Balax 10323-010 Thread Forming Sti Tap 2-56 Unc H3

Product Description

The BALAX 10323-010 is a thread forming STI tap designed for producing Screw Thread Insert (STI) tapped holes in a variety of materials. Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger threads with no chips to clear. This tap features a bottoming chamfer for threading close to the bottom of a blind hole and is manufactured from high-speed steel with a bright uncoated finish. The H3 thread limit provides a controlled tolerance class suited to standard STI insert applications. Machinists and maintenance technicians use this tap in hand tapping and machine tapping operations where helical inserts will be installed.

This tap is sized for 2-56 UNC threads and is appropriate for use in precision tapping of small-diameter holes requiring STI preparation in metals and other machinable materials. The bottoming chamfer makes it well suited for blind hole applications where full thread depth near the bottom is required. It belongs to BALAX Series BXSTI, which covers the full range of thread forming STI taps for helical insert preparation.

• H3 thread limit provides consistent tolerance for standard STI insert fitment
• High-speed steel construction offers durability across a range of machinable workpiece materials
• Bright uncoated finish suitable for use with standard tapping fluids and lubricants
• Part of the BALAX BXSTI series for Screw Thread Insert tap applications

Compatibility

Designed for use in STI tapping applications requiring a 2-56 UNC thread forming tap with H3 tolerance, intended for preparation of holes that will receive helical thread inserts.

Installation Notes

Installation should be performed by qualified machinists or maintenance technicians familiar with tapping procedures and STI insert systems. Always secure the workpiece and use a recommended tapping fluid or cutting oil appropriate for the workpiece material before tapping. For hand tapping, use a properly sized tap wrench and maintain alignment perpendicular to the workpiece surface to avoid tap breakage. Follow the insert manufacturer's installation instructions after tapping is complete.
