Identification

• Product: Double M screw
• Size: 3″
• Supplier product code: 0280M
• Brand / Supplier: Maestrini S.R.L. Sole Proprietorship

Typical applications

The double screw is commonly used as a connecting or fastening element in assemblies where it is useful to have a “double” solution (for example for couplings, fastenings, or connections between parts).

• Routine maintenance of hydraulic systems and fitting components, when it is necessary to replace a worn or missing element.
• Restoration of existing assemblies, maintaining consistency with the manufacturer's codes and components.
• Interventions on technical systems where code-identifiable small parts are required to simplify procurement and spare parts management.

For correct application, it is important to verify the correspondence with the component to be replaced (size, type, and code), as well as compatibility with the assembly in which it is installed.

Checks before purchase

• Check the code: make sure that the requested component corresponds to 0280M.
• Confirm the size: the datasheet indicates 3″; compare with the installed part or with the system's bill of materials.
• Evaluate the mounting context: in the absence of further specifications (materials, threads, standards), it is advisable to rely on the correspondence with the original replacement or on the indications of the designer/maintenance technician.

Installation

The installation of fastening/connecting components in the hydraulic field requires attention to:

• cleaning of seats and mating parts;
• correct alignment of components;
• tightening appropriate to the assembly requirements.

If the application is part of a critical system or subject to specific requirements, it is appropriate to adhere to internal procedures and the technical indications of the system manufacturer.
