Bolt 12x60aisi 316 – code: a4-933-12×060 – Osculati

The Bolt 12×60 AISI 316 Osculati (code a4-933-12×060) is a stainless steel fastener designed for technical assemblies where reliability, installation order, and ease of maintenance are required. It is a typical solution for’onboard systems and for applications where it is preferred to use stainless steel bolts in line with already existing components.

The geometry at hexagonal head and the full threading makes it suitable for many assembly configurations, especially when working with nut and washers and when thicknesses may vary. The classification UNI 5739 / DIN 933 also helps maintain consistency with bolt standards commonly used in technical fields.

Features and construction details

This bolt belongs to the family of fully threaded hex head bolts, a type widely used for general fastening and targeted replacements on existing systems. The choice of’AISI 316 is typical when a stainless steel fastener suitable for demanding contexts, such as nautical and plant engineering, is desired.

Type: hex head, full threading

• Hex head: facilitates tightening and loosening operations with common tools, useful in maintenance and quick interventions.
• Fully threaded: offers flexibility in assemblies with variable thicknesses and in configurations with nuts, locknuts, and washers.
• “Assembly” setting”: suitable for brackets, supports, and fastenings where it is important to be able to adjust the position or stop using nut/washer.

Material: stainless steel AISI 316

The’AISI 316 stainless steel is a common choice in nautical and technical onboard applications. In particular, it is often preferred when uniformity with other already installed stainless steel bolts is desired and when the usage environment requires materials suitable for marine or humid contexts.

Standard references: UNI 5739 / DIN 933

The classification UNI 5739 / DIN 933 identifies the type of bolt (hex head with full threading). This reference is useful for:

• quickly recognizing the component family during replacement;
• maintaining consistency with bolts already present on brackets, supports, and accessories;
• simplifying the choice of compatible nuts and washers in a traditional assembly.

Product code and identification

For orderly management of purchases and spare parts, the product is identified by:

• Brand / supplier: Osculati S.r.l.
• Supplier code: a4-933-12×060

In professional contexts (shipbuilding, maintenance, refitting), the code is particularly useful for reorders and to maintain uniformity among installed components.

Typical applications (nautical and plant engineering)

The fully threaded hex head bolt is a “cross-cutting” component, used in many situations where mechanical fastening with nut and washers is performed. In nautical and onboard plant engineering, it can be practically used for assembly and replacement interventions on non-structural elements and accessories.

Assemblies with nut and washers

• assemblies on staffe and supports;
• fastenings on plates or connecting elements where a “through” nut is used;
• installations where it is useful to adjust the tightening and position using washers and nuts.

Consistent maintenance and replacements

When working on existing systems or accessories, choosing a bolt that conforms to the type DIN 933 / UNI 5739 helps maintain a replacement consistent with the existing bolting. The hex head also makes ordinary and extraordinary maintenance operations easier.

General fastenings in onboard environments

On boats and in engine rooms, stainless steel bolts are often used for general fastenings on accessories, cable trays, supports, and system components. This bolt is suitable for such uses when the design or installation requires a solution with nut and washers and an extended thread along the shank.

Usage and purchase notes

For correct assembly, it is good practice to always check compatibility with existing components (nut, washers, any holes and thicknesses). In case of replacement, the reference DIN 933 / UNI 5739 helps identify the type, while the Osculati code a4-933-12×060 is useful for reorders and spare parts management.

Operational guidelines (generic)

• Use nut and washers appropriate to the type of assembly expected.
• During maintenance, check the condition of the bolts and replace worn or no longer suitable components.
• To maintain uniformity on the system, consider using bolts of the same family and material.

Note

The datasheet describes the product based on the available information (type, material, standard references, and code). For specific project needs or particular applications, it is advisable to verify the specifications required by your assembly.
