Draper Tamper Proof Impact Spline Set, 1/2" Sq. Dr. (8 Piece)

The Specialist Spline Set for VAG Vehicle Servicing

If you work on Volkswagen, Audi, SEAT, Škoda, or other VAG group vehicles, you'll know that tamper proof spline fixings are commonplace across suspension components, steering hubs, and drain plugs. Standard sockets simply won't engage. The Draper ISS8 Tamper Proof Impact Spline Set is purpose-built to tackle these fasteners head-on – with the correct profile geometry, the right material strength, and the versatility of two bit lengths for every access challenge.

Two Lengths for Maximum Versatility

Each of the four metric sizes – M12, M14, M16 and M18 – is supplied in both a 44mm short length and a 77mm extended length, giving you eight bits in total. The shorter bits excel in confined spaces where a standard-length socket would foul surrounding components, while the longer bits provide the reach needed for deep-set or recessed fasteners. Having both lengths to hand means you're never caught short on the job.

Forged Chrome Molybdenum Steel – Built for Impact Use

Every bit in the ISS8 set is forged from chrome molybdenum (Cr-Mo) steel, then hardened, tempered, and finished with a blackened coating. Chrome moly is the material of choice for impact-rated tools – it offers exceptional tensile strength and resistance to the sudden shock loads generated by pneumatic and electric impact drivers. Where lesser materials crack or round out under pressure, these bits maintain their profile integrity for consistent, reliable engagement.

Compatible with VAG Suspension, Steering & Drain Applications

VAG engineers specify tamper proof spline fixings across a wide range of critical fastening points. This set covers the most commonly encountered sizes for:

• Suspension component removal and refitting – subframe bolts, wishbone mounts, and strut fasteners
• Steering hub work – steering rack and hub carrier fixings on Audi, VW, SEAT and Škoda platforms
• Drain plugs – sump and gearbox drain plugs using spline profiles across VAG model ranges

1/2" Square Drive – The Right Drive for High-Torque Work

The 1/2" square drive fitment is the industry standard for high-torque fastening applications. Suspension and steering fasteners often require significant torque to break free – particularly on older or corroded vehicles – and the 1/2" drive ensures the set works seamlessly with your impact wrench, breaker bar, or torque wrench for both removal and refitting.

Supplied in a Sturdy Storage Case

The full 8-piece set is housed in a dedicated plastic storage case with individual bit holders, keeping your set organised, protected, and ready for use. The case is ideal for van storage, toolbox drawers, or workshop shelving.
