M6 thread suction cup Rubber suction cups with nut

An M6 thread suction cup with a nut connection is a useful starting point for a fixture that attaches through a matching plate or bracket. The threaded interface allows the mechanical joint to be defined independently of the contact face. For a workable assembly, however, the nut needs suitable access and the plate must sit in the intended position without compressing or twisting the cup unevenly.

Draw the fastening stack from the cup to the outer face of the hardware. Include the bracket thickness, hole size, thread length and any specified washers or locking arrangement. Confirm which hardware is included in the supply and which belongs to the customer's assembly. Also check tool access: a nut that can be reached on a loose sample may become inaccessible after the fixture is placed near an enclosure wall.

Suitable smooth, nonporous surfaces can include sound glass and glazed tile with an uninterrupted area beneath the cup lip. Establish whether the fixture is placed vertically, horizontally or at an angle, and describe how the connected item is handled. These details influence the forces at the cup edge. Retention needs to be checked on the complete bracket assembly rather than judged solely from how firmly the unconnected cup initially adheres.

When installing an M6 thread suction cup, use an assembly sequence that keeps the sealing lip relaxed and free of distortion. Inspect the hardware connection after normal repositioning and confirm that the bracket has not rotated relative to the cup. Keep the contact face clear of swarf or debris from the mounting plate. Release suction before moving the fixture to a new location. For custom production, ETOL can review the rubber body and connection dimensions from the fastening-stack drawing, supported by a sample of the mating bracket and a description of the proposed surface.

Material options

Rubber compound options, customized alongside the profile and contact conditions.

Hardness selection

Solid rubber options: 30–90 Shore A. Retention needs to be checked on the complete bracket assembly rather than judged solely from how firmly the unconnected cup initially adheres.

Custom geometry

Include the bracket thickness, hole size, thread length and any specified washers or locking arrangement.

Fit evaluation

Confirm which hardware is included in the supply and which belongs to the customer's assembly.

Color & OEM

Custom colors; OEM markings outside the suction contact face.
