Lang 2585M Tap Set 9/16-12 Unc Carbon Steel 6 Piece

Product Description

The LANG 2585M is a 6-piece tap set covering a thread size range from 1/4-20 up to 9/16-12 UNC. Each tap is machined from carbon steel with a zinc finish applied for corrosion resistance. The set cuts right-hand threads to Unified National Coarse (UNC) standards. Machinists, maintenance technicians, and trade professionals use this type of set for threading operations on ferrous and non-ferrous materials. The zinc coating helps protect the tools from moisture and light corrosion during storage and use. This set is suited for general shop use, field maintenance, and repair work where multiple UNC thread sizes are needed in a single kit.

This tap set is appropriate for repair and fabrication tasks across mechanical, HVAC, plumbing, and industrial maintenance applications. It handles thread repair on bolted assemblies, tapped holes in metal fixtures, and new thread cutting in soft to medium-hardness materials. The range from 1/4-20 to 9/16-12 UNC covers the most commonly encountered fastener sizes in trade and light industrial settings, making it a practical addition to a service truck or shop toolbox.
