Sealey AK3040 40 Piece Alloy Steel Tap and Split Die Set Metric

The Sealey AK3040 is a comprehensive 40-piece metric tap and die set designed for creating and repairing internal and external threads on metal components. Manufactured from high-quality alloy steel, this professional threading kit provides essential tools for engineers, mechanics, and fabricators working with metric fasteners and threaded assemblies. The split dies feature precision-machined lead-ins that guide the threading process, reducing the risk of cross-threading and ensuring clean, accurate thread formation from the initial cut. The included die holder incorporates a self-centring mechanism that maintains perpendicular alignment during thread cutting, crucial for producing straight threads that mate correctly with corresponding fasteners. This complete set covers the most commonly used metric thread sizes from 3mm to 12mm across various pitch configurations, making it suitable for automotive repair, machinery maintenance, and general engineering work. The inclusion of both a standard tap wrench and a T-handled tap wrench provides flexibility for working in confined spaces or applications requiring greater leverage. A metric screw pitch gauge is also supplied, enabling quick and accurate thread identification before cutting operations begin. The toolkit arrives in a purpose-designed storage case that keeps components organised and protected between jobs, with each piece having its designated location for easy identification and inventory checks.
