Screwdrivers

Screwdrivers are probably the most misused hand tool. Using one as a pry bar, chisel or punch breaks the tip and drives it into your hand.

Using screwdrivers safely

• Match the tip type and size to the screw head exactly.
• Hold small parts in a vise or clamp, never in your palm.
• Keep the screwdriver straight in line with the screw.
• Use insulated screwdrivers (rated 1000 V, with the double-triangle symbol) for electrical work, and only if you’re qualified and the circuit is de-energized when required.
• Replace screwdrivers with worn, rounded or chipped tips or cracked handles.

• Don’t use a screwdriver as a pry bar, chisel, punch, scraper or paint can opener.
• Don’t strike a screwdriver with a hammer (unless it’s a through-tang driver made for it).
• Don’t use pliers on the handle for extra torque.
• Don’t carry screwdrivers in your back pocket.
• Don’t assume tape on a handle makes it insulated.
