What Buyers Should Know Before Sourcing DIN 6797 Serrated Lock Washers

DIN 6797 serrated lock washers are selected for surface bite and compact locking support. External serrated and internal serrated styles are used in different assemblies, so buyers sourcing them with industrial bolts should confirm washer style, screw size, mating surface, coating, and whether surface marking is acceptable.

For export purchasing, carton strength, moisture protection, label clarity, and document accuracy are important. Serrations can be damaged by rough packing or excessive coating. These washers are practical for many light-duty assemblies, but severe vibration or safety-critical joints may require another approved locking system.

Common Purchasing Descriptions

For consolidated export purchasing, buyers can review related fastener products and request washers, bolts, nuts, and coated parts in one quotation package.

Detailed Specifications Table

Material and Grade Explanation

DIN 6797 serrated lock washers are commonly made from spring steel where serration resilience and economical locking support are needed. Stainless steel options can be supplied for corrosion-sensitive assemblies, but buyers should confirm the grade and expected locking behavior. When washers are shipped with standard fasteners, material compatibility with screws, bolts, nuts, and mating surfaces should be reviewed.

For assemblies where serrations must bite through coating or keep contact under light vibration, material and finish selection should be handled carefully. A washer that is correct by size can still perform poorly if serrations are flattened, over-coated, or damaged during transport.

Surface Finish Selection Guide

Surface finish should be selected by corrosion exposure, mating surface, and storage route. Zinc plated serrated washers are common for general industrial use. Black or phosphate finishes may be used for machinery assemblies. Stainless steel is preferred where corrosion resistance is more important than a plated finish.

For projects where bolts, nuts, and washers need consistent corrosion protection, XZ Fastener can coordinate DIN 6797 supply with related coated fasteners.

Manufacturing and Quality Control

Export supply of DIN 6797 washers requires stable stamping, forming, heat treatment when required, surface finishing, sorting, inspection, and protective packing. Serration form is a key control point. If serrations are shallow, uneven, over-coated, or damaged, the washer may not engage the surface as intended.

1. Confirm DIN 6797 type, size list, material, finish, quantity, and destination.
2. Check material thickness and spring performance requirement before production.
3. Control inside diameter, outside diameter, serration profile, serration height, burrs, and washer shape.
4. Inspect coating appearance and serration condition after finishing.
5. Pack by size, serration type, finish, and lot with export labels and moisture protection.

For special serration forms, OEM kits, or non-standard washer dimensions, buyers can use XZ Fastener’s custom fasteners support before confirming production.

How to Get a Faster Quotation

A clear export RFQ helps confirm tooling, price, lead time, packing cost, and shipment details quickly. For DIN 6797 serrated lock washers, the most important details are serration type, nominal size, material, finish, quantity, destination, packaging method, and inspection requirement.

• Send washer type: external serrated or internal serrated style where applicable.
• Provide nominal sizes and quantity per size.
• Confirm material, stainless grade if needed, and surface finish.
• List carton weight, pallet type, label content, barcode requirement, and destination.
• Specify inspection reports, serration checks, coating checks, and any third-party inspection need.

For direct export support, buyers can contact XZ Fastener with the size list and shipment requirement.
