The Bordo ⅝″ x 18 UNF Taper HSS Tap is a professional threading tool engineered to cut fine internal threads to the Unified National Fine (UNF) standard. Designed for both hand and general machine use, this taper tap delivers smooth thread engagement and accurate starts — making it ideal for precision threading tasks in fabrication, maintenance and mechanical assembly applications.
Manufactured from durable high speed steel (HSS), this UNF taper tap features a 5/8″ major diameter and 18 threads per inch (TPI), offering a fine thread profile with enhanced tensile strength and resistance to thread stripping. The taper lead (typically eight threads) gradually engages the material to help start the thread cleanly and reduce the risk of misalignment or chatter during cutting. Suitable for use in metals such as steel, aluminium, brass and other workshop materials, this tap is a reliable choice for professional tradespeople.
Bordo tools are recognised in Australia for their quality manufacturing standards and reliable industrial performance. Industrial Shed ensures fast access to these trusted trade-grade taps when you need them on site or in the workshop.
