Greenfield Threading 174534 Tap Set 5/8"-11 UNC
This new tap set from Greenfield Threading contains bottoming, plug, and taper taps for creating 5/8"-11 UNC threads. Each high-speed steel tap features a TiN coating and four flutes for efficient chip evacuation. The set suits machinists and maintenance technicians who need to cut internal threads in steel or other ferrous materials. It covers three common starting conditions in one package.
For internal thread cutting only; not a die set
This product suits professionals cutting new internal threads or chasing damaged ones in through-holes and blind holes. It does not suit users who need external threading tools such as dies or hex die stocks. Buyers requiring left-hand thread taps or a different thread limit class should look elsewhere. The set addresses right-hand UNC threads exclusively.
5/8"-11 UNC thread size with H3 limit
The taps are ground to a 5/8"-11 UNC thread size with an H3 thread limit for a 3B class of fit. This specification determines whether the finished thread meets the required tolerance for the application. Verify the thread size and limit against your engineering drawing before purchase. The 4-flute geometry supports the cutting action in standard materials.
Highlights
- UNC threading for standard compatibility

Questions about this item
At what thread limit does the 5/8"-11 UNC tap set start to lose accuracy under sustained threading?
The tap set is manufactured to an H3 thread limit and Class of Fit 3B, which defines the tolerance range for the 5/8"-11 UNC threads during continuous use.
How much heat builds up in the high-speed steel taps when running all day in a power tool?
The high-speed steel construction with TiN coating is designed to dissipate heat during extended tapping operations in steel and other ferrous materials.
What shank size must my tap wrench or power-tool holder accept to drive these 5/8"-11 taps?
Each tap has an overall length of 3 13/16 in and a thread length of 1 13/16 in, so the holder must accommodate that shank diameter and length.
