Quick Specs
What Buyers Should Know Before Sourcing DIN 125 Flat Washers
DIN 125 flat washers are simple parts, but washer selection affects clamp load distribution, surface protection, hole coverage, and final assembly reliability. Buyers should confirm inside diameter, outside diameter, thickness, material, hardness, finish, and whether Form A or a specific washer type is required by the drawing.
A flat washer is not a locking washer. It helps spread the bearing load under the bolt head or nut, but it does not replace a spring washer, lock nut, or controlled preload design. For assembly planning, the washer size matching guide is useful when preparing bolt, nut, and washer lists.
Important Sourcing Checks
- Confirm DIN 125, nominal size, inner diameter, outer diameter, and thickness.
- Specify material, hardness class, and whether the washer is hardened.
- Match washer size with bolt diameter, hole size, nut face, and bearing surface.
- Check coating thickness when washers are used with galvanized bolts or nuts.
- Confirm carton weight, small box packing, palletizing, and label requirements.

Material and Grade Explanation
Carbon steel DIN 125 flat washers are widely used for machinery, steel frames, brackets, and general equipment assembly. Stainless steel A2 and A4 washers are often selected for humid, outdoor, marine-adjacent, or appearance-sensitive applications. Brass washers may be used where conductivity, corrosion behavior, or decorative appearance is part of the requirement.
For high-strength assemblies, washer hardness should match the bolt and nut design. When washers are used with Grade 8.8 carbon steel hex bolts, buyers may request 200 HV or 300 HV washers depending on the joint requirement. The XZ Fastener bolt, nut, and washer matching guide can help confirm size pairing before bulk purchasing.
Assembly Matching Notes
- DIN 125 washers are commonly paired with DIN 933 full thread hex bolts.
- Washer inside diameter must fit the bolt shank without excessive looseness.
- Outside diameter should cover the hole and support the bearing area.
- Hardness should be reviewed when the assembly uses high-strength bolts.
- Finish should be selected together with bolts and nuts, not separately.
Surface Finish Selection Guide
Zinc Plated
Zinc plated flat washers are commonly used with zinc plated DIN 933 bolts for indoor machinery, equipment, and general industrial fastening. White zinc and yellow zinc can be discussed by order.
Black Oxide
Black oxide washers are often selected with black oxide DIN 933 bolts for machinery, fixtures, and appearance-controlled assemblies. Additional oiling may be required for storage protection.
Hot Dip Galvanized
Hot dip galvanized washers are commonly used with hot dip galvanized DIN 933 bolts for outdoor steel structures. Buyers should confirm coating thickness and washer dimensions before order.
For coating comparison across bolts, nuts, and washers, review the fastener coating guide and the surface finish selection guide for fastener assemblies.
Manufacturing and Quality Control
DIN 125 flat washer production requires control of stamping accuracy, inner diameter, outer diameter, thickness, flatness, burr condition, surface appearance, hardness, and coating coverage. For hardened washers, heat treatment and hardness testing are important before surface finishing. For decorative or stainless steel washers, surface scratches and edge quality should also be reviewed.
Quality checks can include material verification, dimensional inspection, hardness testing, flatness review, coating thickness testing, salt spray testing when requested, and final packing inspection. XZ Fastener shares more details about quality control for bolts, nuts, washers, and screws for buyers preparing inspection requirements.

Preguntas frecuentes
What is the main function of DIN 125 flat washers?
DIN 125 flat washers distribute clamp load under the bolt head or nut, protect the mating surface, help cover clearance holes, and support a more stable bolted assembly.
Are DIN 125 flat washers locking washers?
No. DIN 125 flat washers are plain washers and do not provide a locking function by themselves. If loosening resistance is required, the assembly may need spring washers, lock nuts, thread locking, or a controlled preload design.
Which hardness should I choose for high-strength bolt assemblies?
For high-strength bolt assemblies, buyers commonly review 200 HV or 300 HV washer options depending on the joint requirement. The final choice should follow the drawing, bolt grade, nut grade, and tightening method.
Can DIN 125 washers be supplied in zinc plated, black oxide, and hot dip galvanized finishes?
Yes. DIN 125 flat washers can be supplied in zinc plated, yellow zinc, black oxide, hot dip galvanized, plain, Dacromet-type coating, and other finishes upon request.
Can washers be packed together with bolts and nuts?
Yes. DIN 125 flat washers can be quoted together with DIN 933 bolts, DIN 934 nuts, threaded rods, anchors, and other fasteners. Please provide the size ratio and packing method for each set.
What information is needed for a DIN 125 flat washer quotation?
Please provide standard, nominal size, material, hardness, finish, quantity, packaging method, destination, and inspection requirements. For custom washers, send a drawing with inner diameter, outer diameter, thickness, and tolerance.
