Bolts 8×70 aisi 316 – code: a4-933-08×070 – Osculati

8×70 bolts in AISI 316 stainless steel Osculati (code a4-933-08×070)

I 8×70 AISI 316 bolts Osculati, identified by the supplier code a4-933-08×070, they are fastening elements designed for technical assemblies where a standard geometry and practical tightening management are desired. The choice of’AISI 316 stainless steel makes them a typically adopted solution in contexts exposed to humidity and in nautical applications, where stainless steel is often preferred for its suitability for use in demanding environments.

The manufacturer classifies them as type UNI 5739 / DIN 933, a useful reference for those who need to integrate or replace bolts while maintaining dimensional and shape criteria consistent with common standards. They are suitable for use with compatible nuts and washers and for fastening on brackets, supports, and onboard plant components.

Features and construction details

These bolts belong to the family of fastenings with hexagonal head, a common configuration because it allows tightening with standard tools and facilitates assembly and maintenance operations. The presence of full threading makes them suitable for multiple coupling configurations, particularly when working with nuts and when it is useful to have threading available along the entire useful part of the shank.

Why the reference to UNI 5739 / DIN 933 is useful

When working on existing systems or creating new assemblies, the reference to a standard (such as UNI 5739 / DIN 933) helps maintain consistency with already present components and simplifies the selection of matched accessories. In technical fields, this often translates into faster selection of nuts, washers, and tools, as well as greater predictability during assembly.

Typical applications (nautical and onboard plant engineering)

In the nautical and plant engineering context, stainless steel bolts are commonly used for fastenings where good environmental resistance and orderly maintenance over time are required. These bolts can be used in many operational situations, especially when working on metal components, brackets, and supports that require reliable tightening with a hexagonal head.

Examples of use

• Brackets and supports for onboard components (technical fastenings and service structures).
• Assemblies with nuts and washers in maintenance or bolt replacement interventions.
• Fastenings on light carpentry and accessory components, where standardized bolts are useful.
• Plant engineering (in a general sense) when a tightening element with a hexagonal head and full threading is required.

Application note

The choice of the correct bolt always depends on the type of material to be clamped, the thickness of the components, and the joint configuration (with nut, with threaded insert, with washers, etc.). If a system already provides a specific type, reference to UNI 5739 / DIN 933 can help maintain continuity with existing bolts.

Usage and notes for selection

For correct assembly, it is advisable to match bolts compatible nuts and washers with the same material family and with dimensions suitable for the application. In the nautical field, the correct selection of fastening accessories contributes to a neater installation and easier maintenance.

Practical indications (without replacing site procedures)

• Check space and accessibility: the hexagonal head requires space for the tool.
• Match suitable washers: useful for distributing the load and protecting contact surfaces (depending on the type of joint).
• Check thread compatibility: especially in case of replacement on existing components.
• Maintenance management: in marine environments it is good practice to periodically inspect fastenings and intervene if necessary.
