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.
