Flat Washer Iran

galvanized flat washer

Galvanized steel flat washers are widely used fastening components designed to distribute clamping forces evenly, protect contact surfaces, and improve the reliability of bolted joints in industrial and construction applications. Manufactured from low or medium carbon steel and protected with electro galvanized or hot dip galvanized coatings, these washers provide enhanced resistance to corrosion, atmospheric moisture, and oxidation while maintaining excellent mechanical performance. Produced in accordance with international standards such as DIN 125, ISO 7089, ISO 7090, and ASTM F844, galvanized flat washers are available in metric and imperial sizes to match a broad range of bolts, nuts, and threaded rods. Their precisely machined inner and outer diameters ensure accurate load distribution, reduce localized bearing stress, and help prevent damage to painted, coated, or machined surfaces during tightening.

Galvanized steel flat washers are extensively used in structural steel, machinery, HVAC installations, piping systems, electrical equipment, cable tray supports, agricultural machinery, and general engineering projects where durable and economical fastening solutions are required. By increasing the bearing surface beneath the bolt head or nut, they improve joint stability,

stainless steel flat washer

Stainless steel flat washers are essential fastening components designed to distribute clamping forces evenly, increase the bearing surface, and protect mating materials from damage during bolt tightening. They are commonly manufactured from A2 (Type 304) and A4 (Type 316) stainless steel, offering outstanding resistance to corrosion, oxidation, moisture, and a wide range of chemicals. Produced in accordance with international standards such as DIN 125, ISO 7089, ISO 7090, and ASTM F844, these washers are available in both metric and imperial sizes for use with hex bolts, socket head cap screws, stud bolts, threaded rods, and stainless steel nuts. Their precision dimensions and smooth surface finish ensure uniform load distribution, minimize localized stress, and improve the overall reliability of bolted joints.

Stainless steel flat washers are extensively used in food processing, pharmaceutical manufacturing, marine engineering, oil and gas facilities, petrochemical plants, water treatment systems, medical equipment, stainless steel structures, and industrial machinery where corrosion resistance is essential. By preventing surface indentation and maintaining consistent preload, they improve joint stability and reduce the risk of fastener loosening under vibration and thermal

Galvanized carbon steel flat washer

Flat washers are used in bolted connections and behind nuts. The flat washer is used as a support to prevent nut damage in the connection on the work piece and as a seat to increase the connection tension. The dry flat washer, which is used in dry bolt and nut connections, has a tensile strength of 800 N/mm2 and has heat hardening treatment. Dry flat washers are manufactured according to DIN125 standard and have a moderate percentage of carbon in the alloy structure.

M10 carbon steel flat washer

Flat washer is actually made of high grades of steel. Dry steel flat washers are used to connect dry Allen screws, dry hex screws, and dry metric screws. Dry flat washers in M10 mm size are widely used in industries and are manufactured according to the DIN125 metric standard in the standard machine of Germany. Dry flat washers are produced in sizes M5 to M30 and are placed between the nut and the work piece.
