Placed between screw/nut and support surface, it helps create a more orderly and regular contact, aiding in distributing the tightening load over a wider area compared to the threaded element alone.

This washer belongs to the family of standard flat washers and is indicated when you want to maintain consistency with stainless steel hardware, for example in maintenance, replacement, or onboard fitting interventions. Product supplied by Osculati S.r.l. and internally identified with SKU oscu0000001654.

Features and details

Material: AISI 316

Made of AISI 316 stainless steel, the washer is suitable for contexts where it is preferred to use stainless steel components for fastening uniformity and greater suitability for use in typical nautical and onboard plant environments. The choice of material is particularly useful when the rest of the bolts or hardware is already stainless steel.

Type: standard flat washer

It is a standard flat washer, a standard and versatile solution for many tightening applications. It is commonly used to:

• create a more uniform support between the fastening element and the surface;
• reduce the risk of marking the surface, especially on more delicate materials;
• improve the order and cleanliness of the assembly, especially in visible installations.

Dimensional and regulatory references

The washer is indicated as size 12 and shows references UNI 6592 and DIN 125, commonly associated with standard flat washers. These references are useful for those who need to maintain continuity with existing components or who follow workshop and maintenance specifications.

Typical applications (nautical and plant engineering)

In nautical and technical fields, a flat washer is often chosen as a “service” component to properly complete a fastening. The washer 12 AISI 316 can be used in many situations, for example:

• Onboard maintenance: replacement of existing small parts, restoration of loose or worn fastenings, interventions on accessories and supports.
• Setups and installations: assembly of brackets, supports, plates and components where it is useful to place a washer between nut/bolt and surface.
• Plant engineering: completion of tightening on support elements, collars, brackets and fastening components in general.
• Fastenings on painted or finished surfaces: when a cleaner and more regular support is desired, reducing the direct contact of the nut or bolt head.

The choice of a normal flat washer is particularly practical when you want to keep the assembly simple and standard, without resorting to unnecessary special solutions.

Usage and selection notes

How to choose the correct washer

The washer is indicated as size 12: when choosing, it is important to check the correspondence with the bolts and the specific application (bolt, nut and clearance hole). In case of doubt, it is advisable to compare the existing washer to be replaced or refer to the specifications of your assembly.

Matching with stainless steel bolts

To maintain consistency and uniformity of fastening, it is generally preferable to match the washer with stainless steel bolts and components, especially in nautical and plant engineering contexts where stainless steel is a recurring choice.

Notes for installation and maintenance

• Check that the bearing surfaces are clean and free of burrs or irregularities that could compromise the support.
• Check that the washer is correctly centered with respect to the bolt or stud before tightening.
• In case of replacement, evaluate the condition of the bolts and the contact surface to restore a neat fastening.
