What Buyers Should Know Before Sourcing DIN 6798 Toothed Lock Washers

DIN 6798 washers are designed with teeth that engage the mating surface. Depending on the type, teeth may be external, internal, or shaped for countersunk applications. Buyers sourcing them with industrial bolts should confirm the tooth style, washer size, mating surface, and whether surface marking is acceptable.

Toothed lock washers are useful in many light-duty assemblies, but they are not a universal answer for severe vibration. The teeth can damage paint, plating, or soft materials, and they may lose effectiveness after reuse. For safety-critical joints, confirm the locking method with the engineering team before replacing a specified nut, adhesive, wedge washer, or prevailing torque fastener.

Detailed Specifications Table

Material and Grade Explanation

DIN 6798 toothed lock washers are commonly made from spring steel when locking action and tooth resilience are important. Stainless steel options can be supplied for corrosion-sensitive assemblies, though buyers should confirm the exact grade and expected locking performance. When washers are ordered with standard fasteners, material compatibility with the mating bolt, nut, and surface should be checked.

For electrical grounding, the washer must make reliable contact through paint, oxide, or coating where the design allows it. In these cases, finish choice and tooth shape are just as important as nominal size.

Surface Finish Selection Guide

Surface finish should be selected by corrosion exposure, electrical requirements, and assembly conditions. Zinc plated toothed 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 6798 supply with related coated fasteners.

Manufacturing and Quality Control

Factory production of DIN 6798 washers requires stable stamping, forming, heat treatment when required, surface finishing, sorting, and packing. Tooth shape is a key control point. If teeth are too weak, too sharp, uneven, or damaged by coating, assembly performance can change.

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

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

Applications

DIN 6798 toothed lock washers can be supplied with other flat washers and standard hardware for factory or project purchasing.

How to Get a Faster Quotation

A clear RFQ helps the factory confirm tooling, price, lead time, and packing quickly. For DIN 6798 toothed lock washers, the most important details are tooth type, nominal size, material, finish, quantity, 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 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 direct factory support, buyers can contact XZ Fastener with the size list and assembly requirement.
