The new DSD-4 torque screwdriver features an integral/adjustable LCD display for convenient torque readings. The unit is designed for screw tightening torque verification and measures in Peak, Real Time, and Peak Down measuring modes (selectable).

The DSD-4 torque screwdriver has an accuracy of ± 0.5% F.S., ±1 LSD and has programmable setpoints that provide both an audible beep and green/red LED indicator for uniform tightening or GO/NO GO testing. In addition, it features a programmable counter that minimizes assembly errors by identifying mis-tightening and/or defective screws. Use the 400 internal memory for peak data recall or RS-232 download for SPC.

The DSD-4 torque screwdriver substantially reduces scrap and rework costs by eliminating over and under-tightening and is ideal for use in a wide variety of applications including the manufacture of electronic, appliance and aerospace assemblies.
