The Bordo 1/4″ x 28 UNF Intermediate HSS Tap is a professional-grade threading tool from Bordo’s High Speed Steel range, engineered to deliver precise internal fine-pitch threads in both hand and general machine applications. Designed for workshop and trade use, this intermediate tap produces accurate Unified National Fine (UNF) threads true to a pre-drilled pilot hole for reliable assembly and fastening work.
Manufactured from durable high-speed steel (HSS) with a straight intermediate flute design, this tap features a 28 threads per inch (TPI) pitch and an intermediate lead (four threads), making it ideal for most general-purpose threading tasks. The fine-pitch UNF form offers greater tensile stress area and improved resistance to stripping compared with coarse thread equivalents — especially beneficial in thin-wall or high-load applications. Suitable for use in materials such as aluminium, brass, bronze, plastics and mild steel, this intermediate tap is a dependable choice for both workshop and on-site threading jobs.
Bordo is a trusted industrial tooling brand in Australia known for quality-engineered taps and dies, and Industrial Shed ensures you have fast access to this trade-grade UNF tap when you need it on site or in the workshop.
