• Size: mm 8
• Supplier product code: DAA28
• Supplier: F.LLI MOLINO SRL
• SKU: MOLIN00000048

What does “self-locking” mean”

A self-locking nut is designed to offer greater resistance to loosening compared to a standard nut, thanks to an integrated locking system. This feature makes it a common choice in applications subject to vibrations or repeated stresses, where it is useful to keep the tightening more stable.

Format and warehouse management

The nut is a typical spare/consumable to keep in stock in the workshop or on board, useful for assembly and maintenance interventions. Identification through code DAA28 facilitates reordering and material management in professional contexts.

Typical applications

The self-locking nut mm 8 is used in many assembly and maintenance activities, particularly where hardware is an integral part of structures, supports, or components installed permanently or semi-permanently.

Plant engineering and maintenance

• Fastenings on brackets, supports, and plates in plant engineering.
• Routine maintenance interventions where a more “stable” tightening than a standard nut is required.
• Restoration of existing fastenings in the presence of vibrations or micro-movements.

Technical use in the nautical field

In the nautical context and onboard plant engineering, bolts are often used on accessories, supports, and components subject to stresses. A self-locking nut can be chosen as a practical solution to reduce the risk of loosening over time, especially in installations where accessibility for frequent checks is limited.

Use and notes

Size verification

Before purchase or installation, verify that the required size is actually mm 8 and that it is compatible with the screw/bolt and the intended application. In case of replacement, it is advisable to compare the existing nut with the new component to ensure the correct dimensional match.

Installation

For correct assembly, use suitable tools and apply tightening procedures consistent with your application. In technical contexts, it is good practice to check the alignment of components and the condition of the threading before tightening, to avoid damage or incorrect fittings.

Maintenance and inspections

Although a self-locking nut is designed to counteract loosening, in critical applications it is advisable to schedule periodic tightening checks, based on usage conditions and adopted maintenance procedures.
