Typical applications

The 4 mm Grower washer is used in numerous contexts of hardware and plant engineering, including those related to boating and the installation of components on board. It is recommended whenever working with compatible sized screws and you want to complete the tightening with a support element.

• Maintenance and repairs on small mechanical assemblies.
• Installations of accessories and brackets where appropriate sized bolts are expected.
• Interventions on plants and on-board components (e.g., support fastenings, passages, protections), depending on the project and the screws used.
• Workshop and shipyard: management of small parts for assemblies and replacements.

For a correct choice, it is good practice to verify the compatibility of the washer with the screw/bolt and with the bearing surfaces provided by the assembly.

Advantages during assembly

In a technical context, the use of a Grower washer can offer practical benefits during assembly and maintenance, especially when a more “controlled” tightening and an orderly management of the bolts is desired.

• Tightening support: contributes to completing the coupling between the screw/nut head and the bearing surface.
• Compact solution: suitable for assemblies where space is limited and essential small parts are preferred.
• Standard spare part: common hardware component, useful for restoring existing assemblies without project modifications.
• Simple handling: code RG4 and size mm 4 facilitate reordering and identification.

Usage and operational notes

To achieve a correct assembly, it is recommended to use the Grower washer in combination with screws of the appropriate size and according to the instructions of the assembly or installed component manufacturer. In case of maintenance, it is useful to check the condition of the bolts and replace worn or deformed elements.

• Size check: make sure the washer is suitable for the intended screws (4 mm).
• Surface inspection: verify that the bearing surfaces are clean and suitable for tightening.
• Maintenance: in case of frequent disassemblies, assess the condition of the washer and replace it if necessary.
• Reordering: for requests and stock replenishment, refer to code RG4 and the SKU MOLIN00000066.

If you have doubts about choosing the most suitable small parts for your system or application, it is advisable to compare the size and type with the bolts already installed or with the project's technical bill of materials.
