Value Collection MSC-04426326 6-32 Unc Straight Flute Tap Hss

Product Description

The VALUE COLLECTION MSC-04426326 is a straight flute tap designed to cut 6-32 UNC internal threads in through-holes and shallow blind holes. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable performance across a wide range of standard shop metals. It features a plug chamfer with 3 to 5 chamfered threads, which provides a balance between starting ease and thread engagement. The H2 thread limit holds tight tolerances for a 3B class of fit, making it well-suited for precision fastener applications. Machinists, toolroom technicians, and maintenance professionals install this tap by hand or with a tapping machine.

This tap is used in general machining, maintenance, and repair operations where 6-32 UNC threads are required. It is appropriate for threading operations in aluminum, mild steel, brass, and similar machinable materials. With a 3 flute design, it offers good chip clearance and stable cutting action in standard through-hole and shallow blind-hole applications. The plug chamfer style makes it a common choice as a general-purpose starting tap when the threading operation begins from the open end of a workpiece.

Key Features

• 6-32 UNC thread form for standard inch-series fastener compatibility
• Plug chamfer with 3 to 5 chamfered threads for easy starting and balanced engagement
• 3 flutes for adequate chip clearance in through-hole and shallow blind-hole work
• H2 thread limit maintains tight tolerance for 3B class of fit
• High-speed steel construction resists wear under standard tapping speeds
• Bright, uncoated finish suitable for use with cutting fluid or tapping oil

Compatibility

Designed as a standard replacement or general-purpose tap for applications requiring 6-32 UNC internal threads in compatible tapping chucks, T-handle tap wrenches, or tapping machines that accept straight-shank tools of this size.

Installation Notes

This tap is installed by a machinist or maintenance technician using a T-handle tap wrench, tap holder, or tapping machine. Secure the workpiece firmly before starting. Apply an appropriate cutting fluid or tapping oil to extend tool life and improve thread quality. Back the tap out periodically to clear chips, particularly in deeper holes, and avoid forcing the tap to prevent breakage.
