What Buyers Should Know Before Sourcing DIN 6797 Serrated Lock Washers

DIN 6797 serrated lock washers are designed to grip the mating surface through their serrations. External serrated and internal serrated styles are used in different assemblies, so buyers sourcing them with industrial bolts should confirm washer style, screw size, contact surface, and whether surface marking is acceptable.

These washers are practical for many light-duty applications, but they are not a universal solution for severe vibration. Serrations can damage paint, plating, or soft metals, and performance may change if the washer is reused. For safety-critical joints, confirm the locking method with the engineering team before replacing a specified locking nut, adhesive, or wedge-type washer.

Common Purchasing Descriptions

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

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 ordered with standard fasteners, material compatibility with screws, bolts, nuts, and mating surfaces should be reviewed.

For assemblies where the washer must bite through coating or maintain contact, the material and finish should be chosen carefully. A washer that is correct by size can still perform poorly if serrations are flattened, over-coated, or damaged during handling.

Surface Finish Selection Guide

Surface finish should be selected by corrosion exposure, mating surface, and storage condition. 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

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

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

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

Applications

DIN 6797 serrated 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 6797 serrated lock washers, the most important details are serration type, nominal size, material, finish, quantity, 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 bag count, carton weight, pallet type, label content, and barcode requirement.
• Specify inspection reports, serration 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.
