Black Oxide Grade 4.8 M5 M6 Double End Wheel Stud Metal Bolts WITH Heavy DUTY Nut WASHER DIN938 DIN125 DIN934

This product is a precision-engineered fastening kit specifically designed for wheel stud applications and other heavy-duty double-ended fastening needs. The core component is a double end stud bolt manufactured from carbon steel to Grade 4.8 specification, available in M5 and M6 sizes. It features a black oxide finish, which provides a mild level of corrosion resistance, reduces light reflection, and allows for the absorption of lubricating oils. This stud bolt is designed to conform to DIN938, a standard for stud bolts with a double-end configuration. The comprehensive kit includes a heavy-duty hex nut (conforming to DIN934) and a heavy-duty washer (conforming to DIN125), both manufactured to matching quality standards. This creates a complete, ready-to-install fastening assembly ideal for applications requiring a robust, replaceable stud-and-nut system.

The double-end stud design offers engineering benefits: it allows for a component to be pre-located on the studs before nuts are applied, simplifies assembly in tight spaces, and provides a durable threaded post that can outlast threads cut directly into softer materials. The black oxide finish provides a professional, non-reflective appearance and serves as an excellent base for retaining assembly lubricants. The inclusion of a heavy-duty nut and washer ensures the clamping load is properly distributed and that the assembly has the strength to withstand repeated use.
