The Bordo 7/16" x 18 BSF HSS Tap Set is a professional-grade British Standard Fine (BSF) hand and machine threading kit engineered for precision internal thread cutting in medium tensile materials. Designed for workshop, fabrication, industrial and maintenance applications, this set delivers dependable fine-pitch BSF thread performance suitable for a wide range of machinable materials.
Manufactured from durable High-Speed Steel (HSS), this BSF tap set utilises the classic British Standard Fine thread form — a fine-pitch variant of the traditional Whitworth family of threads, first introduced in 1908 and specified under BS84:1956 — offering improved tensile stress area and resistance to stripping compared with coarser threads of similar size. The set includes a combination of taper, intermediate and bottoming taps, providing full coverage from thread start to deep blind hole finishes. With a 7/16" nominal diameter, 18 threads per inch (TPI), a drill diameter of approximately 9.8 mm and an overall length of ~85 mm, this kit is ideal for both hand and general machine tapping.
Bordo is recognised across Australia for supplying high-quality industrial tooling backed by strong manufacturing standards. Industrial Shed ensures you have fast access to trusted trade-grade threading tools when you need them on site or in the workshop.
