The Multiquip 17112 Flat Washer 20MM ZN DIN125A is a genuine OEM component designed for the DAW500SA4 diesel arc welder. Built to DIN125A dimensional standards and zinc-plated for corrosion resistance, this flat washer delivers the consistent clamping and load distribution that precision fastener assemblies demand. As a genuine Multiquip part, 17112 is manufactured to the exact material grade and dimensional tolerances specified for this machine. Confirm your model against the DAW500SA4 fitment before ordering to ensure a direct, specification-correct replacement.
Key Features
- Zinc-Plated Corrosion Protection — DIN125A-compliant zinc coating resists oxidation in demanding jobsite environments, maintaining integrity at fastener contact points.
- Correct Dimensional Spec for 20MM Fasteners — Sized to the 20MM standard, this washer seats flush and distributes load evenly without shimming or adjustment.
- Genuine OEM Quality — Manufactured to Multiquip's original material and tolerance specifications, ensuring the washer performs exactly as the design engineer intended.
- Confirmed Fitment for DAW500SA4 — Sourced directly for the DAW500SA4 diesel arc welder, eliminating guesswork when replacing worn or missing hardware during service.
- Prevents Fastener Loosening and Surface Damage — A properly rated flat washer spreads clamp load across the mating surface, reducing the risk of bolt loosening, surface gouging, or fastener pullthrough over time.
A flat washer serves as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it secures. By spreading clamping force across a wider area, it protects the mating surface from damage, reduces the risk of the fastener working loose under vibration, and helps maintain consistent torque retention. In equipment like the DAW500SA4 diesel arc welder, where structural and mechanical assemblies are subject to engine vibration and thermal cycling, a correctly spec'd washer is essential to keeping fastened joints secure and serviceable over the long term. Using an undersized or incorrect washer can lead to fastener loosening, surface deformation, or premature hardware failure.
