Special Threads
At BAER we support projects beyond standard specifications. Alongside our core range, we manufacture tools for special thread applications. This category covers metric taper threads, sheet‑metal screw threads, and wood screw threads – all in proven BAER quality.
Everything you need to know about special threads
Special threads address special requirements. The metric taper thread per DIN 158 shares the metric profile but is conical (taper 1:16). It is often used for pipe couplings by combining a tapered external thread with a cylindrical M internal thread; identical profiles make them compatible. Marked with the suffix keg, e.g., M 12 × 1.5 keg.
The sheet‑metal screw thread (per DIN EN ISO 1487, 60°) is common on self‑tapping screws; a pilot hole is still required, and in hard materials the thread is typically pre‑tapped. Designation: ST (sometimes Bl).
The wood screw thread (60°, wide root) is designed for direct screwing into wood. Inserts or special threaded parts are used for highly durable or detachable joints. Designation: H.
Special threads to DIN standards – Our range
Whether for sheet‑metal, wood, or metric taper threads, the BAER online shop offers a wide choice of taps and dies.
Metric taper thread
We supply one‑pass taps (HSSG) for metric taper threads – usable by hand or machine, precise and durable. External threads are produced with round dies that generate the 1:16 taper – ideal for tight pipe connections.
Sheet‑metal screw threads
For internal threads use machine taps made of cobalt‑alloyed HSSE – stable in series production and suitable for many materials. External threads are cut with high‑precision round dies, also guidable by hand with a die stock.
Wood screw threads
No internal tapping is required in wood. To produce screws and studs with wood screw threads, use our round dies – by hand or with machine assistance.
