Cdi 61SM Ct Screwdriver Torque Limiting Adjustable

Product Description

The CDI 61SM is an adjustable torque-limiting CT screwdriver designed for precision fastening applications where controlled torque is critical. It features a 1/4-inch hex drive, an overall length of 5.5 inches, and a tri-lobular handle for a secure grip during use. The 61SM operates in the counterclockwise limiting direction and covers a torque range from 0.1 ft-lb to 0.52 ft-lb, with accuracy rated at plus or minus 6 percent per ASME B107.300-2010 and N.I.S.T. standards. The set includes six models with torque settings ranging from 20 in-oz to 40 in-lb. This screwdriver is used by HVAC technicians, electricians, and assembly professionals who need repeatable torque control on small fasteners.

The 61SM is suited for light-duty precision fastening in residential and commercial service work. Its compact 5.5-inch overall length makes it practical in tight spaces common in panel work, equipment access areas, and component assembly. The counterclockwise limiting direction prevents overtorque during installation. Technicians working on small screws and hex-drive fasteners benefit from the adjustable settings that span a wide range without requiring multiple tools on the job.
