The Bordo 5/16″ × 22 BSF Taper HSS Tap is a professional British Standard Fine (BSF) taper hand and machine threading tap engineered for precision internal thread cutting in medium tensile materials. Built to BSF standards — a fine thread form derived from the British Standard Whitworth system — this taper tap is ideal for workshop, fabrication, maintenance and general trade threading jobs where a reliable start and accurate thread are required.
Manufactured from durable High Speed Steel (HSS), this BSF taper tap features a fine 22 threads-per-inch profile and a taper lead (typically eight threads) that allows easier entry and better alignment when starting a thread, especially in challenging or high-precision holes. Designed for both hand and general machine use, it delivers dependable performance and strong thread results across a range of materials.
Bordo is a trusted Australian industrial tooling brand known for consistent quality and performance. Industrial Shed ensures fast access to trusted Bordo threading tools when you need them on site or in the workshop.
