Description

The 21mm Sealey 3/8" Drive Hexagon Spark Plug Socket is designed for larger spark plug applications, making it ideal for working on performance vehicles, larger engines, and specialist automotive applications. This cold-forged Chrome Vanadium steel socket delivers professional-grade performance with exceptional durability. The 21mm configuration accommodates the larger spark plug sizes found in many modern engines, particularly in performance and commercial vehicle applications. Hardened and tempered for maximum strength, the socket features a chrome plated finish that resists corrosion and maintains its appearance even after extensive use.
