For export orders, buyers usually care about dimensional accuracy, finish consistency, rust protection, carton strength, pallet labeling, and inspection documents. XZ Fastener can supply DIN 9021 washers according to order requirement in carbon steel, stainless steel, or specified materials. These washers are commonly used for sheet metal, slotted holes, painted plates, equipment bases, brackets, and general industrial assemblies where load distribution matters.<\/p>\n        <div class=\"xz-actions\">\n          <a class=\"xz-btn\" href=\"https:\/\/xzfastener.com\/home\/contact-us\/\">Request a Quote<\/a>\n          <a class=\"xz-btn secondary\" href=\"https:\/\/xzfastener.com\/home\/products\/\">View Fastener Products<\/a>\n        <\/div>\n      <\/div>\n      <div>\n        <img fetchpriority=\"high\" class=\"xz-product-img\" alt=\"DIN 9021 large flat washers exporter product illustration\" src='data:image\/svg+xml,%3Csvg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"1200\" height=\"760\" viewBox=\"0 0 1200 760\"%3E%3Crect width=\"1200\" height=\"760\" fill=\"%23eef4fa\"\/%3E%3Crect x=\"84\" y=\"82\" width=\"1032\" height=\"596\" rx=\"28\" fill=\"%23ffffff\" stroke=\"%23b8c9d9\" stroke-width=\"4\"\/%3E%3Cg transform=\"translate(160 135)\"%3E%3Cellipse cx=\"410\" cy=\"292\" rx=\"335\" ry=\"155\" fill=\"%230b2f57\"\/%3E%3Cellipse cx=\"410\" cy=\"258\" rx=\"335\" ry=\"155\" fill=\"%23123f6d\"\/%3E%3Cellipse cx=\"410\" cy=\"258\" rx=\"118\" ry=\"54\" fill=\"%23ffffff\"\/%3E%3Cellipse cx=\"410\" cy=\"258\" rx=\"72\" ry=\"31\" fill=\"%23eef4fa\" stroke=\"%23b8c9d9\" stroke-width=\"7\"\/%3E%3Cpath d=\"M75 258 L75 292 C75 378 225 447 410 447 C595 447 745 378 745 292 L745 258 C745 344 595 413 410 413 C225 413 75 344 75 258 Z\" fill=\"%23092745\" opacity=\"0.35\"\/%3E%3Crect x=\"790\" y=\"138\" width=\"170\" height=\"42\" rx=\"8\" fill=\"%238894a0\"\/%3E%3Crect x=\"790\" y=\"215\" width=\"170\" height=\"42\" rx=\"8\" fill=\"%238894a0\"\/%3E%3Crect x=\"790\" y=\"292\" width=\"170\" height=\"42\" rx=\"8\" fill=\"%238894a0\"\/%3E%3Cg fill=\"%23d7e1eb\"%3E%3Crect x=\"812\" y=\"146\" width=\"12\" height=\"26\"\/%3E%3Crect x=\"842\" y=\"146\" width=\"12\" height=\"26\"\/%3E%3Crect x=\"872\" y=\"146\" width=\"12\" height=\"26\"\/%3E%3Crect x=\"902\" y=\"146\" width=\"12\" height=\"26\"\/%3E%3Crect x=\"812\" y=\"223\" width=\"12\" height=\"26\"\/%3E%3Crect x=\"842\" y=\"223\" width=\"12\" height=\"26\"\/%3E%3Crect x=\"872\" y=\"223\" width=\"12\" height=\"26\"\/%3E%3Crect x=\"902\" y=\"223\" width=\"12\" height=\"26\"\/%3E%3C\/g%3E%3Cpath d=\"M120 548 H940\" stroke=\"%23b8c9d9\" stroke-width=\"32\" stroke-linecap=\"round\"\/%3E%3Cpath d=\"M150 548 H450\" stroke=\"%230b2f57\" stroke-width=\"11\" stroke-linecap=\"round\"\/%3E%3C\/g%3E%3Ctext x=\"600\" y=\"705\" text-anchor=\"middle\" font-family=\"Arial, Helvetica, sans-serif\" font-size=\"34\" font-weight=\"700\" fill=\"%230b2f57\"%3EDIN 9021 Large Flat Washers%3C\/text%3E%3C\/svg%3E' \/>\n      <\/div>\n    <\/div>\n  <\/section>\n\n  <section>\n    <div class=\"xz-wrap\">\n      <h2>Quick Specs<\/h2>\n      <div class=\"xz-card-grid\">\n        <div class=\"xz-card\"><strong>Standard<\/strong>DIN 9021 large flat washer dimensions or buyer drawing.<\/div>\n        <div class=\"xz-card\"><strong>Strength<\/strong>Wide bearing surface for improved load distribution.<\/div>\n        <div class=\"xz-card\"><strong>Material<\/strong>Carbon steel, stainless steel, or specified steel upon request.<\/div>\n        <div class=\"xz-card\"><strong>Finish<\/strong>Plain, black, zinc plated, hot dip galvanized, or custom coating.<\/div>\n        <div class=\"xz-card\"><strong>Application<\/strong>Sheet metal, slotted holes, steelwork, equipment bases, and general assemblies.<\/div>\n      <\/div>\n    <\/div>\n  <\/section>\n\n  <section>\n    <div class=\"xz-wrap\">\n      <h2>What Buyers Should Know Before Sourcing DIN 9021 Large Flat Washers<\/h2>\n      <p>DIN 9021 washers have a larger outside diameter than many standard flat washers. That wider face helps spread clamp load and reduce local surface pressure. When buyers source them with <a href=\"https:\/\/xzfastener.com\/fastener-type\/bolts\/\">industrial bolts<\/a>, the washer inside diameter, outside diameter, thickness, and coating build-up should be checked against the actual assembly.<\/p>\n      <p>For export purchasing, packing is just as important as the washer itself. Mixed sizes, weak cartons, unclear labels, rust marks, or missing documents can delay receiving inspection. Confirming size labels, pallet format, moisture protection, inspection reports, and delivery terms before production makes the shipment easier to handle after arrival.<\/p>\n      <div class=\"xz-note\">If the project references multiple DIN or ISO clauses, buyers can review the <a href=\"https:\/\/xzfastener.com\/din-iso-fastener-standards-complete-overview-for-industrial-buyers\/\">DIN and ISO fastener standards guide<\/a> before finalizing the washer specification.<\/div>\n    <\/div>\n  <\/section>\n\n  <section>\n    <div class=\"xz-wrap\">\n      <h2>Common Purchasing Descriptions<\/h2>\n      <table>\n        <thead>\n          <tr>\n            <th>Export RFQ Wording<\/th>\n            <th>What Should Be Confirmed<\/th>\n          <\/tr>\n        <\/thead>\n        <tbody>\n          <tr>\n            <td>DIN 9021 large flat washers exporter<\/td>\n            <td>Size list, material, finish, destination, packing method, inspection documents, and shipment terms.<\/td>\n          <\/tr>\n          <tr>\n            <td>Large OD flat washers for export<\/td>\n            <td>Confirm DIN 9021 dimensions, washer thickness, hole clearance, and outside diameter.<\/td>\n          <\/tr>\n          <tr>\n            <td>Washers for slotted holes or sheet metal<\/td>\n            <td>Check bearing area, burr control, plating quality, and surface contact requirement.<\/td>\n          <\/tr>\n          <tr>\n            <td>Mixed fastener shipment<\/td>\n            <td>May include DIN 933 full thread hex bolts, Grade 8.8 carbon steel hex bolts, metric hex head bolts, zinc plated DIN 933 bolts, black oxide DIN 933 bolts, and hot dip galvanized DIN 933 bolts.<\/td>\n          <\/tr>\n        <\/tbody>\n      <\/table>\n      <p>For consolidated international orders, buyers can review related <a href=\"https:\/\/xzfastener.com\/home\/products\/\">fastener products<\/a> and request washers, bolts, nuts, and coated parts in one quotation package.<\/p>\n    <\/div>\n  <\/section>\n\n  <section>\n    <div class=\"xz-wrap\">\n      <h2>Detailed Specifications Table<\/h2>\n      <table>\n        <thead>\n          <tr>\n            <th>Item<\/th>\n            <th>Typical Requirement<\/th>\n            <th>Buyer Checkpoint<\/th>\n          <\/tr>\n        <\/thead>\n        <tbody>\n          <tr>\n            <td>Product Type<\/td>\n            <td>DIN 9021 large flat washer<\/td>\n            <td>Confirm DIN standard or provide an approved drawing for special dimensions.<\/td>\n          <\/tr>\n          <tr>\n            <td>Nominal Size<\/td>\n            <td>Metric sizes according to order requirement<\/td>\n            <td>Match washer inside diameter with bolt size and coating build-up.<\/td>\n          <\/tr>\n          <tr>\n            <td>Outside Diameter<\/td>\n            <td>Large OD design per DIN 9021<\/td>\n            <td>Verify required coverage for slotted or oversized holes.<\/td>\n          <\/tr>\n          <tr>\n            <td>Material<\/td>\n            <td>Carbon steel, stainless steel, or specified steel<\/td>\n            <td>State material grade if certificate or corrosion resistance is required.<\/td>\n          <\/tr>\n          <tr>\n            <td>Finish<\/td>\n            <td>Plain, black, zinc plated, hot dip galvanized, or requested coating<\/td>\n            <td>Confirm corrosion exposure, appearance, and coating thickness.<\/td>\n          <\/tr>\n          <tr>\n            <td>Inspection<\/td>\n            <td>Dimension, burr, flatness, visual, and coating checks when required<\/td>\n            <td>Agree sampling plan and report format before production.<\/td>\n          <\/tr>\n          <tr>\n            <td>Export Packing<\/td>\n            <td>Bags, cartons, pallets, labels, or buyer-specific packing<\/td>\n            <td>Separate by size, finish, and lot for receiving and storage control.<\/td>\n          <\/tr>\n        <\/tbody>\n      <\/table>\n    <\/div>\n  <\/section>\n\n  <section>\n    <div class=\"xz-wrap\">\n      <h2>Material and Grade Explanation<\/h2>\n      <p>DIN 9021 washers are often supplied in carbon steel for general industrial applications.
