BulletPoint6 : Easy Installation with Square Head: Full-thread square head bolts offer simple, tool-friendly tightening with a wrench—great for quick assembly in tight spaces or heavy-duty projects. BulletPoint7 : Secure Cup Point Design: The cup point digs into surfaces for a tight, vibration-resistant hold, ensuring reliable locking of gears, pulleys, or shafts without slipping. BulletPoint8 : The cup point has a circular, concave tip that digs into the mating surface (e.g., a shaft or gear). This creates a strong, frictional grip, preventing slippage or rotation under load. BulletPoint9 : The cup point works well on softer metals (e.g., aluminum) or even harder surfaces (e.g., steel), biting in without needing a pre-drilled spot like a cone point might.
