Drive Torx-head fasteners with confidence using the Century Drill T30 star insert bit. The S2 tool steel body is heat-treated to 58-62 HRC, giving an ideal balance of hardness and toughness - resisting wear while flexing rather than shattering under high torque. T30 is the standard size for structural wood screws.

• S2 tool steel, heat-treated to 58-62 HRC
• 1" overall length, 1/4" hex shank
• Fits hand drivers, 1/4" hex bit holders, impact-ready chucks, and quick-change collets
• Precision-machined tip for secure fastener engagement
• T30 size for structural wood screws (HeadLok 2-7/8", LedgerLok 3-5/8", PowerLag), heavy lag screws, and many automotive brake/suspension fasteners
• MPN 68430 (Century 684XX Torx insert bit family: last 2 digits = Torx number)

Tip: Seat the bit fully in the recess before applying torque. Structural T30 screws develop high torque late in the drive - use a corded drill or high-torque impact and let the bit hit bottom of the recess to avoid cam-out and stripped heads.
