Interlocking blocks 6 aisi 316 – code: a4-982-06 – Osculati

Self-locking nuts in AISI 316 stainless steel (size 6) – Osculati

I high type DIN 982 self-locking hex nuts in AISI 316 stainless steel are a typical choice when a reliable and neat fastening is desired in contexts where vibrations and stresses can affect the maintenance of the tightening. This Osculati S.r.l. item, identified by the code a4-982-06, is designed for use in nautical and onboard plant engineering fields, as well as for general maintenance applications where stainless steel components are used.

The presence of the reference to the standard DIN 982 helps in spare parts management and in choosing the correct component within a screw assortment structured by standards. As always, it is important to verify the size correspondence with screws or studs and with the specific needs of your assembly before installation.

Product features and details

Type: high type self-locking hex nut

It is a self-locking nut in execution high type, compliant with the product family identified as DIN 982. This type is commonly used when you want to reduce the risk of nut loosening over time, especially in the presence of vibrations or micro-movements of the assembly.

Material: stainless steel AISI 316

The nut is made of AISI 316 stainless steel, material frequently chosen in nautical and plant engineering for its suitability in demanding environments. The use of stainless steel screws is often preferred when material consistency with other fastening components and good oxidation resistance under typical onboard conditions are desired.

Size 6

The indicated measurement is 6. For correct assembly, always check compatibility with the screw or stud used and with the available thicknesses/clearances in the installation area. In case of doubt, it is advisable to compare the size with existing screws or with the plant's bill of materials.

Identification and codes

• Manufacturer/Supplier: Osculati S.r.l.
• Supplier product code: a4-982-06
• Standard reference: DIN 982

The reference to code a4-982-06 is useful for reorders, spare parts management, and alignment with technical catalogs.

Typical applications

These self-locking nuts are suitable for applications where it is useful to maintain tightening over time and where stainless steel screws are used. In nautical and onboard plant contexts, they can be used in many assembly and maintenance situations, for example on brackets, supports, accessory fastenings, and components that may be subject to vibrations.

Nautical field and onboard systems

• Assemblies and maintenance on onboard components and accessories.
• Fastenings on structures or supports where vibrations or stresses are present.
• Restoration interventions and spare parts replacement with stainless steel screws.

General maintenance and assemblies

• Mechanical assemblies requiring a self-locking nut.
• Applications where a component traceable to a standard (DIN) is desired to simplify material management.

Usage and installation notes

To achieve a correct and consistent assembly with the application, it is advisable to follow some general good practices, adapting them to the specifics of your plant and the assembly manufacturer's instructions.

Compatibility check

• Check the measurement of the nut (6) and the correspondence with screw/stud.
• Check the overall size of the high type is compatible with the available space.
• If you are replacing an existing component, compare type and standard (DIN 982) to maintain uniformity.

Assembly and maintenance

• Make sure the bearing surfaces are clean and the thread is in good condition.
• In nautical contexts, plan periodic tightening checks as part of regular maintenance, especially on components subject to vibrations.
• For interventions on critical systems or structures, evaluate tightening procedures and criteria appropriate to your project.

Important note

Before installation, always verify that the choice of the self-locking nut is suitable for the type of fastening and the expected operating conditions. In case of doubt, it is preferable to compare the component with the existing screws or with the technical documentation of the system.
