Drive Torx-head fasteners with confidence using the Century Drill T20 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. The 1" length keeps the bit short and rigid for accurate engagement.

• 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
• T20 size for #6-#8 wood screws, small deck screws, cabinet hinges, and most light-trim Torx fasteners
• MPN 68420 (Century 684XX Torx insert bit family: last 2 digits = Torx number)

Tip: Seat the bit fully in the recess before applying torque. Insert bits cam out and round the screw recess almost instantly under angled load, which is the #1 cause of stripped Torx fasteners. For repeated driving, step up to a longer power bit with torsion zone.
