Bolts 5×50 aisi 316 – code: a4-933-05×050 – Osculati

Bolts 5×50 AISI 316 Osculati (code a4-933-05×050)

I 5×50 bolts in AISI 316 stainless steel Osculati, identified by the supplier code a4-933-05×050, , are a bolting solution designed for fastening and assembly in technical fields. They belong to the family of fully threaded hex head screws/bolts, with reference UNI 5739 / DIN 933, a very common type for maintenance, replacement, and installation interventions where it is important to maintain material consistency and hardware standards.

The configuration with hexagonal head facilitates tightening with common tools, while the extended threading offers flexibility when combined with nuts and washers, adapting to various assembly needs typical of nautical and onboard plant engineering.

Features and construction details

Material: stainless steel AISI 316

The bolt is made of AISI 316 stainless steel, a material frequently chosen in contexts where stainless steel bolting is required for technical applications, including those in nautical environments. The choice of material allows maintaining uniformity with other stainless steel hardware already present onboard or in the plant, simplifying spare parts management and component consistency.

Geometry and standard: hex head, full threading

These bolts belong to the category DIN 933 / UNI 5739: these are bolts with hexagonal head and threading along the entire useful length. This configuration is practical when greater freedom of nut positioning is desired or when the thickness of the components to be joined may vary.

Product identification

• Brand / supplier: Osculati S.r.l.
• Supplier code: a4-933-05×050
• Type: hex head bolt/screw, fully threaded (UNI 5739 / DIN 933)
• Format: 5×50

Note: to maintain maximum consistency during ordering and restocking, it is recommended to refer to the Osculati code as well as the description.

Typical applications (nautical and plant engineering)

Hex head stainless steel bolts are commonly used in many onboard operations and plant engineering, especially when a removable and inspectable fastening is desired. The 5×50 size and full threading make these bolts suitable for interventions where it is useful to adjust the coupling with nuts and washers depending on the assembly.

Examples of use

• Maintenance and replacements of existing hardware, maintaining AISI 316 stainless steel material.
• Assemblies of components and brackets where a hex head is preferred for tightening with standard wrenches.
• Technical installations in nautical and onboard plant engineering, where bolting must be easily available and manageable as spare parts.
• Fastening with nut and washer when flexibility in tightening is needed thanks to the extended threading.

In general, this type of bolt is suitable when a simple, standardized, and practical solution is desired for assembly and disassembly during inspection and maintenance activities.

Usage and operational notes

Matching with nuts and washers

For correct assembly, these bolts are normally used in combination with nuts and, when necessary, with washers. The choice of accessories depends on the application and the type of surface to be clamped. In case of replacement, it is good practice to check the condition of existing components and consider renewing nuts and washers to maintain a clean and functional fit.

Checks before ordering

• Check that the format 5×50 is consistent with the fastening to be made or replaced.
• Check the type requested (hex head, full threading) in relation to the available space and access with tools.
• Refer to the code a4-933-05×050 for unique identification of the Osculati product.

Good maintenance practices

In nautical and plant engineering fields, where interventions can be periodic, it is useful to maintain standardized and easily recognizable bolting. The adoption of a type like DIN 933 / UNI 5739 simplifies spare parts management and makes replacement more immediate if necessary.
