Screwdriver Safety and Tips:
Screwdrivers should only be used for their intended purpose, driving or removing screws. Screwdrivers should never be used for prying, punching, chiseling, scoring or scraping.
While both slotted and cross-slotted screwdrivers will fit many fastener sizes, it is best to use screwdrivers of the proper sizes that fit snugly into the slot or recessed portion of the fastener head.
Precision tips have a more consistent symmetry than conventional tip screwdrivers and provide better fit and torque without the danger of slippage
Plastic handles should be made of fire and heat-resistant materials. If properly designed, they give excellent grip. Rubber or vinyl is often used as a non-slip or insulating cover on plastic handles.
Typical screwdriver handles will not insulate the user from electric current.
It is time to discard the tool when the handle of a screwdriver becomes worn or breaks, if the tip is damaged or if the shaft is bent.
Screwdriver slippage can cause injury. Never hold the piece you’re working on in your hand while driving or loosening screws or bolts. Place it on a work surface and use a vice or a clamp to hold the material, whenever possible.
Never use pliers for added turning leverage on the shank of a screwdriver. However, a wrench may be used on square-shank drivers.
Never carry a screwdriver in your pocket.
When using any tool, always wear safety glasses for eye protection.
