AmTech manufactures these Gearbox Output Flange Hex Lock pinion nuts for a TIER 1 Automotive Manufacturer. These pinion nuts feature a double washer, which provide superior gear shaft protection from environmental corrosion elements.
The main body is cast out of steel and then precision screw machined to create an accurate fit onto the shaft with minimal play. The inside surface finish is then ground to final diameter. The first and second washer are then press fit onto the Flanged Hex nut. The item is then zinc plated and ready to be shipped.
