I158_01 is a replacement insert pin listing. The title and option specify 7 mm length, 4 mm diameter and a pack of five. The single gallery image shows five black threaded pins with round heads. The page does not map this pin size to a specific cutterhead or insert holder, so compare the dimensions with the part being replaced.

Match the pin dimensions to the holder

Compare the 7 mm length and 4 mm diameter with the pin being replaced and the holder drawing. Check the threaded section, head shape and seating surface as well. The listing does not provide a cutterhead compatibility chart, so size alone cannot confirm fit.

Before replacing a pin

Measure the old pin length and diameter.
Compare its thread and head shape with the gallery and holder drawing.
Confirm that the package quantity of five suits the replacement task.
Follow the cutterhead maker’s procedure for removal and installation.

Listing limits

The page names no compatible cutterhead, thread pitch, material grade or tightening value. Its image shows five threaded pins but gives no separate technical drawing. Use the listed dimensions as a first check and confirm the thread and seating details with the holder documentation before ordering.
