Osculati Auto TS self-tapping screw in AISI 316 stainless steel (4.2×19) – countersunk head

The Auto TS Osculati is a self-tapping screw in AISI 316 stainless steel, offered in the format 4,2×19 and with countersunk head. It is a hardware component designed for those operating in the nautical and onboard installation, where the choice of screws and the correct identification of the spare part are fundamental aspects for orderly and repeatable interventions.

This sheet is structured to help you quickly recognize the item and manage reorders and inventory: the product is identified by the supplier code a4-7982-04.2×019 (SKU oscu000001333) and is indicated by Osculati with references UNI 6955 and DIN 7982.

Product features and details

Material: stainless steel AISI 316

The screw is made of AISI 316, a typical choice for applications where stainless steel fasteners suitable for technical contexts and demanding environments are desired. In the nautical field, attention to material is often crucial to maintain consistency with the rest of the bolting and reduce issues related to non-homogeneous replacements.

Type: self-tapping screw (Auto TS)

It is a self-tapping screw, designed for assembly and fastening in processes where a screw that creates its own thread during screwing is useful. It is a common solution in many installation and maintenance activities, especially when working on onboard components and accessories that require quick and neat interventions.

Format and identification

• Size: 4,2×19
• Head: countersunk
• Supplier code: a4-7982-04.2×019
• SKU: oscu000001333
• References indicated by the manufacturer: UNI 6955, DIN 7982
• Supplier: Osculati S.r.l.

Note: to avoid errors during reordering, it is advisable to always refer to the Osculati code reported in the datasheet, especially when similar screws by size or finish are present in the workshop or onboard.

Countersunk head: when needed

The countersunk head it is typically chosen when a fastening with reduced surface bulk or a more flush fit with the support is desired, compatible with the intended processing. In many accessory and finishing installations, this geometry helps maintain a neat appearance and limit unwanted protrusions.

Typical applications (nautical and plant engineering)

This self-tapping screw can be used in various contexts of maintenance and installation, particularly when stainless steel fasteners of the same family and with clear identification are required. Some recurring usage examples include:

• Onboard fittings and accessories: fastenings on components and small parts where self-tapping screws are expected.
• Maintenance interventions: replacement of existing screws with a consistent spare in terms of material and type.
• Plant engineering and hardware: assemblies on brackets, supports, and small parts when the project or component requires a countersunk and self-tapping head.
• Spare parts management: quick reordering thanks to SKU and supplier code, useful for shipyards, workshops, and technical warehouses.

In case of doubts about the support or hole preparation, it is good practice to check the configuration of the component being worked on and maintain consistency with the fasteners already installed.

Usage and operational notes

Check before installation

Before proceeding, verify that measurement, testa and self-tapping type is consistent with the mounting point and the screw to be replaced. In case of replacement, comparing the removed piece with the new screw helps avoid undesired differences (for example in head geometry or length).

Compatibility with the substrate

The datasheet identifies the product and its family but does not specify the support materials or mounting conditions. For particular applications, it is advisable to follow the indications of the component to be fastened or the internal procedures of the shipyard/workshop.

Regulatory references indicated by the manufacturer

Osculati associates the item with the references UNI 6955 and DIN 7982. If you are replacing existing screws or need to comply with a bill of materials, these references can be useful to align the choice of spare parts with the expected type.

Advice for warehouse and scheduled maintenance

For efficient management, note in the bill or maintenance sheet the code a4-7982-04.2×019 along with the SKU oscu000001333. It is a simple measure that reduces search times and the risk of incorrect orders, especially when managing multiple boats or multiple systems.
