Plain Washers (Flat Washers) — Load Distribution & Surface Protection

Plain Washers/ Flat Washer

Plain washers — also referred to as Flat Washers or DIN 125 washers — are simple yet critical fasteners used to distribute load, protect surfaces, and prevent damage in bolted assemblies. At Horizon Inc., we supply a wide range of Flat Washers in stainless steel, carbon steel, brass, and nylon variants, conforming to metric standards and engineered for durability across applications.

Materials, Finishes & Standards

Material Options

Stainless Steel (A2/304, A4/316): For corrosion resistance in harsh or outdoor environments
Carbon Steel (plain, zinc plated, black oxide): Economical for indoor/controlled use
Brass / Copper: For electrical or non-magnetic applications
Nylon / Plastic: For insulation, vibration damping, and non-metallic uses

Dimensional Standards & Sizing

We manufacture Flat Washers in metric sizes (M3 up to M72) following DIN 125 / ISO 7089 standards. Use the standard table of inner diameter (ID), outer diameter (OD), and thickness to match bolt size. (Here insert a table or datasheet link.)

How to Choose the Right Flat Washer

Match the inner diameter to the bolt shank (e.g. M8 bolt → M8 washer)
Choose appropriate outer diameter and thickness per load, surface hardness, and material
Decide material & finish based on the operating environment (corrosion, temperature, electrical)
For sheet metal, consider fender / penny washers (larger OD)
Validate against DIN/ISO tolerances for fits in precision assemblies
