Washer Metric","description":"\u003cp\u003eNord-Lock is the global leader in wedge-locking technology, engineering the world's most reliable locking washers for critical bolted joints. Nord-Lock washers prevent bolt loosening through vibration, dynamic loads, and cyclic stress — not by friction, but through a patented mechanical interlock that actually tightens under load. Used in civil infrastructure, heavy industry, mining, and defence worldwide.\u003c\/p\u003e\u003cp\u003eNord-Lock locking washers are available in Standard, Large O.D., X-Series, and SC Steel Construction variants across Metric and UNC thread sizes, with surface finishes including Delta Protekt coating and 316L or SMO 254 stainless steel for corrosion-critical environments.\u003c\/p\u003e\u003ch2\u003eWhere this product is used\u003c\/h2\u003e\u003cp\u003eNord-Lock locking washers are used in any bolted joint where vibration, dynamic loading, or critical safety requirements demand a positive, non-loosening connection.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHeavy mining and civil equipment where vibration and dynamic loads are constant and bolt loosening is a safety risk\u003c\/li\u003e\n\u003cli\u003eStructural steel, bridge, and infrastructure connections requiring certified, verified bolt security\u003c\/li\u003e\n\u003cli\u003eWind turbines, rail equipment, and marine applications in corrosive or extreme environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eKey specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse;max-width:600px;width:100%;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"background:#1A3A5C;color:#fff;font-weight:bold;padding:8px 12px;text-align:left;border:1px solid #ccc;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"background:#1A3A5C;color:#fff;font-weight:bold;padding:8px 12px;text-align:left;border:1px solid #ccc;\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background:#f5f7fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ccc;font-weight:600;\"\u003eMaterial\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ccc;\"\u003eSMO 254 (Super Duplex SS)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ccc;font-weight:600;\"\u003eSeries\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ccc;\"\u003eLarge O.D.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f7fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ccc;font-weight:600;\"\u003eThread Standard\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ccc;\"\u003eMetric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eSelecting the right option\u003c\/h2\u003e\u003cp\u003eMatch the bolt size (M6–M48 metric, or UNC equivalent) and select the washer series — Standard for typical applications, Large O.D. where load distribution on soft materials is needed, X-Series for ultra-high-strength bolting, and SC for structural steel connections.
