Bolts 12×100 aisi 316 – code: a4-933-12×100 – Osculati

12×100 bolts in AISI 316 stainless steel Osculati (code a4-933-12×100)

I 12×100 bolts in AISI 316 stainless steel Osculati, identified by the code a4-933-12×100 (SKU oscu000001411), are fastening elements designed for those looking for a reference stainless steel bolt in the technical field. The 12×100 size and the configuration at hexagonal head with full threading make them a practical choice for assembly, maintenance, and replacement tasks, where it is useful to work with standard components easily handled with common tools.

The product is associated with the type UNI 5739 / DIN 933, a useful reference for those who need to maintain consistency with project specifications or with bolts already present on board or in the system. In a nautical and plant context, the correct selection of bolts is fundamental: for this reason, it is always advisable to check compatibility with holes, thicknesses, and components to be tightened before installation and keep the code for quick reorders.

Features and construction details

Material: stainless steel AISI 316

These bolts are made of AISI 316 stainless steel, a typical choice when a stainless steel bolt is desired for technical applications, including contexts where the environment can be challenging. Material selection is a central aspect in design and maintenance: it allows maintaining uniformity with other stainless steel components and managing the bill of materials in an orderly manner.

Geometry and type

• Format: 12×100.
• Head: hexagonal, suitable for tightening with common tools.
• , a material commonly used in fittings and small parts for systems. The choice of brass is often linked to the need to use components compatible with other elements of the same material and with typical hydraulic configurations. fully threaded, useful when flexibility is needed in tightening management and pairing with nuts/coupling elements.
• Typological reference: UNI 5739 / DIN 933.

The combination of hexagonal head and full threading is often chosen for processes and interventions where a “standard” and immediately recognizable component is desired, with simple handling in the workshop or on site.

Product identification and supply

• Supplier: Osculati S.r.l.
• Supplier product code: a4-933-12×100.
• SKU: oscu000001411.

For scheduled maintenance activities or spare parts management, always report the code a4-933-12×100 in the onboard documents or plant notes to speed up reorders and replacements, reducing the risk of confusion between similar formats.

Typical applications (nautical and plant engineering)

Stainless steel bolts are often used in multiple points of the system, from fastening mechanical components to supporting accessories and brackets. The 12×100 AISI 316 bolts can be considered when the project or replacement requires exactly this size and stainless steel bolts.

Examples of use

• Assemblies and fittings on structures, brackets, and supports where the use of hexagonal head bolts is foreseen.
• Maintenance and replacement of existing bolts with reference to type UNI 5739 / DIN 933.
• Plant interventions where it is useful to maintain consistency of material (stainless steel) and bolt standard.
• Technical setups and retrofit, when a recognizable and manageable fastening component with common tools is desired.

The choice of the correct bolt always depends on the context: besides the size, it is important to consider how the bolt works together with washers, nuts, and bearing surfaces, and to verify that the assembly is consistent with the installation requirements.

Usage and notes for correct selection

To achieve correct fastening and reduce the risk of errors during installation, it is advisable to set the bolt selection methodically, checking the essential assembly parameters.

Recommended checks before purchase

• Compatibility with holes and with any bolts already installed.
• Overall thicknesses of the components to be tightened, including any washers or plates.
• Pairing with nuts and washers suitable for material and type, based on assembly needs.
• Accessibility for tightening: assess the available space for tools and maneuvering.

Good installation practices

During assembly, it is useful to work with clean surfaces and components in good condition, avoiding forcing threads or incorrect fittings. If the application requires it, consider using appropriate fastening accessories (e.g., washers) depending on the bearing surface and tightening configuration.

Reordering and spare parts management

For quick reorders, refer to the code a4-933-12×100 and the SKU oscu000001411. In professional contexts (construction site, onboard maintenance, plant engineering), noting these references in the bill of materials or intervention log helps maintain continuity between installations and replacements.

Note: the selection of bolts must always be consistent with the specific application. In case of doubts about size or compatibility, it is advisable to compare the existing component or project specification before proceeding.
