Bolts 5×30 aisi 316 – code: a4-933-05×030 – Osculati

5×30 bolts in AISI 316 stainless steel Osculati (code a4-933-05×030)

I hex head bolts/screws in AISI 316 stainless steel Osculati, in size . In particular, it is suitable for activities such as:, are a bolting solution designed for installations and maintenance where reliable components suitable for technical contexts are required, including those typical of nautics and of the’onboard systems. The product is identified by supplier code a4-933-05×030 and is associated with the SKU oscu000001416, useful for reordering and spare parts management.

The configuration with hexagonal head facilitates tightening operations with common tools, while the full threading makes these bolts versatile in multiple mounting configurations, for example with nuts and washers, or in the presence of variable spacers. The type corresponds to fully threaded hex head screws with reference UNI 5739 / DIN 933 (useful indication at product family and shape level, to be verified based on application needs).

Features and construction details

Material: stainless steel AISI 316

The’AISI 316 is a stainless steel commonly chosen in nautical environments and humid conditions, where bolting is often exposed to demanding conditions. In onboard applications, material choice is a key aspect to maintain assembly quality over time and reduce the need for frequent replacements.

Geometry: hex head

The hexagonal head is one of the most widespread solutions in technical fields because it allows practical and controllable tightening with standard wrenches. It is particularly useful when working in technical spaces, on brackets, supports, plates, or plant components where quick maintenance intervention is important.

Full threading (type DIN 933 / UNI 5739)

The full threading offers flexibility during assembly and allows managing couplings with:

• nuts (for through joints);
• washers (to distribute load and protect surfaces);
• thicknesses and spacers (to adapt the assembly to components with different dimensions).

The reference to DIN 933 and UNI 5739 helps to frame the product family (fully threaded hex screws/bolts), useful when standardizing components already present onboard or in the plant.

Typical applications (nautical and plant engineering)

These AISI 316 stainless steel bolts are suitable for a wide range of technical uses, especially where stainless bolting and a hex head for practical tightening are required. In nautical and plant contexts, they can be used, for example, in:

• onboard maintenance and replacement of existing bolting;
• fastenings on brackets and supports for technical components;
• assemblies with nuts and washers on plates or secondary structures;
• installations where a fully threaded screw/bolt is useful to manage variable thicknesses.

The choice of size and pairing (nut, washer, possible locknut) must always be verified based on the component to be fixed and the mounting conditions.

Usage and operational notes

Checks before installation

Before installation, it is advisable to check:

• sizes and pairings with the hole and with the possible nut;
• material thickness to be joined, to ensure correct tightening;
• compatibility with washers and accessories already present in the assembly.

Good practices in the nautical field

In onboard contexts, where access to components may be limited and environmental conditions can be challenging, it is useful to plan the intervention by preparing tools suitable for the hex head and verifying the availability of nuts/washers consistent with the chosen bolts. For specific or critical applications, always follow the instructions of the plant or component manufacturer to be fixed.

Note on the term “bolts/screws”

In technical and commercial language, these items may be referred to as bolts o screws depending on the use (with nut, in threaded hole, etc.). The type described here is that of fully threaded hex head screws, commonly associated with the family DIN 933 / UNI 5739.
