Stainless steel ball cup, 13 mm ball, 40 mm centre, M10 × 1.5 thread, external clip

Stainless steel ball cup for a 13 mm ball, 40 mm centre distance and M10 × 1.5. thread with an outer retaining clip.

It is the articulated end fitting of the gas spring: it clips onto a ball stud of the same diameter and lets the assembly pivot as the lid or tailgate opens.

Two dimensions have to match. The 13 mm ball diameter must be the same as the stud it mounts on, or the cup will not clip on. The M10 × 1.5. thread goes onto the gas spring rod and belongs to the 14/28 series. The 40 mm centre distance sets how far the pivot sits from the rod end.

Ball: 13 mm · Centre: 40 mm · Thread: M10 × 1.5.
