BEYOND TR20 Trapezoidal Thread Taps
High-Precision HSS Lead Screw Tapping Solutions | Pitches 2.0mm to 6.0mm
What makes BEYOND TR20 taps ideal for heavy-duty lead screws?
The BEYOND TR20 series comprises professional-grade Trapezoidal Metric Thread Taps designed specifically for creating high-torque transmission threads. Unlike standard triangular threads, the TR profile is engineered for power screws and lead screw applications where high axial force and smooth motion are required. Manufactured from premium High-Speed Steel (HSS), these taps provide exceptional wear resistance and precision in carbon steel, alloy steel, and stainless steel workpieces.

Why should I choose HSS Trapezoidal taps for industrial machining?
- ✅ Straight Flute Design: Optimized for through-hole tapping with maximum tool rigidity to prevent breakage during high-torque cycles.
- ✅ Premium HSS Material: Our taps use advanced metallurgy to maintain cutting edge sharpness under high thermal loads.
- ✅ Precision Ground Geometry: Ensures accurate 30° flank angles for smooth lead screw engagement and low friction.
- ✅ Wide Pitch Availability: From TR20x2 for fine adjustment to TR20x6 for rapid travel power screws.
What are the technical specs for the TR20 series?
| Model | Metric Pitch | Imperial Equiv. | Drill Size (mm) |
|---|---|---|---|
| TR20x2 | 2.0 mm | ~12.7 TPI | 18.1 mm |
| TR20x3 | 3.0 mm | ~8.46 TPI | 17.2 mm |
| TR20x4 | 4.0 mm | ~6.35 TPI | 16.3 mm |
| TR20x6 | 6.0 mm | ~4.23 TPI | 14.5 mm |
Recommended Cutting Parameters
For TR20 threads, slower speeds are essential for accuracy:
- Rotation Speed: 3 - 10 m/min (depending on material hardness).
- Coolant/Lubrication: High-pressure sulfur-based cutting oil is strongly recommended.
- Tapping Method: Rigid tapping on CNC or high-torque radial drills.
Product Applications
Ideal for machining components for industrial valves, 3D printer Z-axis rods, CNC lathe lead screws, and heavy-duty mechanical jacks where power transmission is required.
Machine Compatibility
Fully compatible with standard square-drive tapping chucks, Morse taper adapters, and professional CNC machining centers (VMC/HMC).

Frequently Asked Questions
A: TR threads are Metric Trapezoidal (30° angle). ACME is Imperial (29° angle). While similar, they are not interchangeable. Check your design requirements first.
A: For large TR20 pitches (like 5.0 or 6.0), using a set or pre-boring the diameter accurately is necessary to reduce tool load.
A: Our standard HSS series is bright finish for maximum sharpness. TiN or TiAlN coatings are available for high-volume abrasive material machining.
HSS-E (Cobalt) offers higher heat resistance than standard HSS. Always ensure high-torque lubricant is used to prevent "welding" of chips to the trapezoidal profile.
