Bolts 8×50 aisi 316 – code: a4-933-08×050 – Osculati

Bolts 8×50 in AISI 316 stainless steel Osculati (code a4-933-08×050)

I bolts 8×50 in AISI 316 stainless steel Osculati, identified by the code a4-933-08×050, are fastening elements designed for those working in the nautical and onboard systems field who seek common stainless bolts suitable for installations and maintenance interventions. These are bolts with a hexagonal head with full threading, belonging to the family UNI 5739 / DIN 933, a common and practical type to manage both in the workshop and in the warehouse.

The choice of’AISI 316 is typical when the application involves exposure to humidity and external agents and a stainless steel solution is desired to reduce issues related to oxidation compared to non-stainless materials. In contexts such as onboard, where fastenings are often subject to variable environmental conditions, having stainless bolts is a frequent requirement to maintain consistency and reliability of the assembly.

Features and construction details

These bolts belong to the category of hex head fasteners, a common choice for assemblies requiring tightening with standard tools and ease of inspection. The fully developed threading makes them suitable for many coupling configurations, especially when working with nuts and washers and flexibility in managing component thickness is desired.

Key product points

• Type: hex head bolt, full thread.
• Reference standard: family UNI 5739 / DIN 933 (as an indication of shape and product standard).
• Material: AISI 316 stainless steel.
• Format: 8×50 (as per product denomination).
• Supplier: Osculati S.r.l.
• Supplier product code: a4-933-08×050.

The reference to UNI 5739 / DIN 933 is also useful during reordering or replacement: it allows easier orientation in choosing equivalent components by geometry and intended use, maintaining consistency with the bolts already present on the system or setup.

Typical applications in nautical and onboard systems

The 8×50 size is a common cut for assemblies and replacements, and the hex head facilitates interventions even when working in technical spaces or areas where access is not always convenient.

• Ordinary and extraordinary maintenance: replacement of existing bolts on brackets, supports, and onboard components.
• Installations and retrofits: mounting accessories and components on structures or plates, when stainless steel bolts are preferred.
• General mechanical assemblies: joining parts with nut and washer, in configurations where full threading is useful.
• Plant engineering: fastening on supports and service frames, where exposure to moisture and external agents suggests the use of AISI 316.

As with any fastening element, the final choice depends on the project and the actual installation conditions. In case of replacement, it is good practice to verify that geometry and dimensions are consistent with the removed component and the available space.

Usage and notes for consistent assembly

To achieve a correct and consistent fastening with the application, it is advisable to pay attention to the matching of components and installation conditions. In particular, in the nautical field it is common to work on different materials (metal, composites, wood, painted supports) and in areas subject to vibrations or humidity cycles: for this reason, it is useful to set up the assembly with criteria, without improvisation.

Operational advice (general)

• Matching with compatible nuts and washers: for an orderly and functional assembly, use components consistent in threading and material, based on assembly needs.
• Check the clearances: before installation check available space for hex head, possible washer, and tool access.
• Replacement check: if the bolt replaces an existing element, verify that the length and configuration are adequate for the clamping pack (overall thicknesses).
• Warehouse management: keep the reference to the code a4-933-08×050 helps reduce picking and reordering errors.

If the application is critical or subject to specific requirements, it is advisable to refer to the indications of the system or component manufacturer being worked on, and choose bolts consistent with the project.

Summary

I 8×50 AISI 316 bolts Osculati (code a4-933-08×050) are a practical solution for hex head fastenings with full threading, in a type attributable to UNI 5739 / DIN 933. Ideal for maintenance and installations in the nautical and onboard plant field, they represent a commonly used component when stainless steel bolts are desired for contexts exposed to moisture and external agents.
