Market leader in preventing rounded fasteners
Star fasteners don't fail in the open. They fail buried behind brackets, recessed in housings, and tucked where a straight-on approach simply isn't possible. The GripEdge 9-PC RPT™ Long Ball Star Bit Driver Set (BST9LS) was designed from the ground up for professionals who can't afford to lose a fastener or strip a bolt in a difficult location.
Our second-generation Ball Star geometry delivers up to 15.5° of pivot, letting you engage angled or obstructed fasteners that conventional bits can't reach. And because access means nothing without grip, every bit features our patented Rounding Prevention Technology (RPT™); flat-face engagement that drives the sides of the fastener instead of the corners, delivering up to 50% more grip on intact fasteners and up to 400% more grip on damaged fasteners than standard tools.
Built for the Hard-to-Reach
- Fits Torx® Fasteners — Star profile is fully compatible with standard Torx® fasteners, sizes T10 through T50.
- Second-Generation Ball Star Tips — Up to 15.5° of pivot angle for angled engagement when straight-on access isn't possible.
- RPT™ Rounding Prevention Technology — Increased fastener contact reduces the risk of rounding on both intact and damaged star fasteners.
- 6" Overall Length — Long-reach design for recessed or obstructed star/Torx®-style fasteners in automotive, industrial, and heavy equipment applications.
- S2 Tool Steel Construction — Each bit is precision-machined from S2 tool steel for maximum durability.
- Slim Profile — Improves access in confined areas without sacrificing strength.
- High-Visibility Markings — Large stamped size markings with black ink fill stay readable in low-light or dirty shop conditions.
