Torx T20 Screwdriver Bits fit the six-pointed star recess found in electronics, automotive, and appliance assembly. The T20 size suits medium fasteners and sits in the middle of the Torx range, making it one of the most called-for sizes on the bench. Most bits use a 1/4 in hex shank for standard bit holders and power tools. Longer shanks reach deep or awkward fixings without an extension.
Material and coating determine service life. Chrome vanadium steel handles hand-tool torque well. Impact-rated variants resist shock loading from cordless drivers. Check overall length before ordering: 25 mm bits suit compact drivers, and 50 mm or longer bits reach recessed fasteners.
