The Draper 3 Piece 1/2" Drive Spark Plug Socket Set is a professional socket set designed for safe and efficient spark plug removal and installation across a range of vehicle applications. This comprehensive set includes three essential sizes to cover the most common spark plug thread specifications found in petrol engines. Each socket in this set is manufactured from chrome vanadium steel, forged and heat-treated through a hardening and tempering process to deliver excellent durability and resistance to wear. The chrome plated and polished finish provides effective corrosion protection, ensuring the sockets maintain their professional appearance and performance over time. A key feature of these spark plug sockets is the internal rubber insert fitted to each one, which serves the dual purpose of protecting delicate spark plug insulators during removal and holding the spark plug securely in place for easier installation. The 6-point deep socket design ensures positive engagement with spark plugs, whilst the knurled ring on each socket provides additional grip for confident handling during use. This set is ideal for professional mechanics, mobile service technicians and workshop environments where regular spark plug maintenance is required. The 1/2" square drive fitment makes these sockets compatible with standard ratchets, torque wrenches and extension bars commonly found in automotive toolkits.
