Bolts 4×40 aisi 316 – code: a4-933-04×040 – Osculati

4×40 bolts in AISI 316 stainless steel Osculati (code a4-933-04×040)

I 4×40 bolts in AISI 316 stainless steel Osculati are a bolting solution designed for and and for typical work in the’onboard systems, where it is important to maintain material consistency and continuity with the bolts already installed. The reference Osculati a4-933-04×040 allows clear identification of the spare part, useful both during maintenance and when managing reorders and scheduled replacements.

Main features and details

Material: stainless steel AISI 316

The bolt is made of AISI 316, a frequent choice in nautical and plant engineering contexts when stainless steel bolts are desired to be used consistently with other metallic components on board. The use of a consistent material helps maintain uniformity in assembly and spare parts management.

Format 4×40

The wording 4×40 identifies the bolt size. In practical applications, this type of measurement is often selected for fastening accessories and small parts, where it is necessary to respect existing holes and dimensional constraints of the component. Before installation, verify that the size is compatible with:

• diameter of the holes and components to be paired;
• overall thicknesses to be tightened;
• any seats for washers and nuts;
• available space for installation and for the tool.

Product code and spare part identification

The reference Osculati a4-933-04×040 is useful for quickly recognizing the product and reducing ambiguity during reordering. In maintenance contexts, being able to recall a unique code facilitates the management of the bill of materials and alignment with the bolts already used.

Typical applications (nautical and plant engineering)

These bolts can be used in many situations where mechanical fastening with small stainless steel bolts is required. In nautical and onboard plant engineering, they are among the useful spare parts for routine interventions and targeted replacements.

Onboard hardware and accessories

• fastening of small accessories and hardware components;
• assemblies on brackets and supports;
• restoration of existing fastenings with stainless steel bolts.

Maintenance and bolt replacement

• replacement of worn or no longer suitable bolts;
• interventions on components requiring material consistency (stainless steel on stainless steel);
• spare parts management with Osculati reference for faster reorders.

Plant engineering and brackets

• light brackets and fastenings on plant components;
• assemblies where it is necessary to respect pre-existing measurements and holes;
• technical assemblies in confined spaces.

Usage and selection notes

Check compatibility before installation

Before proceeding with purchase and installation, it is good practice to verify the compatibility of the 4×40 with the specific application. In particular:

• check that the size matches that required by the component;
• verify compatibility with the drillings accessibility for future maintenance;
• assess the total thickness of the parts to be clamped;
• ensure there is enough space for installation and possible tightening.

Matching with nuts and washers

For a complete assembly, plan to pair with nuts and washers suitable for material and size. Choosing the correct accessories helps achieve a neat and consistent fastening with the assembly.

Maintenance and reorder instructions

In case of replacing existing bolts, it may be useful to note the product code and keep it in the onboard documentation or spare parts list. This simplifies any reorders and reduces the risk of selecting incorrect sizes.

Summary

• Product: Bolts 4×40
• Material: AISI 316 stainless steel
• Code: Osculati a4-933-04×040
• Category: Hardware / Plumbing and hardware

Note: if you need to replicate an existing fastening, always compare size and configuration with the removed bolt or with the specifications of the component to be clamped.
