What Buyers Should Know Before Sourcing DIN 6798 Toothed Lock Washers

DIN 6798 washers use teeth to bite into a mating surface. The correct type depends on where the teeth must act: outside the washer, inside the hole, or under a countersunk screw. Buyers sourcing them with industrial bolts should confirm tooth style, washer size, screw head type, and whether surface marking is acceptable.

For export purchasing, packing and documentation matter as much as the washer itself. Tooth forms can be damaged by rough handling, and mixed internal or external tooth washers can create assembly mistakes. XZ Fastener recommends confirming carton weight, label format, moisture protection, inspection documents, and destination requirements before shipment.

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 6798 toothed lock washers are commonly made from spring steel when tooth resilience and economical locking support are required. Stainless steel options can be supplied for corrosion-sensitive environments, but buyers should confirm the grade and expected locking behavior. When washers are shipped with standard fasteners, material compatibility with screws, bolts, nuts, and the mating surface should be checked.

For grounding applications, the tooth design must create reliable contact through coating, oxide, or paint where the design allows it. In these cases, finish selection and tooth profile are not secondary details; they directly affect assembly performance.

Surface Finish Selection Guide

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

For projects where bolts, nuts, and washers need consistent corrosion protection, XZ Fastener can coordinate DIN 6798 supply with related coated fasteners.

Manufacturing and Quality Control

Export supply of DIN 6798 washers requires stable stamping, forming, heat treatment when required, surface finishing, sorting, and packing. Tooth form is a key control point. If teeth are flattened, uneven, over-coated, or damaged during transport, assembly performance can change.

1. Confirm DIN 6798 type, size list, material, finish, quantity, and destination.
2. Check material thickness and spring performance requirement before production.
3. Control inside diameter, outside diameter, tooth profile, tooth height, burrs, and washer shape.
4. Inspect coating appearance and tooth condition after finishing.
5. Pack by size, tooth type, finish, and lot with export labels and moisture protection.

For special tooth forms, OEM packs, 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 6798 toothed lock washers, the key details are tooth type, nominal size, material, finish, quantity, destination, packaging method, and inspection requirement.

• Send washer type: external tooth, internal tooth, or countersunk 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, tooth form 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.
