Torque Screwdriver Selection Guide:
Manual Screwdriver: The manual torque screwdriver is made in two popular designs: inline and pistol grip. Modern manual torque screwdrivers are ergonomic in design and even offer a rubber grip for decreased fatigue. A manual torque driver can have a range of 0 to 180 In Lbs. Application: A manual torque screwdriver is ideal for light duty applications that require basic torque control. These adjustable torque screwdrivers are used in a variety of manufacturing environments. Manual torque screwdrivers are not recommended for high volume screw fastening due to the risk of repetitive operation injury (CTS).
Electric Screwdriver: The electric torque screwdriver is commonly found in three different designs: pistol grip, angle and inline. The electric screwdriver application is mostly used for light assembly applications--such as electronic assembly and small parts assembly. Traditional brushed electric motors and the more efficient brush-less motors are found in electric torque screwdrivers. ESD, soft stop, clean room, rated screwdrivers are available in order to meet the tightest assembly requirements. The torque range for an electric torque screwdriver typically is 0 to 132 In Lbs, with speeds in excess of 2000 RPM. Application: Electric torque screwdrivers are some of the most popular torque screwdrivers available. Electric Screwdrivers are found in light assembly and high volume manufacturing environments. Rather than manual torque screwdrivers, electric screwdrivers help increase productivity by providing the operator with faster means of assembly/ disassembly of the product.
Cordless Torque Screwdriver: The cordless torque screwdriver is powered by 9v, 12v and the modern 14.4v Lithium Ion battery pack. These are great for odd jobs that require mobility and flexibility. Popular designs are pistol grip and angle style. Additional benefits include: Reduced hazards caused by air hoses laying across floors or hanging from the ceiling. Lighter weight with an ergonomic design for operator control. Lower vibration and noise for operator comfort. Application: Cordless torque screwdrivers are the most versatile. Not being restricted by a power cord or air hose allows the operator to access hard to reach areas and provides a safer work environment. Most models include LEDs on the front of the tool to provide added visibility to the operator during the assembly process. Cordless torque screwdrivers can be found in automotive, aerospace, electronic assembly, and general industry manufacturing environments.
Pneumatic Torque Screwdriver: The pneumatic torque screwdriver is still widely used for assembly requiring higher levels of torque and faster cycle times. They are commonly found in automotive assembly, aerospace, electronic, and marine applications. Pneumatic screwdrivers require a pressurized air source that provides a constant supply to be effective. Torque ranges for this type of torque screwdriver are 0 to 110 In Lb and can reach speeds of 1000 RPM. Application: Pneumatic torque screwdrivers are some of the most reliable tools available. Pneumatic torque screwdrivers are ideal for assembly applications that require faster speed and high cycle rates. Compared to other torque screwdrivers, pneumatic screwdrivers provide the largest variety of high torque models. Pneumatic screwdrivers are found in almost every manufacturing environment.
