Product Details

These DIN 433 HV washers function as thin, flat components with a central hole, designed to sit between bolt heads/nuts and surfaces, evenly distributing clamping forces to prevent deformation and ensure secure holds in high-stress setups. The HV head mark signifies hardness levels, enabling use with bolts requiring robust support, while surface treatments like black oxide provide a non-reflective, wear-resistant finish, and zinc plating adds a bright, rust-proof layer for varied conditions. Sizes range from M1 to M36, with precise dimensions tailored for compact installations, minimizing space while maximizing efficiency. Duojia’s stamping process ensures edge smoothness and mark clarity, certified by SGS for mechanical reliability. Installation involves placing the washer under the bolt or nut, tightening to the recommended torque to avoid over-compression—clean surfaces beforehand for optimal contact. Regular inspections for wear or corrosion are advised, especially in vibrational environments; replace if deformed to maintain performance. These washers excel with socket-head or cheese-head screws in automotive chassis, machinery frames, and equipment housings. With custom sizing available, minimum orders of 100 pieces, and 14-30 day fast delivery in protective packaging, they are exported worldwide, offering a versatile, high-strength option for stable, pressure-distributed fastening.

Product Parameters

Product Features

DIN 433 HV Washers boast a compact, flat design with HV hardness markings, enabling precise pressure distribution that safeguards bolts and surfaces from excessive stress, outperforming standard washers in high-load scenarios. Made from high-strength carbon steel, with options for black oxide to resist wear or zinc plating for corrosion protection, they maintain integrity in abrasive or humid conditions. Custom sizing from M1 to M36 allows tailored fits for tight spaces, ensuring minimal protrusion while maximizing stability with cheese-head or socket-head screws. Duojia’s engineering supports bespoke dimensions, all tested for hardness and flatness to prevent warping under torque. These washers reduce friction during assembly, facilitating smoother tightening and disassembly without thread damage. Their robust construction handles vibrations effectively, making them suitable for dynamic machinery without loosening. Lightweight and thin, they add negligible weight to assemblies, while eco-friendly production minimizes environmental impact per ISO standards. Versatile surface finishes enhance adaptability, requiring only basic cleaning for upkeep. This suite of attributes provides enhanced load bearing, surface protection, and reliability, positioning them as a superior choice for applications demanding durable, space-efficient fastening with consistent performance.

Product Applications

Custom-Sized DIN 433 HV Washers are crucial for high-strength bolting in machinery, where they distribute pressure under socket-head screws in engine components or frames, preventing deformation in tight clearances. Automotive assemblies utilize them for chassis and suspension bolts, ensuring stable joints amid vibrations for safer vehicle operation. In industrial equipment, they protect surfaces in gear housings or mounts, pairing with medium-strength bolts to maintain integrity under load. These washers suit construction for securing fixtures in confined spaces, reducing stress on materials like metal or composites. Duojia’s fast delivery supports urgent needs in manufacturing lines, with simple placement enhancing workflow efficiency. Their HV hardness excels in high-torque scenarios, requiring periodic checks for wear to sustain performance. Versatile for both indoor precision work and outdoor durability with plated variants, they minimize failures, improving safety in sectors from electronics to heavy machinery. With global availability, they facilitate custom engineering projects, ensuring even pressure distribution and long-term reliability in diverse fastening tasks.
