What Buyers Should Know Before Sourcing DIN 6798 Toothed Lock Washers

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

For bulk orders, consistency is critical. Internal tooth and external tooth washers can be confused if labels are unclear, and tooth forms can lose performance if flattened or over-coated. For severe vibration or safety-critical joints, toothed washers should not replace a specified locking method unless the engineering team approves the change.

Common Purchasing Descriptions

For full project or production 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 where tooth resilience and cost control are important. Stainless steel options can be supplied for corrosion-sensitive applications, but buyers should confirm the grade and expected locking behavior. When washers are ordered with standard fasteners, material compatibility with screws, bolts, nuts, and mating surfaces should be reviewed.

For grounding applications, tooth form and surface finish can affect contact quality. A washer that meets the nominal size may still perform poorly if the coating is too heavy or the teeth are damaged during finishing or packing.

Surface Finish Selection Guide

Surface finish should be selected by corrosion exposure, electrical requirements, and storage conditions. 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 bulk programs where bolts, nuts, and washers need consistent corrosion protection, XZ Fastener can coordinate DIN 6798 supply with related coated fasteners.

Manufacturing and Quality Control

Bulk manufacturing of DIN 6798 washers requires stable stamping, forming, heat treatment when required, surface finishing, sorting, inspection, and packing. Tooth form is the most important feature. Flattened, uneven, over-coated, or damaged teeth can change how the washer behaves during assembly.

1. Confirm DIN 6798 type, size list, material, finish, total quantity, and packing rule.
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 clear carton and pallet labels.

For special tooth forms, kit packing, or non-standard washer dimensions, buyers can use XZ Fastener’s custom fasteners support before confirming bulk production.

Aplicaciones

DIN 6798 toothed lock washers can be supplied with other flat washers and standard hardware for bulk replenishment.

How to Get a Faster Quotation

A clear bulk order RFQ helps confirm tooling, price, lead time, packing cost, and production planning quickly. For DIN 6798 toothed lock washers, the key details are tooth type, nominal size, material, finish, quantity, packaging method, label requirement, and inspection documents.

• 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 bag count, carton weight, pallet type, label content, and barcode requirement.
• Specify inspection reports, tooth form checks, coating checks, and any third-party inspection need.

For bulk production planning, buyers can contact XZ Fastener with the size list and delivery schedule.
