Value Collection MSC-04428322 Straight Flute Tap 10-32 Unf

Product Description

The VALUE COLLECTION MSC-04428322 is a straight flute tap designed for cutting internal 10-32 UNF right-hand threads in through-holes and shallow blind holes. Built from high-speed steel with a bright, uncoated finish, this plug chamfer tap features four flutes and an H2 thread limit, making it well suited for general-purpose tapping in a wide range of ferrous and non-ferrous materials. The plug chamfer provides a gradual lead-in for smooth thread engagement. With an overall length of 2.375 inches and a thread length of 0.875 inches, this tap fits standard tap wrenches and machine holders used in production and maintenance environments. Installation is performed by machinists, tool-and-die technicians, and maintenance mechanics.

This tap is used in manufacturing, maintenance, repair, and overhaul operations where 10-32 UNF threaded holes are required. It is appropriate for use in manual tapping with a tap wrench or T-handle driver, as well as in low-speed machine tapping setups. The 3B class of fit produces a standard tolerance thread suitable for most commercial fastener applications. Typical materials include mild steel, aluminum, brass, and similar machinable metals encountered in light industrial and mechanical assembly work.

Key Features

• 10-32 UNF thread form with right-hand cut direction
• Plug chamfer for gradual thread lead-in in through-holes and shallow blind holes
• Four straight flutes for chip clearance in short-chipping materials
• H2 thread limit for standard 3B class of fit tolerance
• High-speed steel construction for durability across common machinable metals
• Bright, uncoated finish compatible with cutting oils and standard tapping fluids

Compatibility

Designed as a standard replacement or production tap for applications requiring a 10-32 UNF, 3B class of fit, plug chamfer, straight flute tap in high-speed steel.

Installation Notes

Always power down and lock out any machine before changing or loading taps. Use an appropriate cutting fluid or tapping oil to extend tool life and improve thread finish. Align the tap perpendicular to the workpiece surface before applying torque to avoid tap breakage and thread distortion. Straight flute taps are best suited for through-holes or shallow blind holes where chips can exit freely; use a spiral point or spiral flute tap for deep blind holes.
