■ Stopper for The Straight Leader Bushing Screw plugs are commonly used as a stopper to hold straight leader bushings in place. The bushing is provided with a groove on its outer circumference where the screw plug is locked in. Since the screw plug does not directly hold the bushing's thin wall, deflection of its internal diameter can be minimized. When L = 10 (d = 8–20) or L = 15 (d = 25), screw plug is the value in ( ). Leader bushing internal diameter (d) Applicable Screw Plugs 8–20 MSW 6 (4) 25–60 MSW 8 (6)
