Auto ts 2.9×19 aisi 316 countersunk – code: a4-7982-02.9×019 – Osculati

Self-tapping screw Auto TS Osculati in AISI 316

The Auto TS 2.9×19 Osculati is a self-tapping screw in AISI 316 stainless steel, designed for assembly and maintenance interventions where direct fastening is needed without having to create a pre-thread in the support. It is a typical solution in the field of nautical and onboard installation, useful when working on components, accessories, and small parts that require reliable screws consistent with the standards commonly used in the sector.

The product is identified by the supplier code a4-7982-02.9×019 and is indicated by the manufacturer in the family UNI 6955 / DIN 7982. This information is particularly useful when a “like-for-like” replacement must be made or when continuity with the screws already on board is desired.

Features and construction details

This screw belongs to the category of self-tapping screws: the geometry is designed to facilitate screwing into the support material, making it practical in many installation and restoration operations. The use of the’AISI 316 makes it a frequent choice in contexts where a quality stainless steel screw is preferred for marine and technical applications.

Product identification

• Manufacturer / supplier: Osculati S.r.l.
• Supplier product code: a4-7982-02.9×019
• Family / reference: UNI 6955 / DIN 7982

Material

• AISI 316 stainless steel: indicated for technical and nautical uses where stainless steel screws suitable for the onboard environment are sought.

, indicated for use as hardware in technical contexts where stainless steel material is preferred. The choice of material is an important element for the consistency of the assembly (screws, washers, accessories, and supports) and to reduce typical issues of mixed assemblies.

• Type: self-tapping screw (Auto TS)
• Size: 2,9×19

Note: for a correct choice it is always advisable to check the screw size and compatibility with the support and the element to be fixed, especially in case of replacement of existing screws.

Typical applications in nautical and plant engineering

A self-tapping screw in AISI 316 is commonly selected for assembly, fastening accessories and maintenance on components where direct tightening is useful. The presence of the reference UNI 6955 / DIN 7982 helps to orient when a type already adopted previously must be respected.

Examples of use (to be evaluated based on the support)

• Fastening small parts and accessories on panels or finishing elements.
• Restoration and replacement interventions of existing screws with the same type.
• Assemblies where a self-tapping screw is preferred to simplify operations.

The final choice always depends on the material of the support, the available thickness, and the installation conditions. In case of doubt, it is advisable to perform a test on a non-critical area or consult the instructions of the accessory manufacturer to be fixed.

Usage and operational notes

To achieve a correct fastening and reduce the risk of damaging the support or screw, it is advisable to adopt some good installation practices. The following indications are generic and should be adapted to the specific case.

Assembly tips

• Preliminary check: check that the size 2,9×19 be compatible with the hole, thickness, and component to be fixed.
• Alignment: keep the screw aligned during screwing to promote regular insertion.
• Proper tool: use an insert/screwdriver suitable for the screw to avoid slipping and marks on the head.
• Controlled tightening: avoid excessive tightening, especially on more delicate materials or on components that could deform.

Notes for replacements and restorations

When replacing an existing screw, in addition to the size it is useful to check:

• the type (self-tapping) and any regulatory reference already used;
• the condition of the support (hole, seat, any wear);
• compatibility with the installed accessory or hardware.

If the goal is to maintain consistency with the original screws, the code a4-7982-02.9×019 and the reference UNI 6955 / DIN 7982 are useful elements for a quick comparison.
