TS-Optics M4 Knurled Screws for Secondary Mirror Adjustment, Length 45 mm


The set of three knurled screws allows the collimation of the Newtonian secondary mirror without tools.

♦ Continuous M4 thread with 45 mm length

♦ The tip of the thread is face milled to avoid pressure points in the secondary mirror holder.

♦ An unintentional twisting of the secondary mirror during collimation is prevented.

♦ Knurled plastic head with 12 mm diameter, so the screws are also suitable for smaller secondary mirrors
