Spline drive fasteners demand precise engagement and robust tooling — the Draper Expert 83566 Spline Bit Set delivers exactly that in a compact three-piece configuration for 1/2" square drive applications. The two spline bits are manufactured from SNCM-V steel hardened and tempered throughout and finished with a shot blasted surface treatment. This material and process combination provides the toughness required to withstand the high torque loads that spline fasteners typically impose. The included 1/2"" square drive bit holder is constructed from chrome vanadium steel hardened tempered and chrome plated for corrosion resistance making it suitable for workshop environments where tooling is exposed to moisture and lubricants. The set comprises one bit holder (10 mm x 1/2"" square drive) one 8 x 30 mm spline bit and one 12 x 75 mm spline bit providing two key spline sizes within a single set. The differing lengths — 30 mm and 75 mm — allow access to fasteners in both open and restricted locations. This is an Expert Quality product within the Draper range reflecting the material specification and manufacturing processes applied to both the bits and the holder. The set is suited to professional automotive and workshop technicians working with spline-head fasteners across a range of vehicle and equipment applications.
