Class 8 zinc-plated steel metric hex nut to DIN 934 standard for M8-1.25 thread applications. The zinc plating provides corrosion resistance for use in exposed or semi-exposed automotive locations. Class 8 construction with 116,000 psi tensile strength suits demanding fastening applications — suspension mounts, engine accessories, body hardware, and structural brackets where an M8 thread is specified.

What does Class 8 mean for a metric hex nut?

Class 8 indicates the nut's mechanical strength grade. Class 8 nuts have a proof load stress of 800 MPa and are designed to mate with Class 8.8 bolts. They provide significantly higher clamping force than standard commercial-grade nuts and are appropriate for structural and high-vibration automotive applications.

What is DIN 934?

DIN 934 is an international standard defining the geometry, thread, and dimensional tolerances of standard metric hex nuts. A DIN 934 M8-1.25 nut will be interchangeable with any fastener, tool, or assembly that specifies this thread and standard.

What wrench size do I need for an M8 nut?

An M8 DIN 934 nut has a 13mm across-flats dimension, requiring a 13mm wrench or socket for installation and removal.

Is M8-1.25 a standard or fine thread?

M8-1.25 is the standard (coarse) thread pitch for M8 fasteners. The 1.25 refers to the distance in millimeters between thread peaks. A fine thread M8 would be M8-1.0. Always verify thread pitch before ordering — coarse and fine M8 nuts are not interchangeable.

What pack sizes are available?

Available in packs of 25, 50, 100, and 150 to suit individual repairs or shop stock needs.
