Electric Torque Screwdrivers are designed for precision torque control and ensure product quality, cost savings and a reduction in overall assembly failures. The failure of a three-cent fastener that isn’t properly tightened can lead to catastrophic or latent failures. Fasteners that are insufficiently torqued can vibrate loose, and excessive torque can strip threaded fasteners or damage parts. Using a quality assembly torque tool is important for many companies to ensure that proper torque is being applied and maintain requirements associated with the ISO 9001 quality standard.
Listed below is quick reference guide for selecting from the various common electric torque screwdrivers available.
Direct Plug-in Electric Screwdrivers These tools plug directly into a power outlet without the need for a transformer (power supply). A direct plug-in electric screwdriver is intended for low to medium cycle applications. The electric screwdriver is designed to install a fastener then rest for 3.5 seconds before you install the next fastener. The reason is that all the electronics are built into the power tool and it may over-heat and damage the tool. These reliable power tools automatically shuts-off when the preset torque has been reached.
DC Powered Electric Screwdrivers For high production applications, an electric screwdriver with a transformer (power supply) is built for these applications. Low voltage electric screwdriver automatically stops when the preset torque has been reached. Various models and styles.
Brushless Electric Screwdriver: Designed for high production environments, the electric screwdriver features a high performance brushless motor design that provides durability and reduces the standard maintenance costs for electric screwdrivers.
ESD Electric Screwdriver: Prevent the occurrence of electrostatic discharge. Improve production yields, manufacturing costs, product quality, product reliability, reputation and profitability.
Soft-Stop Electric Screwdriver: “Soft-Stop” clutch prevents shock to sensitive assemblies like disk drives, plastics, and electronics. Ergonomically designed clutch and body case reduces impact and vibration transmitted in the screw fastening process.
Robotic Electric Screwdriver: Built for robotic and automated applications. The durable robotic screwdrivers deliver reliability and precision torque control.
Clean Room Electric Screwdriver: The screwdriver is equipped with a vacuum apparatus as well as a suction head to insure complete removal of fine particles generated during the tightening process in clean rooms.
Vacuum Electric Screwdriver: The screwdriver is fitted with a suction head that holds the screw on the bit, enabling the operator to pick up the fastener with the tool from a screw presenter or a shaker box. This is an effective, time saving device that works with most fasteners. Vacuum adapters kits can be purchased separately mounted onto an electric screwdriver.
