Bolts 6×30 aisi 316 – code: a4-933-06×030 – Osculati

6×30 bolts in AISI 316 stainless steel Osculati (code a4-933-06×030)

I 6×30 bolts in AISI 316 stainless steel Osculati, identified by the code a4-933-06×030, are fastening components designed for technical assemblies where stainless steel hardware is required, typically in contexts of nautics and onboard systems. The choice of AISI 316 is common when the installation takes place in humid or marine environments and a material suitable for such conditions is desired, without giving up a practical solution for maintenance and replacements.

These bolts fall into the category with hexagonal head and fully threaded threading, with reference to shape standards such as UNI 5739 / DIN 933. The 6×30 size makes them suitable for multiple general uses on brackets, supports, and accessories, combined with compatible nuts and washers according to project needs.

Features and construction details

Material: AISI 316 stainless steel

The bolt is made of AISI 316 stainless steel, , a common choice in the nautical field and in applications where the hardware is exposed to moisture, splashes, or marine atmospheres. In a technical e-commerce, AISI 316 is often preferred when you want to standardize the onboard hardware with a material suitable for demanding conditions.

Geometry: hex head

The hexagonal head is a classic configuration for tightening with common tools. It is recommended when a solid and easily inspectable fastening is desired, with the possibility to intervene in maintenance even in technical spaces, depending on the accessibility of the mounting point.

Threading: fully threaded

The fully threaded threading makes the bolt versatile in many mounting situations, especially when the thickness of the components to be joined or the position of the nut require a threaded portion along the entire useful length. This characteristic is typical of the family UNI 5739 / DIN 933, referred to as a type reference.

Product identification: Osculati a4-933-06×030

The supplier product code a4-933-06×030 allows quick identification during reorder, spare parts management, and bill of materials compilation. In the nautical field, where component standardization simplifies interventions, the reference to code and supplier helps maintain consistency between installations and replacements.

Typical applications (nautical and plant engineering)

These bolts can be used in numerous general fastening contexts, particularly where stainless steel hardware is used for consistency with the working environment and other components installed onboard.

Assemblies on brackets, supports, and accessories

• Fastening of staffe and supports for technical components.
• Mounting of accessories and small parts on structures or panels, when provided by the project.
• Localized maintenance and replacement of existing bolts with stainless steel equivalents.

Uses in humid or marine environments

In installations exposed to moisture or contact with marine atmosphere, stainless steel bolts are often chosen for uniformity and ease of management. AISI 316 is commonly associated with these contexts, especially when a solution consistent with nautical use is desired.

Usage and installation notes

Matching with compatible nuts and washers

For correct assembly, it is advisable to match the bolt with compatible nuts and washers with the threading and material chosen for the installation. The selection of fastening accessories depends on the type of support, bearing surfaces, and project requirements (for example, presence of vibrations, need to distribute load, surface protection).

Material consistency

In plant engineering and nautical applications, it is good practice to maintain consistency between the materials of the bolts and those of the paired elements, evaluating case by case based on usage conditions. If the application involves pairings with different metals or particular conditions, the choice of small parts and accessories must be defined according to the project and installation procedures adopted.

Dimensional check before ordering

The size 6×30 identifies the size of the bolt; before purchase, it is appropriate to verify that it is the one required by the assembly (thicknesses, encumbrances, accessibility for tightening) and that the type UNI 5739 / DIN 933 is consistent with the component to be replaced or with the project specification.

Maintenance instructions

• Periodically check the tightening according to the maintenance procedures of the system or the boat.
• In case of replacement, use equivalent components in type and size, maintaining the code reference for correct identification.
• Consider the use of appropriate washers when working on surfaces that require protection or better distribution of the support.
