Auto ts 4.2×45 aisi 316 domed – code: a4-7981-04.2×045 – Osculati

Auto TS self-tapping screw Osculati in AISI 316 stainless steel

The Auto TS Osculati is a self-tapping screw designed for technical fastenings and maintenance interventions in the nautical field and onboard systems. This version is made of AISI 316 stainless steel and is distinguished by the rounded head, a practical solution when a neat finish and a good bearing surface of the head on the material are desired.

Features and construction details

Material: stainless steel AISI 316

The screw is made of AISI 316, a stainless steel alloy commonly used in nautical and marine contexts due to its general characteristics of resistance and durability. It is a typical choice for small parts and fastenings exposed to demanding environments, where quality stainless steel components are preferred.

Type: self-tapping screw

Being a self-tapping screw, is suitable for applications where the screw creates its own thread in the supporting material. This approach can be useful in many assembly and maintenance operations, especially when working on panels, coverings, or components that require quick and neat fastening.

Rounded head

The rounded head offers a visually clean finish and a wide contact surface compared to other head geometries. It is often chosen when:

• a visible but discreet and refined head is desired;
• the tightening load needs to be distributed over a larger area of the material;
• working on elements where a flush head is not necessary or not planned.

Product identification and codes

To simplify warehouse management and procurement, this screw is tracked with clear codes:

• Manufacturer/Supplier: Osculati S.r.l.
• Supplier code: a4-7981-04.2×045
• SKU: oscu0000001493

In professional contexts (shipyards, scheduled maintenance, refitting), alignment between supplier code and SKU helps reduce reordering errors and maintain consistency in bill of materials.

Typical applications in nautical and onboard systems

The Auto TS self-tapping screw in AISI 316 is suitable for many general fastening applications where stainless steel small parts are used. In particular, it can be used in activities such as:

• Assembly and fastening of panels and internal/external coverings (depending on the material and hole preparation);
• Installation of accessories and hardware components on suitable surfaces;
• Routine maintenance and replacement of existing screws in onboard systems and fittings;
• Fastening on compatible supports with self-tapping screws, always considering the correct preparation and any pre-drilling.

For specific applications (special materials, high loads, areas subject to vibrations or expansions), it is good practice to define the fastening solution based on the project and the manufacturer's instructions for the element to be installed.

Usage and installation notes

Support verification and preparation

Before installation, it is advisable to evaluate:

• the support material and its suitability for the use of self-tapping screws;
• the need for a pilot hole (depending on the material and processing);
• the presence of thicknesses, spacers or washers, if required by the application;
• the alignment and correct position of the component to be fastened, to avoid stresses or deformations.

Tightening and finishing

During tightening, it is good practice to proceed progressively and controlled, avoiding forcing that could damage the support or compromise the finish. In case of assembly on panels or aesthetic surfaces, correct centering and an adequate tightening torque help achieve a clean result.

Compatibility and replacement

If the screw is used as a replacement, verify that the new hardware is consistent with the removed screw (head type, drive, length, and nominal diameter) and with the mounting seat. For orderly management, refer to the code a4-7981-04.2×045 reported in the datasheet.
