How to Install/Use

• Driving Screws

  Driven screws turn a shaft using a power tool or manual screwdriver to insert it into a material. The bit type corresponds to the screw head to ensure proper engagement. In doing so, this allows for the even distribution of force and prevents stripping. Also, holding the drill at a perpendicular angle to the material ensures a straight insertion and secure fastening.

• Removing Screws

  The opposite process of driving screws is screw removal. Here, the applied rotation is in the counter direction. Doing this allows the screw to come out intact. This is particularly important for maintenance or disassembly during operations. Moreover, using the appropriate bit type prevents damage to the screw or material. This, in turn, expedites the process and ensures easy re-use of the fastener if needed.

• Extractor Functionality

  Screw extractor bits are specifically designed to remove broken or damaged screws. Basically, an extractor bit features a reverse thread that grips the embedded screw when the driver turns it. Some of the applications of this tool include those cases of a stripped head or corroded fastener. Note a screw extractor bit works by providing a solution to a common problem, which is downtime and damage to equipment.

Maintenance and Repair

• Routine Inspection

  This involves checking the condition of the bits periodically, looking for things like wear and tear or damage to the tools. Catching small problems early before they get big will help keep everything running smoothly.
