For Australian engineering, heavy machinery, mining equipment, and any application where bolted joint loosening creates safety or performance issues, wedge lock washers are the engineered solution. AIMS Industrial supplies Nord-Lock wedge lock washers and equivalent products across the standard sizes and materials.\u003c\/p\u003e\n\n\u003ch3\u003eHow wedge lock washers work\u003c\/h3\u003e\n\u003cp\u003eWedge lock washers come in matched pairs. The faces that contact each other have radial cams (like teeth on a saw blade) at a specific angle. When the bolt is tightened, the cam faces lock together — and the cam angle is steeper than the bolt's thread helix. This means any rotation that would loosen the bolt requires the cam faces to ride over each other (taking the bolt with them in the tightening direction). The geometry mechanically prevents loosening from vibration. To remove the bolt, the cam pair must be deliberately broken loose — applied torque overcomes the cam lock.\u003c\/p\u003e\n\n\u003ch3\u003eWhy wedge lock over spring lock washers\u003c\/h3\u003e\n\u003cp\u003eConventional split-ring spring lock washers provide modest spring force but limited rotation resistance. Under sustained vibration, spring lock washers can fully relax (squashed flat) and provide essentially no continuing locking function. Wedge lock washers don't rely on spring force — they rely on the cam geometry, which doesn't degrade in service. The result is a bolted joint that maintains its initial preload over years of operation, where spring lock washer joints may loosen within months in vibrating service.\u003c\/p\u003e\n\n\u003ch3\u003eWhere wedge lock washers earn their place\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy machinery\u003c\/strong\u003e — earth-moving, mining, agricultural equipment subject to constant vibration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWind turbines and rotating equipment\u003c\/strong\u003e — where bolt loosening creates serious safety risk\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRail and transport\u003c\/strong\u003e — where dynamic loads are high and inspection access is limited\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStructural connections in vibrating environments\u003c\/strong\u003e — bridges, machinery foundations\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCritical safety fixings\u003c\/strong\u003e — anywhere fastener loosening creates injury risk\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolted joints subject to thermal cycling\u003c\/strong\u003e — engines, exhaust systems, process equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eNord-Lock — the established brand\u003c\/h3\u003e\n\u003cp\u003eNord-Lock is the Swedish-engineered brand that pioneered the wedge-lock washer system.

Common sizes range from M3 through M48 in metric, with Nord-Lock and equivalent products covering the full range.

Place the matched pair under the bolt head or nut (the cam faces must contact each other; the smooth backs face the bolt and joint surfaces). Tighten the bolt to the specified torque — the wedge lock action engages automatically as the bolt comes up to torque. The pair must be replaced as a pair if disassembled; don't substitute single washers from different pairs.\u003c\/p\u003e\n\n\u003ch3\u003eCompanion ranges at AIMS\u003c\/h3\u003e\n\u003cp\u003eWedge lock washers sit alongside our broader fastener range — see \u003ca href=\"\/en-nz\/collections\/nord-lock\"\u003eNord-Lock\u003c\/a\u003e brand page, \u003ca href=\"\/en-nz\/collections\/safety-washers\"\u003esafety washers\u003c\/a\u003e, \u003ca href=\"\/en-nz\/collections\/schnorr\"\u003eSchnorr safety washers\u003c\/a\u003e, and \u003ca href=\"\/en-nz\/collections\/spring-lock-washers\"\u003espring lock washers\u003c\/a\u003e for the related products.\u003c\/p\u003e\n\n\u003cp\u003eNeed help speccing wedge lock washers for specific applications or vibration concerns? \u003ca href=\"\/en-nz\/pages\/contact-us\"\u003econtact our team\u003c\/a\u003e — we'll match by bolt size, material, and application requirements.\u003c\/p\u003e","products":[{"product_id":"nord-lock-large-o-d-washer-unc-316l-stainless-steel","title":"Nord-Lock Large O.D.
