screws. Do not substitute a straight blade for a Phillips, Torx or other screw head it was not designed to fit.
Advantages
- When using a generic slotted screwdriver, match the screwdriver to the screw head in both size and type. The blade tip width should match the width of the slotted screw head.
Specifications to check
- Check that the blade-tip width matches the slotted screw head and that the tool is the correct type. Select a handle securely attached to its shank.
Limitations
- A generic slotted screwdriver should not be used for prying, punching, or chiseling, because those tasks are outside its screw-driving role.
Buying considerations
Selection advice: check screw type, size and access. An offset screwdriver is an alternative in confined spaces where a conventional one cannot be used.
Safety & limits
- Do not use a slotted screwdriver with damaged tips, broken handles, or bent shafts. Keep the handle clean to reduce slipping. Never use the screwdriver to test if a circuit is live.
