Sea-Dog Nylon Bimini Top Head Screw, 1/4-28 x 1-3/8 Inch, Part 273568-1

The Sea-Dog 273568-1 Head Screw is the adjustment screw used with Sea-Dog's Jaw Slide and Bracket Fitting system for Bimini tops. It is molded from UV resistant nylon and threads into the jaw slide, where tightening it locks the slide in place along the mounting bracket after you have positioned the Bimini top frame where you want it. Loosening the screw lets the jaw slide glide freely along the bracket for repositioning, so you can fine-tune the angle and tension of your Bimini top canopy without removing any hardware from the boat.

This is a standard 1/4-28 fully threaded machine screw with a flat head, measuring 1-3/8 inches in overall length. It is molded in black nylon to match Sea-Dog's Jaw Slide and Bracket Fitting line and is sold as a pair. Because it is a nylon component rather than metal, it resists corrosion and UV degradation from long-term sun and saltwater exposure, which is important for hardware that stays exposed on deck. The 273568-1 head screw is a replacement or spare part for boat owners maintaining an existing Sea-Dog jaw slide bracket system, letting you replace a stripped, cracked, or lost screw without buying a whole new slide and bracket set.
