Nuts 12 aisi 316 – code: a4-934-12 – Osculati

AISI 316 Hex Nut Osculati (code a4-934-12)

The hex nut in AISI 316 stainless steel Osculati, identified by supplier code a4-934-12, is a small hardware component designed for those working in the nautical field and onboard systems who want to maintain material consistency and simplicity in spare parts management. The indicated size is 12, useful for maintenance, installation and replacement interventions on compatible bolted fastenings.

In a technical context, the choice of a nut is not only about the “closure” of the fastening: it affects the repeatability of interventions, the standardization of stocks, and the possibility of quickly finding the correct replacement. For this reason, besides the material, it is important to be able to refer to recognizable codes and standards. This item is associated with the standards UNI 5588 and DIN 934, useful indications for identification and alignment with equivalent components during procurement.

Features and details

Material: stainless steel AISI 316

The nut is made of AISI 316, a frequent choice in nautical applications and environments where stainless steel small hardware is preferred for material uniformity and maintenance convenience. When replacing or expanding a system, maintaining the same material on bolts and accessories helps manage components more orderly and reduces the risk of inconsistent pairings.

Shape and reference standards

It is a hex nut, common shape for tightening and loosening with standard tools. The item is indicated as compliant with the standards UNI 5588 / DIN 934, useful references for those working with technical bills of materials, specifications, or maintenance procedures requiring components identifiable according to widespread norms.

Product identification and useful codes

• Supplier: Osculati S.r.l.
• Supplier product code: a4-934-12
• Internal SKU: oscu0000001854
• Indicated size: 12

For reorders, warehouse management, and traceability, it is advisable to use both the SKU and the Osculati code. This approach simplifies alignment between internal documentation, orders, and spare parts, especially when managing multiple suppliers or product lines.

Typical applications (nautical and onboard plant engineering)

This hex nut is suitable for general fastening uses in technical fields, where compatible bolts or threaded rods are used and stainless steel small hardware is desired. In particular, it finds application in activities such as:

• Routine maintenance on assemblies and brackets present onboard.
• Replacements of worn or missing nuts on existing fastenings, maintaining material consistency.
• Installations of accessories and components on supports, plates, and brackets, when the project requires stainless steel bolts.
• Onboard systems (supports, fastenings, light carpentry), where standardized small hardware facilitates future interventions.

When choosing, it is good practice to verify compatibility with the existing bolts (thread and fit), to ensure correct tightening and more straightforward maintenance over time.

Usage and operational notes

Check compatibility before installation

Before assembly, check that the size 12 and the nut threading are consistent with the intended or already installed bolts. In case of replacement, it is advisable to compare the removed component with the new nut to maintain continuity in fastening.

Good maintenance practices

• Visual inspection of the nut and the bolt/bar threading: any damage can compromise tightening.
• Material consistency in fastening: when possible, keep the same material family on nut and bolts for a more organized management.
• Traceability: note in the parts list or intervention report the code a4-934-12 and/or the SKU oscu0000001854 to facilitate future reorders.

Instructions for orders and spare parts

To ensure correct product identification, use in order the Osculati code a4-934-12. For internal needs (warehouse, picking, management integrations), also refer to the SKU oscu0000001854. This double indication is particularly useful when managing multiple similar items by shape and material.
