How to use a screwdriver safely.

Every screwdriver has its function, and screwdrivers are probably the most misused and abused tools in the workplace. Misuse can impair the effectiveness of the screwdriver by breaking the screwdriver handle, deforming the screwdriver handle, or dulling the tip of the screwdriver. It makes people easy to be injured when using the screwdriver correctly. In order to prevent the user from being injured and maintain the use effect of the screwdriver, we have given a detailed use procedure:

Make the pilot hole

Start by making a pilot hole for the screw in the wood and sheet metal. When driving a screw into the wood it is best to drill a pilot hole first, without a pilot hole the screw will tend to follow the grain of the wood causing the screw to bend. So the pilot holes make sure you drive the screws straight in.

Mounting screws

Pilot holes prevent wood and sheet metal from splinting when screwing in. For small screws in wood and sheet metal, use a punch and an awl to make a pilot hole. For larger-size screws and all hardwood screws, drill a pilot hole with some kind of drilling tool. When using a screwdriver, do not use the screwdriver as a punch, wedge, clamp, or pry bar and need to keep the tip of the screwdriver clean and sharp so that you can get a firm grip on the screw tip, if you find that the tip of the screwdriver is a bit rounded or chipped, Please avoid it. At the same time, it is necessary to keep the handle of the screwdriver clean and intact for a firm grip and to prevent slipping.
Never hold the screw you're working on in your hands, always keep it on the bench or in a vise. Place the screw on the driver's head and use the fingers of one hand to bring the screw and head together. While turning clockwise, apply light pressure to the driver until the screw engages the wood. Keep your screwdrivers in your toolbox or work bag, out of pockets, to prevent getting scratched by the screwdriver head.
continue to use. When the screw's threads engage the wood, move the finger holding the screw over the shank of the screwdriver. Using these fingers as a guide, align the tip directly with the screw. Apply enough pressure to the drive to keep it in the slot.
