Recommendation: STARLOCK is ideal for fast assembly in series production. For applications requiring frequent removal, Seeger rings in grooves are preferable. STARLOCK is mainly for permanent or semi-permanent fastenings.

Frequently Asked Questions about STARLOCK Washers

Everything you need to know about STARLOCK systems

They are pressed onto plain shafts (without grooves). The internal teeth flex during installation, then grip the shaft, creating axial locking. Removal with a flat screwdriver or a dedicated tool.

No, STARLOCK washers are designed for permanent or semi-permanent fastenings. Removal is possible with care (flat screwdriver), but reusing them is not recommended: the teeth deform during assembly and lose effectiveness. For applications with frequent removal, Seeger rings are preferable.

No, that is the main advantage over Seeger rings. STARLOCK is mounted on a plain shaft (Ø with h8-h11 tolerances). No groove is needed, which reduces machining costs and stress concentration on the shaft.

Consider: 1) Shaft diameter (h8-h11 tolerance). 2) Axial load (see permissible load tables). 3) Environment (standard, corrosive, temperature). 4) Removal frequency (standard or reinforced). We assist with selection.

Yes, they are designed for it. The teeth create a mechanical grip on the shaft and resist vibration and shock. For automotive and industrial use, choose reinforced versions or versions with external teeth for greater security.

Yes, we supply STARLOCK in stainless steel (AISI 304, 316), as well as zinc-plated, bronze-finished and with special coatings. Stainless steel for medical, food, marine and chemical environments.

For very high loads: Seeger rings in grooves. If rotational locking is critical: keys or pins. For permanent fastening: welding, adhesive bonding, riveting. Consult our technical department for an assessment.
