DescriptionNord-Lock Standard Washer – Delta ProtektNord-Lock wedge-locking washers are a two-piece locking washer system engineered to prevent bolt loosening caused by vibration and dynamic loads.Each pair consists of two washers with cam faces on one side and radial teeth on the opposite side. When tightened, the radial teeth grip the mating surfaces while the cam faces create a wedge-locking effect.If the bolt begins to loosen, the cam angle (greater than the thread pitch) forces an increase in clamp load, preventing rotation and maintaining joint integrity.This range features Delta Protekt coating, providing enhanced corrosion resistance for industrial and structural applications.�� How It WorksRadial teeth grip mating surfacesCam faces lock against each otherCam angle exceeds bolt thread pitchPrevents loosening under vibrationMaintains preload even under dynamic loads�� ApplicationsStructural steel assembliesMining & heavy equipmentTransport & railMarine & offshoreIndustrial machineryMaintenance & repair operations⭐ Features & BenefitsProven wedge-locking technologyPrevents self-looseningReusableMaintains preloadSuitable for high vibration environmentsDelta Protekt corrosion resistant coatingGenuine Nord-Lock performance�� Technical InformationType: 2-piece wedge-locking washerStandard: Nord-Lock NL seriesFinish: Delta ProtektFunction: Vibration resistant lockingInstallation: Installed as a pair (cam faces together)[CLICK HERE FOR PRODUCT BROCHURE] [CLICK HERE FOR USER MANUAL]PartQFindDescriptionProductFinishSizeLenWNHTDDM03NL3DPT NORD-L STD WASH:M3(#5)STANDARD WASHERDELTA PROTEKTM3(#5)x7.0x1.8WNHTDDM035NL3.5DPT NORD-L STD WASH:M3.5(#6)STANDARD WASHERDELTA PROTEKTM3.5(#6)x7.6×1.8WNHTDDM04NL4DPT NORD-L STD WASH:M4(#8)STANDARD WASHERDELTA PROTEKTM4(#8)x7.6×1.8WNHTDDM05NL5DPT NORD-L STD WASH:M5(#10)STANDARD WASHERDELTA PROTEKTM5(#10)x9.0x1.8WNHTDDM06NL6DPT NORD-L STD WASH:M6STANDARD WASHERDELTA PROTEKTM6x10.8×1.8WNHTDDM08NL8DPT NORD-L STD WASH:M8(5/16)STANDARD WASHERDELTA PROTEKTM8(5/16)x13.5×2.5WNHTDDM10NL10DPT NORD-L STD WASH:M10STANDARD WASHERDELTA PROTEKTM10x16.6×2.5WNHTDDM12NL12DPT NORD-L STD WASH:M12STANDARD WASHERDELTA PROTEKTM12x19.5×2.5WNHTDDM16NL16DPT NORD-L STD WASH:M16(5/8)STANDARD WASHERDELTA PROTEKTM16(5/8)x25.4×3.4WNHTDDM20NL20DPT NORD-L STD WASH:M20STANDARD WASHERDELTA PROTEKTM20x30.7×3.4WNHTDDM24NL24DPT NORD-L STD WASH:M24STANDARD WASHERDELTA PROTEKTM24x39.0x3.4WNHTDDM30NL30DPT NORD-L STD WASH:M30(1-1/8)STANDARD WASHERDELTA PROTEKTM30(1-1/8)x47.0x5.8WNHTDDM36NL36DPT NORD-L STD WASH:M36(1-3/8)STANDARD WASHERDELTA PROTEKTM36(1-3/8)x55.0x6.6WNHTDDM42NL42DPT NORD-L STD WASH:M42STANDARD WASHERDELTA PROTEKTM42x63.0x6.6WNHTDDM48NL48DPT NORD-L STD WASH:M48(1-7/8)STANDARD WASHERDELTA PROTEKTM48(1-7/8)x75.0x7.0WNHTDDM56NL56DPT NORD-L STD WASH:M56(2-1/4)STANDARD WASHERDELTA PROTEKTM56(2-1/4)x85.0x7.0WNHTDDM64NL64DPT NORD-L STD WASH:M64(2-1/2)STANDARD WASHERDELTA PROTEKTM64(2-1/2)x95.0x7.0WNHTDDM72NL72DPT NORD-L STD WASH:M72STANDARD WASHERDELTA PROTEKTM72105×9.5
