The Bordo 5G x 44 UNF Bottoming HSS Tap is a professional-grade threading tool from Bordo’s High Speed Steel (HSS) hand and machine tap range, engineered for cutting fine Unified National Fine (UNF) internal threads. Designed with a bottoming lead, this tap is ideal for producing full-depth threads at the base of blind holes — delivering strong engagement and precision performance in workshop, fabrication and trade applications.
Manufactured from durable high speed steel, this 5G diameter tap features a 44 threads-per-inch (TPI) UNF profile — a fine thread form commonly used where increased tensile stress area and tighter thread engagement are required. The UNF series offers resistance to thread stripping and is suitable for applications where material wall thickness is limited or where fine pitch threading is necessary. Bottoming taps have a lead of two threads and are typically used after a taper or intermediate tap to finish threads cleanly at the bottom of blind holes. Suitable for hand or general machine use, this tap is designed for reliable performance across a range of medium tensile materials.
Bordo’s precision engineering and trusted quality standards ensure dependable results — and with Industrial Shed’s fast dispatch and trade support, you’ll have the right threading tool ready when you need it.
