49898729-Flat-Washer-M12
Product ID: 49898729 – Flat Washer M12
Description:
This component is a flat washer with metric M12 nominal size, designed for use in waterjet cutting systems. It is a thin, ring-shaped fastener component placed under a nut or bolt head to distribute load, reduce friction, prevent surface damage, and act as a spacer or shim in mechanical assemblies.
Applications:
Used in waterjet cutting machines under M12 bolts, screws, or nuts in frame assemblies, pump mounts, cutting tank supports, or component attachments.
Installed in high-pressure intensifier assemblies, hydraulic cylinder mounting, or cutting head gantry connections.
Suitable for general mechanical fastening applications within both pure water and abrasive waterjet systems.
Features:
M12 nominal size indicates compatibility with 12 millimeter diameter metric bolts or studs.
Constructed from corrosion-resistant material such as stainless steel, zinc-plated steel, or hardened carbon steel for durability in wet operating environments.
Precision-stamped or machined with flat, parallel faces to provide uniform load distribution.
Smooth inner diameter and outer diameter edges to prevent damage to mating components.
Designed to prevent embedding of the nut or bolt head into softer materials under high clamping loads.
Available in standard metric thickness per ISO or DIN specifications.
Maintenance:
During disassembly, inspect the flat washer for signs of deformation, bending, cracking, or corrosion.
Check for indentation or embedding marks that indicate excessive load or soft mating material.
Replace any washer that shows permanent deformation, cracks, or significant corrosion.
Clean washers with a soft cloth and compatible solvent if being reused; remove all debris, rust, or old thread-locking compound.
Do not reuse a washer that has been crushed, split, or severely compressed beyond its elastic limit.
When reassembling, place the flat washer between the bolt head or nut and the bearing surface as specified in the equipment service manual.
Ensure the washer inner diameter fits freely over the bolt threads without binding.
Tighten the fastener assembly to the torque value specified by the equipment manufacturer; the presence of the washer affects torque-tension relationships.
If vibration or loosening is a concern, use a new flat washer combined with appropriate locking hardware.
Store spare washers in a clean, dry container sorted by size to prevent mixing with other fasteners.
