Metric Grade A Fender Washer, DIN 9021B, Zinc CR+3

These fender washers feature a larger outer diameter to spread load across wider surfaces, protecting materials from pull-through or distortion. The DIN 9021B standard ensures reliable sizing and fit for consistent performance. They are often chosen for sheet metal work, automotive body panels, and equipment repair where added stability is important. With a zinc CR+3 finish, they also maintain corrosion resistance in everyday conditions.

Metric DIN 125A Flat Washer, 140 HV, Plain

A basic yet dependable choice, the DIN 125A flat washer with 140 HV hardness offers solid support under standard fastening loads. Its plain finish makes it best suited for dry, indoor applications where corrosion resistance is not the primary concern. These washers are commonly used in machinery assembly, manufacturing equipment, and general maintenance. Their simplicity and strength make them a cost-effective option.

Metric DIN 125A Flat Washer, 140 HV, Zinc CR+3

This version of the 140 HV flat washer comes with a zinc CR+3 coating for added protection against moisture and light corrosion. It combines the strength of the 140 HV hardness rating with an extra layer of durability for outdoor or semi-exposed environments. Industries such as construction and automotive often rely on this option for dependable fastening. Its protective finish helps extend service life while keeping surfaces secure.

Metric DIN 125A Flat Washer, 140 HV, Zinc Yellow CR+6

The zinc yellow CR+6 finish on these 140 HV washers provides both corrosion resistance and a distinct color that can aid in assembly identification. This makes them useful in environments where quick visual checks are part of maintenance or safety standards. Applications include electrical equipment, construction, and industrial systems. They combine hardness with finish reliability, delivering performance under everyday working conditions.

Metric DIN 125A Flat Washer, 200 HV, Plain

Offering a stronger hardness rating, the 200 HV plain washer is suited for fastening assemblies that see greater tension and torque. With no coating, it is generally recommended for indoor or low-exposure environments. These are a dependable choice in heavy equipment, mechanical repairs, and industrial projects where added strength is required. Their balance of toughness and affordability makes them a frequent go-to for professionals.

Metric DIN 125A Flat Washer, 200 HV, Zinc CR+3

This 200 HV washer provides higher load-bearing strength with the added benefit of a zinc CR+3 protective coating. It is ideal for fastening assemblies in construction, transportation, and field maintenance where exposure to moisture or wear is common. Its balance of strength and protection makes it a reliable choice for both contractors and engineers. These washers offer durability without compromising performance.

Metric DIN 125A Flat Washer, 200 HV, Zinc Yellow CR+6

Adding zinc yellow CR+6 to a 200 HV washer brings not only extra corrosion resistance but also an easy-to-identify finish. They are frequently used in utility work, electrical installations, and assembly lines where durability and quick visual verification both matter. Their higher hardness ensures they perform well under demanding torque. This combination of finish and strength makes them one of the most versatile options available.

Metric DIN 125A Flat Washer, 300 HV, Plain

For the toughest fastening applications, the 300 HV washer delivers maximum hardness in a simple, uncoated form. It is best suited for high-stress assemblies in controlled environments where coatings are not required. Heavy machinery, structural connections, and critical equipment repairs are examples where this washer excels. Its plain finish keeps costs reasonable while still providing exceptional strength.

Metric DIN 125A Flat Washer, 300 HV, Zinc CR+3

Adding zinc CR+3 protection to a 300 HV washer creates a part that withstands both high stress and corrosive conditions. These washers are used in industries such as energy, infrastructure, and transport where durability is essential. They combine hardness and finish for long-term reliability in harsh working environments. Engineers often specify them when safety and longevity are priorities.

Metric DIN 7349 Thick Flat Washer, Zinc CR+3

Thicker than a standard flat washer, the DIN 7349 style offers added load distribution and strength. This makes it valuable in heavy construction, bridgework, and equipment installation where extra support is needed. The zinc CR+3 finish provides corrosion resistance for outdoor or exposed conditions. These washers are chosen when stability and reinforcement are top concerns.

Metric DIN 433 Small Flat Washer, Zinc CR+3

Designed for smaller fasteners, the DIN 433 washer provides the same benefits of load distribution and surface protection in a compact size. It is frequently used in precision equipment, electronics, and smaller machinery where tight spaces require scaled-down components. The zinc CR+3 coating ensures they resist wear from moisture and light exposure. These small washers may be compact, but they play a critical role in securing assemblies.

Metric Grade C Fender Washer, DIN 9021B, Zinc CR+3

The Grade C fender washer combines a large diameter with a heavier duty grade, making it capable of supporting higher stresses. Its zinc CR+3 finish provides resistance against rust and wear, extending its service life. These washers are relied upon in automotive, construction, and equipment manufacturing. They offer both coverage and strength, protecting surfaces while holding fasteners securely.
