Helicoil Tap Drill Chart and Chzrt Minimum Minor Diameter [D 1min ]. Nominal Size in Inches and Threads per Inch. They are fit into thread tapped holes to form internal threads with nominal size. For Screw- Lock inserts, a tolerance class 4H5H or 3B is recommended in order to develop higher locking torques. Tap Chart Helicoil Threads — provides tap sizes and drill sizes for Helicoil threads. Heli-Coil drilling data — inch. This uelicoil of tap has only 1 to 2 pitch thread chamfer.

Minimum Pitch Diameter [D 2min ]. This thread form is used in materials with low tensile strength which makes cchart more resistance against stripping internal threads.

External threads of this Fine Series have greater tensile stress area than comparable sizes of the coarse series. Conventional shop practice and production procedures, speeds, feeds and nelicoil hwlicoil be used in combination with proper fixturing and good tapping machines or tapping heads.

Maximum Minor Diameter [D 1max ]. Most commonly used type for general engineering applications.

The Fine series is suitable when the resistance to stripping of both external and mating internal threads equals or exceeds the tensile load carrying capacity of the externally threaded member.

This type of tap has over 4 pitch thread chamfer.

HELICOIL SCREW THREAD INSERT (STI) TAPPED HOLE DIMENSIONS

Minimum Major Diameter [D min ]. The higher and more consistent torques are met by the screw locking inserts when assembled and tested in Class 3B tapped holes. Minimum Major Diameter [D min ]. Helicoil Tapping Data — Metric Heli-Coil taps in various types and styles produce holes for Tolerance Classes 4H5H or 3B and 5H or 2B for use in the general range of aluminums, magnesiums, mild steels, free machining stainless steels and other free machining materials.

The tapped hole must be held within the stated pitch diameter limits for the required Tolerance Class of fit for the installed Heli-Coil insert. Minimum Drilling Depth [G]. During the assembly operation, the diameter of the leading coil is reduced due to applied torque and this permits it to enter the tapped thread.

Plug style tap is widely used in through holes and where there is sufficient room at helicoi, bottom in blind holes. Minimum Pitch Diameter [D 2min ]. It is also used where the length of engagement is short, where a smaller lead angle is desired, where the wall thickness demands a fine pitch, or where finer adjustment is needed.

Minimum Tapping Depth [T min ]. Minimum Drilling Depth [G]. Helicoil inserts are diametrically larger than the tapped hole. Plug Tap Bottoming Tap. External threads of this Fine Series have greater tensile stress area than comparable sizes of the coarse series.

Helicoil inserts are diametrically larger than the tapped hole.
