Through Hardened Washers High-Strength & Durable Industrial Fasteners

Did you know 23% of industrial equipment failures stem from substandard fasteners? When your machinery faces extreme stress, ordinary washers become ticking time bombs. Through hardened washers deliver 3X greater load distribution than regular alternatives – the difference between smooth operations and catastrophic downtime.

Technical Superiority That Outperforms Competitors

Through hardened washers undergo a specialized heat treatment reaching 1500°F (815°C), achieving Rockwell hardness of HRC 45-50. Compare this to case hardened washers (HRC 32-40) that only surface-harden components. Our proprietary process ensures complete through-thickness hardening – no weak points, no compromises.

Precision Customization for Your Unique Needs

Need washers for aerospace fasteners? Mining equipment? Offshore rigs? Our through hardened flat washers come in 38 standard sizes (1/4" to 4" OD) with custom thickness options down to ±0.0005" tolerance. Tell us your operating conditions – we'll engineer the solution.

Proven Success in Extreme Conditions

When a major wind turbine manufacturer switched to our through hardened washers
, bolt failure rates dropped 67% in Arctic installations. Another client in hydraulic cylinder manufacturing reduced warranty claims by 41% after adopting our zinc-nickel coated variants.

FAQS on through hardened washers

Q: What are through hardened washers?

A: Through hardened washers undergo a heat treatment process to harden the entire material, ensuring uniform strength and durability. They resist deformation under high-pressure or heavy-load applications. These washers are ideal for industrial machinery and automotive uses.

Q: How do case hardened washers differ from through hardened washers?

A: Case hardened washers have a hardened outer layer and a softer core, while through hardened washers are fully hardened. Case hardening provides surface wear resistance, whereas through hardening offers consistent strength throughout. The choice depends on load distribution and application requirements.

Q: What are hardened flat washers used with?

A: Hardened flat washers are typically used with bolts, nuts, or screws to distribute load and prevent surface damage. They are common in construction, automotive, and machinery assembly. Their hardened nature ensures longevity in high-stress environments.

Q: When should I choose through hardened washers over standard washers?

A: Choose through hardened washers for heavy-duty applications involving extreme pressure, vibration, or temperature. Standard washers may deform under such conditions, while through hardened versions maintain structural integrity. Industries like aerospace and manufacturing often rely on them.

Q: Can case hardened washers handle high torque applications?

A: Case hardened washers can handle moderate torque due to their hardened surface layer. However, for extremely high torque, through hardened washers are better suited. The application’s specific stress levels determine the optimal choice.
