Flat washer in AISI 316 stainless steel (size 8) – Osculati a4-125-08

The standard flat washer in AISI 316 stainless steel is an essential component to complete fastenings and assemblies in an orderly and correct manner in the field of hardware and plant engineering, including typical contexts of the nautics. This item, supplied by Osculati S.r.l. with product code a4-125-08, is designed to be placed between the screw/nut and the support surface, helping to distribute the tightening and improve the quality of the fastening point.

Features and details

Type: standard flat washer

It is a flat washer (also called “normal washer”), used as a support element in mechanical connections. It is a common solution when a more regular contact is desired between the tightening element (screw or nut) and the material being worked on, especially in the presence of painted, treated, or otherwise to-be-preserved surfaces.

Material: stainless steel AISI 316

The declared material is AISI 316, a frequent choice in applications where stainless steel suitable for exposed contexts and technical uses, including nautical ones, is preferred. During selection, stainless steel is often adopted for consistency with stainless steel bolts and components, thus maintaining fastening uniformity and reducing issues related to heterogeneous materials.

Dimensional references: UNI 6592 and DIN 125

The washer belongs to the washer family according to references UNI 6592 and DIN 125. These references are useful for guidance in selection and comparison with equivalent components, especially when working on maintenance, replacements, or restorations where it is important to maintain geometry consistent with existing bolting.

Recommended applications

This washer is suitable for a wide range of technical uses, where a flat washer is required to complete a fastening in a clean and functional way. In particular, it is useful when:

• you want to interposing a support between nut/bolt and surface, for a tidier tightening;
• performing maintenance interventions on systems and accessories, replacing worn or missing components;
• you are working on hardware assemblies and components, including fittings and restorations in the nautical field;
• you want protecting the finish of the tightening point (for example on treated surfaces), reducing direct contact between the fastening element and the material.

Typical contexts (nautical and onboard systems)

In the nautical sector and onboard systems, the flat washer is a recurring element: it is used in multiple fastening points of accessories, brackets, supports, and system components. The choice of the’AISI 316 stainless steel is often consistent with the need to use materials suitable for exposed environments and with the necessity to maintain uniformity with stainless steel bolts.

Usage and operational notes

Size selection

The size indicated for this item is 8. During selection, it is good practice to verify compatibility with the bolts and with the hole/fitting provided in your assembly, to ensure correct installation without unwanted play.

Matching with screws and nuts

For consistent fastening, it is recommended to pair the washer with screws and nuts compatible in size and use. In case of replacement, it can be useful to compare the existing washer with the family reference (DIN 125 / UNI 6592) to maintain similar geometries and dimensions.

Installation

The washer should be placed between the screw head (or nut) and the support surface. Before tightening, ensure that the surfaces are clean and that the washer rests correctly, without tilting or interference with edges, slots, or irregularities of the support.
