The WILLIAMS COMFORT PRODUCTS SDP-2-4-TH is a Phillips screw drive fastener measuring 2 inches by 4 inches. Designed for trade installation work, this small but essential hardware component provides a reliable mechanical connection in applications where a Phillips drive pattern is specified. At 0.25 pounds, it ships as a single unit and is suited for use by HVAC technicians, plumbers, and general mechanical contractors who need a standardized fastener for panel, bracket, or access door assemblies.
This screw drive is appropriate for light mechanical and HVAC applications where a 2 inch by 4 inch Phillips fastener is called for. It is sold individually and is well suited for service calls, maintenance tasks, or new installation work where replacing or supplementing existing hardware is necessary.
Designed as an OEM-style replacement fastener for use in residential and light commercial HVAC and mechanical equipment assemblies requiring a Phillips screw drive in a 2 inch by 4 inch size.
Installation should be performed by a qualified HVAC technician or mechanical contractor. Power down all equipment and follow applicable lockout/tagout procedures before accessing panels or assemblies. Use the appropriate Phillips bit size to avoid stripping the drive head. Do not overtighten, as this can damage mounting surfaces or strip threads.
