What does Class 8 mean for a metric hex nut?
The property class designation (Class 8) indicates the mechanical strength of the nut. Class 8 nuts have a proof load stress of 800 MPa and are rated to mate with Class 8.8 bolts. They provide significantly higher clamping force than standard commercial-grade nuts and are suitable for structural and high-stress automotive fastening applications.
What is DIN 934?
DIN 934 is a German/international standard that defines the dimensions, tolerances, and geometry of standard metric hex nuts. A DIN 934 nut has a consistent across-flats dimension (10mm for M6), thread profile, and height — making it interchangeable with any fastener or application that specifies this standard.
Why is this nut plain finish rather than zinc-plated?
Plain (uncoated) steel nuts are used in applications where zinc plating may interfere with paint adhesion, welding, or where the nut is in a protected location. They are also preferred when the mating bolt is already coated, to avoid galvanic incompatibility between different surface finishes.
What wrench size do I use for this nut?
An M6 DIN 934 hex nut has a 10mm across-flats dimension, requiring a 10mm wrench or socket. This is one of the most common metric wrench sizes in automotive repair toolkits.
What pack sizes are available?
Available in packs of 25, 50, 100, and 150 to suit individual repairs or shop supply needs.
