Osg 1013702 Straight Flute Tap 6-32 Unc Plug 3B Hss

Product Description

The OSG 1013702 is a straight flute tap designed for cutting 6-32 UNC internal threads in a wide range of metals. Built from high-speed steel, it delivers consistent thread geometry through repeated use in production and maintenance environments. The plug chamfer configuration eases entry into through-holes, and the H2 thread limit ensures controlled fit tolerance for 3B class threads. With an overall length of 2 inches and a thread length of 0.6875 inches, this tap suits standard hand-tap holders and machine setups alike. Machinists, toolmakers, and maintenance technicians working with small-diameter fastener threads will find this a reliable utility tap.

This tap is suited for tapping 6-32 UNC threads in both manual and CNC-assisted drilling operations. The straight flute design makes it appropriate for through-hole and short blind-hole applications where chip evacuation is not a critical constraint. It is well matched to light-duty production runs and repair threading in ferrous and non-ferrous materials including aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel.

Key Features

• 6-32 UNC thread form with right-hand thread direction
• Plug chamfer for guided entry into pre-drilled through-holes
• H2 thread limit for accurate 3B class of fit tolerance
• High-speed steel construction for broad material compatibility
• 3-flute straight design handles a range of ferrous and non-ferrous materials
• Compact 2-inch overall length fits standard tap holders and collets

Compatibility

Designed for cutting 6-32 UNC threads in aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel workpieces. Intended for use in standard tap holders accepting this shank size and geometry.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with tapping operations. Ensure the workpiece is securely fixtured and the correct tap drill size for 6-32 UNC threads is used before beginning the tapping operation. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Do not force the tap; back off periodically to break chips and prevent tool breakage.
