The product image shows five black threaded pieces with a socket recess. The listing does not give the thread pitch, head dimensions or a compatible cutterhead model.
Compare the I158_03 flat style only when its head shape matches the seat in your cutterhead.
Check fit before use
- Compare the pin with the original part and its seat before installation.
- Confirm the thread pitch and engagement depth with the cutterhead maker.
- Use the correct tool and tightening instructions for the machine assembly.
The page does not identify a material grade or compatible cutterhead. A matching diameter and length do not confirm thread pitch or head clearance. Compare the old pin, its seat and the listed shape before you install a replacement. Keep the old part as a reference. Check that the replacement thread engages the original seat without force.
For an unclear fit, send the machine model and a photo of the holder through the BitsRouter contact page.
