The WILLIAMS COMFORT PRODUCTS SDR-26-TH is a slotted screwdriver with a 5/16-inch blade width and a 6-inch round shank. It is a hand tool used for driving and removing slotted-head fasteners encountered during installation, adjustment, and service work on HVAC, heating, plumbing, and related mechanical systems. At 0.38 pounds, it is a lightweight, single-piece tool suited for tight-access service tasks. HVAC technicians, plumbers, and general service professionals keep this style of driver in their kit for terminal screws, access panel fasteners, and control-component hardware.
This screwdriver is appropriate for residential and light commercial service applications where slotted fasteners are present. Typical uses include tightening or loosening terminal connections, mounting screws on control boards or valve assemblies, and general panel work during equipment installation or routine maintenance. The round shank profile allows the use of a wrench for additional torque when needed on stubborn fasteners.
Designed as a general-purpose slotted screwdriver for use with standard slotted-head fasteners common to HVAC, heating, plumbing, and mechanical service applications.
This tool is used by HVAC technicians, plumbers, and service professionals for fastener work on mechanical and electrical components. Always de-energize equipment and follow applicable OSHA and NEC safety procedures before accessing electrical terminals or control components. Use only the appropriate blade size for the fastener slot to prevent cam-out and fastener damage. Inspect the tool for wear or damage before each use.
