Interlocking blocks 4 aisi 316 – code: a4-982-04 – Osculati

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

I high type hexagonal self-locking nuts Osculati in AISI 316 stainless steel are a reliable choice for technical fastenings where it is important to reduce the risk of loosening over time. This version is made of size 4 and is offered as a component for new installations or as replacement in the nautical and onboard plant engineering field, where vibrations and stresses can affect the tightness of threaded connections.

The product is identified by the supplier code a4-982-04 (Osculati S.r.l.) and is intended for use in combination with compatible screws or threaded rods, maintaining a correct and consistent assembly approach according to the application requirements.

Features and construction details

Type: “high type” self-locking nut”

These nuts belong to the family of self-locking, designed to provide resistance against loosening caused by vibrations and micro-movements typical of many technical applications. The high type configuration is often chosen when a component with geometry suitable for fastenings where tightening stability is an important requirement is desired.

Material: stainless steel AISI 316

The’AISI 316 is a stainless steel commonly used in nautical and plant engineering for its suitability in contexts where good corrosion resistance is sought. It is a recurring solution for hardware and onboard components, especially when the fastening is exposed to humid environments or harsh conditions typical of marine use.

Reference standard: DIN 982

The product is indicated as compliant with DIN 982, , a widely recognized standard for this type of nut. The presence of a regulatory reference facilitates the identification of the component and integration into fastening systems already set on equivalent technical standards.

Product size and identification

• Size: 4
• Supplier product code: a4-982-04
• Supplier: Osculati S.r.l.

For a correct choice, it is good practice to verify compatibility with the threading of the screw or threaded rod planned in your assembly, as well as the space and accessibility requirements during assembly.

Typical applications (nautical and onboard plant engineering)

These self-locking nuts are suitable for multiple uses where threaded connections are employed and a solution oriented towards tightening stability is desired. In the nautical and technical fields, they are often chosen for maintenance, refitting, and installations on onboard systems and accessories.

Examples of use

• Hardware and accessories: fastenings on components that may be subject to vibrations or stresses during navigation.
• Plant engineering: assemblies and brackets where it is useful to maintain tightening over time, compatible with the system design.
• Maintenance and spare parts: replacement of existing nuts with an equivalent component to restore fastening in an orderly and consistent manner.

The choice of a self-locking nut is particularly sensible when access to the fastening point is not immediate and it is desired to limit the need for frequent control and restoration of tightening, always respecting the prescribed maintenance procedures.

Usage and operational notes

To achieve reliable fastening, it is important that the nut is used correctly and with compatible components. Below are some general indications, useful during selection and assembly.

Compatibility with screws and threaded rods

• Verify that the size 4 it must be consistent with the threading of the male component (screw or threaded rod) planned.
• Ensure that the bearing surfaces are clean and in good condition to avoid irregular tightening.
• In case of replacement, compare the removed nut with the new component to confirm type and dimensions.

Good assembly practices

• Tighten with appropriate tools and with a procedure consistent with the application (without unnecessary force).
• When the fastening is part of a larger system, follow the instructions of the system or accessory manufacturer.
• Schedule periodic checks at points subject to vibrations, especially after maintenance interventions or changes to the setup.

Note on selection and procurement

This item is identified by the code a4-982-04 Osculati: a useful reference for quick reorders, spare parts management, and alignment with bills of materials. If you are working on an existing system, recording the code in technical documentation or maintenance sheets can simplify future interventions.

In summary: a hexagonal nut high type self-locking in AISI 316, with reference DIN 982, designed for technical fastenings in the nautical and plant engineering fields, in the size 4 and with supplier code a4-982-04.
