Specification Brand : FOCMKEAS BulletPoint1 : 【Package & Size】1 piece Flange Coupling Connector; 7mm(0.28 inch) inner Dia 16mm(0.63 inch) external diameter; Net Weight: 30g(1.06 oz). BulletPoint2 : 【Material】The coupling connector is Exquisite iron plating chromium,maded of C45 Carbon Steel (it is better than copper and aluminum alloys), thereby improving the toughness and corrosion resistance of the rigid flange coupling, electroplated process make it sturdiness and insulation, striking shaft more stable and easy for installment and replacement. BulletPoint3 : 【High precision】The shaft coupling is made of high-precision technology, which can realize the tight connection of the 2 shafts, and the model machine is not easy to separate during the operation. BulletPoint4 : 【Low inertia】Shaft coupler is so highly sensitive that can quickly switch the working state, efficient and swift. BulletPoint5 : 【Wide application】Flange coupling is a special coupling that can fix a shaft to a flat surface and can easily install other accessories on the shaft, widely used in model shaft connection, perfect accessories for RC model motors, etc. Color : Silver Department : Unisex Adult ExteriorFinish : Aluminum ExternallyAssignedProductIdentifier : 8719735007582 ExternallyAssignedProductIdentifier1 : 791809896245 ExternallyAssignedProductIdentifier2 : 0791809896245 FinishType : Polished IncludedComponents : No ItemName : FOCMKEAS 7mm(0.28 in) Flange Shaft Coupling, Rigid Coupling Motors Guide Support Coupler, High Hardness Connector Flanged Mount for DIY RC Model Motors Coupler with Set Screws & Wrench ItemPackageDimensions_Height : 0.59 inches ItemPackageDimensions_Length : 2.76 inches ItemPackageDimensions_Width : 1.97 inches ItemPackageQuantity : 1 ItemTypeKeyword : set-screw-couplings Manufacturer : FOCMKEAS Material : Carbon Steel Material1 : Cast Iron Material2 : Stainless Steel Material3 : Plastic MeasurementSystem1 : Metric MeasurementSystem2 : Inch MetalType : Carbon Steel MetalType1 : Aluminum MetalType2 : Carbon Steel MetalType3 : Copper MetalType4 : Iron ModelName : ZVHZQEMMT ModelNumber : 2021031204-Flange Coupling NumberOfItems : 1 NumberOfPieces : 1 PackageLevel : unit PartNumber : 7mm id-16mm od ProductDescription : 1.Wide Range of Applications: rigid couplings can fix the shaft on the plane, and can easily install other accessories on the shaft, widely used in model shaft connection, perfect accessories for RC model.
