Key Features

• Genuine OEM Spring Tension Integrity — manufactured to Bomag's original specification, delivering the correct load rating and spring deflection for secure, vibration-resistant fastening
• Drop-In Hardware Replacement — matches the original washer's dimensions and seating profile exactly, fitting the same bolt positions without modification
• Broad Equipment Coverage — fits an extensive range of Bomag machines including BW-series single drum, tandem, walk-behind, pneumatic tyred, and trench compactor rollers, BF-series pavers, MPH and RS recyclers and stabilizers, BS and BSF recyclers and stabilizers, BC refuse, landfill, and soil compactors, and more
• Fastener Joint Reliability — spring washers prevent bolt loosening under the sustained vibration loads typical of compaction and paving equipment; a worn or missing washer can lead to fastener back-out and assembly failure
• Verified Part Number — sourced and supplied as Bomag part number 08531221, so you order with confidence and receive the correct component every time

A spring washer is a small but essential fastening component placed under a bolt or nut to maintain clamping force in joints that are subject to vibration, thermal cycling, or dynamic loading. By exerting a continuous spring load against the fastener, it resists the loosening that normal machine vibration would otherwise cause over time. On compaction equipment and pavers — machines that generate significant continuous vibration during operation — spring washers are particularly important at structural, drivetrain, and panel attachment points. When a spring washer flattens, corrodes, or is omitted during reassembly, the fastener it supports can back out, leading to loose components, accelerated wear at mating surfaces, and potential assembly failure.
