This hex nut, manufactured to DIN 934 specifications, is made of steel with an electro-galvanized finish, making it ideal for indoor use or applications with very mild environmental exposure. It features a metric left-hand (LH) thread, which is typically used on components that rotate clockwise to prevent loosening during operation. Please note: Class |8| nuts are rated according to DIN 267-4 and have a lower load capacity than Class 8 nuts rated to ISO 898-2. Mechanical overloading can strip the threads on either the nut or the bolt.
