Metric Washers Available at South Coast Fasteners

Metric Washers Offered at South Coast Fasteners

Structural Washers

Structural washers are heavy-duty washers used in steel-to-steel connections alongside structural bolts and heavy hex nuts. They provide a larger bearing surface, spreading the load in critical joints. These washers are common in bridges, buildings, and infrastructure where strength and compliance with codes are essential.

Flat Washers

Flat washers are the most widely used type, placed under bolt heads or nuts to distribute pressure evenly. They help prevent pull-through and reduce surface wear, making them valuable in both light-duty and heavy-duty projects. Flat washers are common in construction, furniture building, and equipment assembly.

Flat Washers Thru Hardened

Flat washers thru hardened are heat-treated for superior hardness and resistance to deformation. They are paired with high-strength bolts where extra durability is needed. Industrial construction, heavy machinery, and demanding structural applications rely on thru hardened washers to maintain secure fastening under stress.

Flat Washers Stainless

Flat washers stainless are designed for corrosion resistance and durability in harsh environments. They are frequently used in marine, chemical, and outdoor applications where moisture or exposure would compromise other materials. Stainless flat washers keep assemblies strong and stable even when exposed to the elements.

Lockwashers

Lockwashers are made to resist loosening caused by vibration, movement, or shock. By applying tension against the fastener, they help keep bolted joints tight under dynamic conditions. They are widely used in automotive, machinery, and electrical assemblies where vibration is a constant factor.

Lockwashers Stainless

Lockwashers stainless offer the same vibration resistance as standard lockwashers but with the added benefit of corrosion protection. They are used in marine, food processing, and chemical industries where both security and resistance to rust are required. Their durability makes them ideal for harsh or wet conditions.

Brass

Brass washers provide corrosion resistance and electrical conductivity, making them valuable in electrical and plumbing applications. They also have a decorative finish that works well in architectural and design-focused assemblies. Brass washers resist tarnishing and maintain performance in non-ferrous connections.

Metric Washers - Industry Applications

Metric washers are essential in industries that require dependable fastening systems. Construction crews rely on them to secure steel connections, while manufacturing facilities use washers to protect machinery and equipment. In utilities, washers reinforce tower and pole assemblies, and in marine environments, stainless or brass washers provide corrosion resistance where moisture is unavoidable.

Washers not only protect surfaces but also add reliability and stability to fastening systems. By preventing loosening, distributing stress, and extending service life, they keep projects safe, efficient, and compliant with performance standards.

Metric Washers - Material Options

South Coast Fasteners stocks metric washers in the following materials, each designed to serve different environments and applications.

Low Carbon Steel

Low carbon steel washers are a cost-effective solution for general applications. They provide dependable load distribution and surface protection in construction and assembly projects. These washers are widely used where corrosion resistance is not the primary concern but reliable performance is still required.

Alloy Steel

Alloy steel washers offer superior hardness and strength, making them suitable for use with high-strength bolts in demanding environments. They resist wear and deformation under heavy loads, which is why they are often specified in industrial and structural assemblies. Their durability makes them a trusted option in high-stress projects.

Stainless Steel A2 (18-8)

Stainless steel A2 (18-8) washers provide good corrosion resistance for general outdoor, food processing, and mild chemical applications. They are versatile and dependable in environments where exposure to moisture is common. These washers strike a balance between strength and corrosion protection, making them a widely used stainless option.

Stainless Steel A4 (316)

Stainless steel A4 (316) washers are engineered for maximum corrosion resistance in saltwater, marine, and chemical environments. They maintain their integrity even under constant exposure to moisture and harsh elements. For coastal, offshore, and industrial chemical projects, stainless steel A4 (316) washers are the material of choice.

Brass

Brass washers combine corrosion resistance with electrical conductivity and aesthetic appeal. They are frequently used in electrical systems, plumbing assemblies, and decorative applications where non-ferrous materials are preferred. Brass washers are valued for both function and finish.

Metric Washers - Available Finishes

South Coast Fasteners offers metric washers in finishes designed to extend durability, resist corrosion, and improve performance across industries.

Zinc Cr+3

Zinc Cr+3 provides a bright, silver-toned coating with moderate corrosion resistance. It is often used on washers in indoor machinery, light manufacturing, and assemblies where cost-effectiveness and functionality matter most. This finish adds basic protection while keeping the washer profile clean and practical.

Zinc Blue Cr+3

Zinc Blue Cr+3 creates a bright silver-blue appearance with slightly enhanced corrosion resistance compared to standard zinc. It is frequently used in machinery, automotive assemblies, and equipment where both appearance and protection are important. The blue hue also helps distinguish these washers from other finishes in mixed hardware applications.

Yellow Zinc Cr+6

Yellow Zinc Cr+6 delivers a golden finish and stronger corrosion resistance than standard zinc coatings. It is favored in automotive, agricultural, and electrical projects where durability and visual identification are both beneficial. The coating provides dependable protection in moderate outdoor conditions.

Yellow Zinc Cr+6 Bake

Yellow Zinc Cr+6 Bake includes a baked treatment that reduces hydrogen embrittlement risk, making it appropriate for high-strength washers. It is commonly specified in automotive, aerospace, and structural projects where performance under stress is critical. The baked finish extends service life and reliability.

Plain

Plain washers are untreated and offer an economical option for indoor or controlled environments. They are a practical choice for applications where the washers will be painted, plated, or otherwise coated later. Their simplicity and versatility make them suitable for a wide range of assemblies.
