Osculati self-tapping screw in AISI 316 for technical fastenings

The Auto tc 6.3×25 AISI 316 domed Osculati (supplier code a4-7981-06.3×025) is a self-tapping screw designed for assembly and maintenance interventions in the field of hardware and plant engineering, including typical nautical contexts where reliable and easily identifiable components are sought for reordering.

The product belongs to the family of self-tapping screws with cross recess, with clear identification through code and SKU, useful for consistent replacements and orderly management of the bill of materials.

Product features and details

Material: stainless steel AISI 316

Made of AISI 316 stainless steel, this screw is suitable for technical applications where stainless steel material is preferred for components and fastenings. In nautical and plant engineering fields, the choice of AISI 316 is often associated with durability and resistance needs in demanding environments; in any case, the final selection must always be evaluated based on the actual installation context.

Type: self-tapping screw

Being a self-tapping screw, it is designed to create its own thread in the supporting material during screwing, simplifying many assembly operations. The performance depends on the support, thickness, and correct preparation of the hole (if required) according to good installation practices.

Domed head and cross recess

The model is described as pan head and with cross recess, a common combination for fastenings where a practical operation with common tools and a finish consistent with technical components and accessories is desired. To avoid damage to the drive or head, it is advisable to use the correct insert and work with torque appropriate to the material.

Typical applications

This self-tapping screw can be used in many fastening situations where a practical and orderly solution is required, with stainless steel components and certain identification of the replacement.

• Nautical maintenance and refitting: fastenings on accessories, panels, small parts, and onboard components (depending on the supporting material).
• Technical plant engineering: assemblies of brackets, supports, cable ducts, or finishing elements, when the self-tapping screw is an appropriate choice.
• General hardware: assemblies and repairs where a stainless steel screw with a cross drive is preferred.

Usage and installation notes

Support verification and preparation

Before installation, check:

• the support material and its suitability for self-tapping;
• the thickness and the possible need for pre-drilling (depending on the material and best practices);
• accessibility for the tool and alignment of the fastening.

Tool selection

Use a suitable and well-maintained Phillips insert. A worn insert can increase the risk of slipping and damage the recess, making any future disassembly more difficult.

Torque and tightening

Apply a torque consistent with the material and assembly. Excessive tightening can damage the support or compromise the mechanical hold of the fastening. In case of doubt, proceed with progressive tightening and check the stability of the component.

Compatibility and replacement

For replacements, always compare measurement, head type and code. If the installation requires specific seats or finishes, verify that the head geometry is consistent with the existing housing.

Purchase advice: if you are standardizing onboard or plant hardware, note the code a4-7981-06.3×025 to maintain uniformity in reorder and scheduled maintenance.
