RS PRO Threading Tap, 2 BA Spiral Point, Machine Use, HSS, Blue Steam Tempered Finish, 58 mm Length, 455-986

The RS PRO 455-986 Threading Tap is a high-quality tool designed for precise formation of 2 BA British Association standard threads in a range of engineering and industrial materials. Crafted from high speed steel (HSS), this tap provides robust durability and long operational life even under demanding workshop conditions. The spiral point geometry facilitates excellent chip evacuation and prevents swarf clogging during tapping, making it specially suited for machine operations while remaining versatile enough for manual hand tapping.

This model features a blue steam tempered finish, minimizing friction between the tap and workpiece, which further assists in producing accurate, smooth threads and reducing tool wear. The right-hand threading direction and spiral point style allow for confident operation on through holes, optimizing cutting efficiency and ensuring a clean thread form. Its overall length of 58 mm and shank diameter of 5 mm fit easily into most industry-standard tap holders and tapping equipment.

The RS PRO 455-986 tap is compliant with ISO taps standards, ensuring consistent performance and compatibility with metricized quality systems. The 2 BA thread size and 0.81 mm thread pitch are engineered for use on electronics enclosures, mechanical assemblies, panel mount fixings, and classic industrial fastener installations where the BA thread system is specified. The tap can be employed to cut new threads or restore worn threads for maintenance, assembly, and manufacturing tasks.

Suitable for use in industrial workshops, maintenance departments, electrical panel construction, laboratory prototyping, and light manufacturing environments, this threading tap is an essential addition to the toolkit of engineers, technicians, and machinists working with BA-standard fastenings. The HSS material delivers reliable hardness and resistance to deformation, while the blue steam finish offers added surface protection and a quality threaded finish.

Engineers and assembly specialists appreciate the tap's compatibility with both machine and hand operations, eliminating the need for a dedicated lead tap. The spiral point shape directs chips forward, reducing the risk of thread damage or jamming. This tap is ideal for production runs or repair work requiring high reliability in threading performance.
