Auto tc 6.3×32 aisi 316 domed – code: a4-7981-06.3×032 – Osculati

Osculati self-tapping screw in AISI 316 for fastenings in nautical contexts

The Auto tc 6.3×32 AISI 316 Osculati (supplier code a4-7981-06.3×032) is a screw self-tapping designed for fastening and maintenance interventions where hardware is required in AISI 316 stainless steel. It is a typical solution for onboard systems and marine hardware, useful when working on components, accessories, and panels that require direct screwing without pre-threading.

The product is clearly identified by code and supplier reference Osculati S.r.l., an important aspect for reorders, replacements, and managing the bill of materials in the workshop or onboard.

Features and construction details

This screw belongs to the family of self-tapping screws with a cross recess, commonly used in technical applications where quick and repeatable assemblies with common tools are needed. The manufacturer's description includes the references UNI 6954 / DIN 7981, useful as a family/standard indication for those who need to maintain consistency with already installed small parts.

Material: stainless steel AISI 316

The’AISI 316 is a recurring choice in the nautical and onboard systems field when a stainless steel small part suitable for environments exposed to humidity and aggressive atmospheres is desired. During maintenance, using an AISI 316 screw helps maintain material uniformity with other stainless steel components present on the boat or system.

Type: self-tapping screw

The function self-tapping allows the screw to create its own thread seat in the supporting material, simplifying many assembly and replacement operations. It is a practical solution when working on elements where a nut or pre-existing thread is not planned.

Head and recess

• Head: rounded (as per product title).
• Drive: cross-shaped, for screwing with common tools.

The combination of rounded head and cross recess is typical of small parts intended for neat and easily inspectable assemblies, especially when periodic maintenance interventions are performed.

Size and identification

• Size: 6,3×32.
• Supplier code: a4-7981-06.3×032.
• Brand/Supplier: Osculati S.r.l.

For technical purchases and reorders, the presence of the code is a concrete advantage: it reduces the risk of errors when replicating an existing fastening or replacing small parts with equivalent characteristics.

Typical applications (nautical and onboard plant engineering)

This stainless steel self-tapping screw is suitable for general uses of hardware and maintenance in the nautical field, where work is often done on accessories and components that require quick and reliable fastenings over time. In particular, it can be used in many situations where small parts consistent with the use of stainless steel onboard are desired.

Examples of use

• Fastening of small onboard accessories and components.
• Maintenance interventions on panels, covers, and finishes.
• Restoration or replacement of existing screws with traceable code.
• General hardware applications where AISI 316 stainless steel is required.

Note: the choice of the correct screw always depends on the supporting material and the thickness of the element to be fastened. In case of doubt, it is advisable to verify compatibility with the specific application before installation.

Usage and operational notes

To achieve a neat fastening and reduce the risk of material damage, it is good practice to properly prepare the work area and use tools suitable for the cross recess. In the nautical field, it is also often useful to maintain consistency between materials (stainless steel with stainless steel) to simplify maintenance and corrosion management over time.

Practical advice during assembly

• Verify that the size 6.3×32 suitable for the thickness and type of support.
• Use a good condition Phillips screwdriver to avoid slipping on the slot.
• In case of replacement, always compare the removed screw with the code a4-7981-06.3×032 to reduce reordering errors.
• If working on delicate materials or visible finishes, proceed carefully to preserve the surface aesthetics.

Spare parts management and reorder

For workshops, shipyards, and maintenance personnel, traceability is a key aspect. Note the supplier code and keep a small stock of hardware consistent with onboard standards to simplify quick interventions, especially when working on multiple boats or on systems with already defined components.
