Single and double upset spool bolts
Single and double upset spool bolts are specialized steel fasteners for utility poles, differing by forged plates near the insulator end: single upset has fewer plates on one side for specific insulator angles, while double upset has more plates on both sides, offering broader support for horizontal spool insulators, especially for neutral or power lines, providing enhanced strength and stability.
