S-91146A100 9 mm ID DIN 435 Leveling Washers for I-Beams

Key Features & Benefits at a Glance

• Enhanced Load Distribution: Tapered design effectively spreads pressure, reducing stress concentrations and preventing surface damage in M8 fastener applications.
• Superior Corrosion Resistance: Zinc-plated steel construction provides a durable protective barrier, extending service life in demanding industrial environments.
• Guanteed Dimensional Precision: Manufactured to DIN 435 standards, ensuring perfect fit and consistent performance with M8 screws.
• Exceptional Mechanical Strength: Rockwell B52 hardness offers high resistance to deformation under heavy loads, maintaining fastener integrity.
• Broad Industrial Compatibility: The 9mm ID and 22mm width are engineered for seamless integration into a wide range of metric mechanical assemblies.
• Environmental & Regulatory Compliance: Conforms to RoHS 3 and REACH standards, ensuring safety and meeting international supply chain requirements.
• Reliable Vibration Resistance: The tapered profile helps maintain clamp load, reducing the risk of loosening in high-vibration machinery.

Professional Applications & Engineering Value

This M8 tapered washer is engineered to solve critical challenges in heavy-duty assembly. Its zinc-plated steel material provides essential corrosion protection for outdoor equipment, agricultural machinery, and automotive underbody components. The tapered geometry is specifically designed for applications where a standard flat washer is insufficient, such as aligning mismatched holes or compensating for angled surfaces on structural steelwork. By conforming to the DIN 435 standard, it guarantees dimensional interchangeability and reliable performance in metric bolted connections, preventing joint failure and reducing maintenance downtime. This washer is a fundamental component for engineers seeking to enhance the durability and safety of their industrial designs.

Specification Summary & Compliance

This product features a 9mm Inner Diameter, 22mm Width, and a tapered profile with thicknesses of 4.6mm and 1.5mm. It is manufactured from zinc-plated steel and is engineered to meet the precise dimensional and material specifications of the DIN 435 standard. The washer is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental directives, ensuring it is free of restricted hazardous substances and safe for use in regulated markets.
