Washer 10 aisi 316 – code: a4-125-10 – Osculati

Standard flat washer in AISI 316 stainless steel (size 10) – Osculati

The standard flat washer Osculati in AISI 316 stainless steel, in size 10, is a small hardware component designed for use in assemblies and fastenings where it is useful to place a support between screw/nut and the contact surface. This washer, identified by the supplier product code a4-125-10, belongs to the family of standard flat washers with references UNI 6592 and DIN 125.

In the technical field (plant engineering, maintenance, hardware, and typical nautical applications), the washer is commonly used to help achieve a more orderly distribution of tightening and to help protect the material being worked on, reducing direct contact between the fastening element and the surface.

Product features and details

Material: AISI 316

Made of AISI 316 stainless steel, the washer is recommended when you want to use stainless steel hardware in contexts where material choice is important for consistency with the rest of the screws and the working environment (for example, in onboard applications and plant engineering).

Type: standard flat washer

It is a standard flat washer, a standard and widespread solution for multiple fastening operations. The typical use is as an element placed between:

• screw head and support surface, or
• nut and support surface.

This configuration helps create a cleaner and more regular contact point compared to the direct contact of the fastening element on the material.

Format 10

The product is indicated as size 10. When choosing, it is always advisable to check the correct match between the washer size and the screws used, as well as the thickness and nature of the material on which the tightening is performed.

Regulatory references: UNI 6592 and DIN 125

The washer is classified within the family of standard flat washers with references UNI 6592 and DIN 125. These references are useful for guiding the choice of the correct type within technical catalogs and bill of materials, especially when working with standardized components.

Product identification

• Supplier: Osculati S.r.l.
• Supplier product code: a4-125-10
• SKU: oscu0000001339

Typical applications

This washer is a versatile component, usable in many situations where screws and nuts are present and it is desired to improve the support of the tightening.

• Technical hardware for general assemblies and fittings.
• Maintenance standard and interventions on components with stainless steel screws.
• Plant engineering (supports, brackets, and fastenings where an interposed support is useful).
• Boating: typical edge applications where stainless steel fastening elements are used.

The flat washer is often chosen when it is desired to prevent the screw head or nut from working directly on the surface, especially on materials that can be easily marked or deformed.

Usage and selection notes

Verification of size and screws

Before installation, verify that the size 10 both the one suitable for the screw or stud used and that the washer rests correctly on the surface. In case of replacement, it can be useful to compare the existing washer or refer to the technical specification of the component.

Placement

In a standard assembly, the washer is placed between the screw head (or nut) and the surface. It is good practice to ensure that:

• the support surface is clean and free of burrs or obvious irregularities;
• the washer is correctly centered relative to the hole;
• the tightening is done progressively and controlled, according to the application requirements.

Note on standards and replacements

The references UNI 6592 and DIN 125 help identify the washer family. In case of replacement or procurement for maintenance, always report the Osculati code a4-125-10 and verify the size match with the screws in use.

Usage context (nautical and plant engineering)

In edge applications and plant engineering, the choice of stainless steel small parts is often linked to the need to maintain material uniformity and good durability over time. For this reason, when working on existing assemblies, it is advisable to maintain consistency between washers, screws, and nuts already installed, avoiding unnecessary mixes of materials and finishes.
