This left-hand thread hex nut is manufactured to DIN 934 standards and made from plain steel—steel without any coating or surface treatment. While the material is strong, it offers little natural resistance to corrosion on its own. The nut features metric threads with a left-hand (LH) thread direction, which is typically used on clockwise-rotating components to prevent loosening. Please note: Class |8| nuts are rated per DIN 267-4 and have a lower load capacity than Class 8 nuts rated to ISO 898-2. Mechanical overload can cause the threads on either the nut or bolt to strip.
