Auto ts 3.5×16 aisi 316 countersunk – code: a4-7982-03.5×016 – Osculati

Osculati Auto TS 3.5×16 self-tapping screw in AISI 316 stainless steel (countersunk)

The Auto TS 3.5×16 by Osculati is a self-tapping screw made of AISI 316 stainless steel, , designed for fastening and maintenance interventions in technical contexts where reliable and easily available small parts are required. The product is identified by the supplier code A4-7982-03.5X016, useful for reorders, replacements, and spare parts warehouse management.

This version is indicated as countersunk and belongs to the family of screws commonly used in nautical and in’onboard systems, , as well as in many general hardware applications. The choice of’AISI 316 is typical when a stainless steel solution is desired for demanding environments and for components exposed to moisture or external agents, in compliance with the manufacturer's indications.

Product features and details

Identification and codes

For correct identification of the spare part, refer to the following data:

• Manufacturer / supplier: Osculati S.r.l.
• Supplier product code: A4-7982-03.5X016
• Type: self-tapping screw (Auto TS)
• Material: stainless steel AISI 316
• Format: 3.5×16

Head shape

The screw is indicated as countersunk: this geometry is commonly chosen when a fastening with limited bulk and a neater appearance flush or semi-flush with the surface is desired, depending on the material and the machining performed. When choosing, it is good practice to verify that the seating area (for example, the countersink of the hole or the housing in the component) is consistent with the intended head.

Standard references (as indicated by the manufacturer)

The product is associated with the references DIN 7982 and UNI 6955 (according to what is reported by the manufacturer). These references help to guide the selection of small parts and to compare equivalent items by family and intended use, especially when managing replacements on existing systems.

Typical applications

The self-tapping screw is a practical solution for direct fastening on suitable materials, when you want to simplify installation and reduce operational steps compared to screws that require preformed threads. In nautical and plant engineering fields, this type is often chosen for assembly, restoration, or replacement of components where it is important to work with standard and easily identifiable small parts.

Areas of use

• Marine and onboard plant engineering: fastenings on paneling, accessories, and hardware components, based on materials and setup requirements.
• Technical maintenance: replacement of existing screws with a definite reference to product code and family.
• General hardware: applications requiring a stainless steel screw with a countersunk head for a cleaner result.

Usage and installation notes

To achieve correct fastening with a self-tapping screw, it is important to consider the support material and the preparation of the fastening point. Below are some general guidelines (not a substitute for manufacturer procedures or best practices in your sector):

Hole preparation and material pairing

• Evaluate the support: the fastening performance depends on the material being screwed into and the condition of the component (thickness, integrity, any treatments).
• Alignment and head seat: with a countersunk head, check that the seat is consistent to avoid uneven support or non-uniform finishes.
• Metal compatibility: when different materials are present, consider best practices to reduce unwanted effects caused by metal pairing and the usage environment.

Assembly and maintenance

• Controlled screwing: apply a torque appropriate to the material and seat, avoiding excessive tightening that could damage the support or the screw.
• Periodic inspection: in applications subject to vibrations or stresses, it is useful to plan inspections and, if necessary, replacement of small parts.
• Consistent replacement: for replacements, use the product code to maintain consistency in screw format and family.
