Interlocking blocks 12 aisi 316 – code: a4-982-12 – Osculati

High type self-locking hex nuts in AISI 316 (DIN 982) – Osculati

The hex nuts high type self-locking DIN 982 Osculati in AISI 316 stainless steel are a suitable choice for technical fastenings in nautical environments and for onboard systems, where it may be useful to maintain more stable tightening in the presence of vibrations and stresses. This item is identified by the supplier product code a4-982-12 and relates to the size 12.

The “tall type” format is often preferred when a more complete thread engagement is desired, particularly on assemblies subject to maintenance, refitting, or interventions on supports and brackets. The use of AISI 316 stainless steel makes it consistent with installations exposed to humidity and marine atmosphere, typical of the onboard environment.

Product features and details

Type: high type self-locking (DIN 982)

It is a self-locking in execution high type, hex nut, compliant with DIN 982 type. In practical applications, this configuration is chosen when a tightening that remains more stable over time is preferred, especially on components that may be subject to micro-movements or vibrations.

Material: stainless steel AISI 316

The nut is made of AISI 316 stainless steel, a material commonly used in nautical hardware for its suitability in humid and marine contexts. It is a suitable solution when you want to maintain material consistency on onboard systems and assemblies, reducing typical issues of aggressive environments.

Identification and traceability

• Supplier: Osculati S.r.l.
• Supplier product code: a4-982-12
• Size: 12

This information facilitates alignment with bill of materials, spare parts, and maintenance procedures, especially when working on multiple fastening points or scheduled interventions.

Typical applications in nautical and onboard systems

Stainless steel self-locking nuts are frequently used in installations where the fastening must remain reliable even in the presence of vibrations, shocks, or load cycles typical of use in navigation. This model is suitable for assembly and maintenance on components exposed to moisture or marine atmosphere.

Examples of use

• Brackets and supports for onboard accessories and technical components.
• Mechanical assemblies where it is useful to limit loosening due to vibrations.
• Refitting interventions and hardware replacement on existing systems.
• Fastenings in damp areas or subject to splashes, where stainless steel hardware consistent with the environment is preferred.

The choice of a self-locking nut is particularly common when one does not want to rely exclusively on additional locking systems, or when a neat and repeatable solution is desired during assembly.

Usage and operational notes

Size selection and thread verification

This item is in size 12. Before purchase and assembly, it is advisable to verify compatibility with existing bolts (thread and dimensional compatibility), especially when replacing on already installed systems.

Good assembly practices

• Ensure that the bearing surfaces are clean and in good condition.
• Tighten evenly, avoiding unnecessary force.
• In case of periodic maintenance, visually check the fastening and the general condition of the hardware.

In nautical contexts, periodic checking of fastenings is a common practice, especially on components subject to vibrations or exposed to atmospheric agents.

Note on combinations and replacements

To maintain consistency and ease of maintenance, it is often preferable to match these nuts with stainless steel bolts and washers of the same material family. If working on a refitting, evaluating the uniformity of the existing hardware can simplify spare parts management and control procedures.
