Balax 11065-000 Thread Forming Tap 5-40 Unc Plug Hss

Product Description

The BALAX 11065-000 is a thread forming tap designed for cutting 5-40 UNC internal threads in through-hole applications. Unlike cutting taps, thread forming taps displace material rather than remove it, producing stronger threads with a better surface finish and no chips to clear. This tap is manufactured from high-speed steel with a bright uncoated finish and features a plug chamfer with 4 chamfered threads for controlled entry. The H5 thread limit and Class 2B fit designation make it suitable for standard-tolerance threaded fastener applications in metal components. It is typically used by machinists, maintenance technicians, and production shops working with small-diameter fastener holes.

This tap is suited for through-hole threading in soft to medium-hardness metals where chipless thread forming is preferred over traditional cutting. The plug chamfer style makes it appropriate for use in both through holes and applications where the tap can be started with moderate alignment control. The BXP series designation indicates compatibility with BALAX thread forming tap standards. Right-hand thread direction is standard for conventional 5-40 UNC fastener applications in light-duty assemblies, instrument enclosures, and precision components.

Key Features

• Thread forming design displaces material for stronger, chip-free threads
• 5-40 UNC thread size with right-hand thread direction
• Plug chamfer with 4 chamfered threads for guided entry
• High-speed steel construction for durability in metalworking applications
• H5 thread limit with Class 2B fit for standard-tolerance results
• No coolant-through requirement simplifies setup

Compatibility

Designed for through-hole threading operations requiring 5-40 UNC right-hand threads at a Class 2B fit. Suitable for use in standard tap handles and machine tapping setups compatible with a 0.141-inch shank diameter.

Installation Notes

Thread forming taps require a properly sized forming tap drill - the recommended hole size differs from standard cut tap drill charts, so consult a thread forming drill size reference before drilling. Apply appropriate tapping fluid or cutting oil before use to reduce friction and extend tap life. Secure the workpiece and ensure proper tap alignment before applying torque. This tap is installed by machinists or maintenance technicians using a tap wrench or machine tapping fixture.
