8 aisi 316 self-locking nuts – code: a4-982-08 – Osculati

Self-locking nuts size 8 in AISI 316 stainless steel Osculati (DIN 982)

High type hexagonal self-locking nuts DIN 982 in AISI 316 stainless steel are a practical choice when a more stable fastening than a standard nut is desired, especially in the presence of vibrations and stresses typical of onboard installations. This Osculati item, size mm 8, is designed for hardware and plant engineering applications where fastening reliability is an important requirement and where the use of materials suitable for the marine environment is a priority.

The product is identified by the supplier code a4-982-08 (SKU: oscu0000001554) and is offered for integration in assemblies and maintenance in nautical and plant engineering fields, maintaining a technical approach consistent with the most common fastening standards.

Features and construction details

These self-locking nuts belong to the family of “high type” hexagonal nuts according to DIN 982. The choice of a self-locking nut is recommended when you want to reduce the risk of loosening over time, without necessarily resorting to additional solutions (such as external locking systems), depending on the project and the adopted assembly procedures.

Material: stainless steel AISI 316

The’AISI 316 is commonly used in hardware intended for exposed and marine environments. In nautical contexts, it is often preferred for its suitability for use in conditions where humidity and salt can stress metal components. The choice of material is therefore consistent with installations on deck, in lockers, in the engine room, or in technical areas where resistance to external agents is a factor to consider.

Format and standards

• Type: high type self-locking hex nut
• Regulation: DIN 982
• Size: mm 8
• Osculati Code: a4-982-08

The standard DIN 982 helps maintain consistency in the selection of fastening components, facilitating replacement and integration in existing assemblies. In technical contexts, having regulatory references is useful to simplify spare parts management and scheduled maintenance.

Typical applications (nautical and plant engineering)

In nautical and onboard plant engineering, self-locking nuts are used in many situations where a traditional fastening may be subject to loosening due to vibrations, load cycles, or micro-movements. The size mm 8 is common in brackets, supports, and hardware assemblies, making this component a useful spare part both for new installations and maintenance interventions.

Examples of use

• Onboard hardware: assemblies and fastenings on structures, supports, and accessories where stable tightening is required.
• Plant engineering: mountings on brackets and supports of technical components, in areas subject to vibrations or stresses.
• Maintenance and refitting: replacement of existing nuts with a self-locking solution, when provided by the project or intervention procedures.

Choosing a self-locking nut is particularly sensible when access to the fastening point is difficult or when you want to reduce the need for frequent checks, always respecting good installation practices and the scheduled periodic inspections.

Usage and operational notes

To achieve correct fastening, it is important that the nut, bolt/screw, and bearing surfaces are compatible and in good condition. In nautical contexts, where exposure to external agents can accelerate wear, it is advisable to pay attention to cleanliness, thread condition, and correct mating of components.

General installation instructions

• Size check: make sure that the size mm 8 is consistent with the bolts used and the assembly design.
• Thread check: avoid use on damaged or dirty threads; a well-maintained thread helps achieve regular tightening.
• Proper tightening: apply procedures and tightening torques provided by the installation (if available) and use suitable tools.
• Periodic inspection: in applications subject to vibrations or variable loads, provide checks according to maintenance practices.

Notes for marine context

In marine environments, the choice of the’AISI 316 is common for exposed hardware. To maintain fastening efficiency over time, it is good practice to evaluate the entire system (paired materials, operating conditions, accessibility, and maintenance). If the application is critical or subject to specific requirements, it is advisable to follow the instructions of the plant manufacturer or designer.
