The Bordo ⅝" x 18 UNF Intermediate HSS Tap is a professional threading tool designed to cut accurate internal Unified National Fine (UNF) threads in hand and general machine applications. Part of Bordo’s dependable High Speed Steel (HSS) UNF tapping range, this intermediate tap delivers consistent thread creation when used with a correctly pre-drilled pilot hole — ideal for workshop, fabrication and industrial use.
Manufactured from premium High Speed Steel, this tap features a four-thread intermediate lead that ensures reliable and true thread cutting performance. The fine-pitch UNF thread form (18 threads per inch) provides strong internal thread engagement and excellent resistance to stripping, particularly valuable in automotive, machinery assembly and precision maintenance tasks. With a ⅝" (inch) major diameter and UNF thread series, this tap balances tensile strength and fine adjustment capability for demanding applications.
