Product Overview
Hex nuts are cold forged and tapped, with across-corners dimensions and nut height to DIN 934 so they pair with DIN 931 and DIN 933 bolts. Class 8 nuts carry proof loads in the 800 MPa band and class 10 covers high strength joints. Every nut passes a go and no-go thread gauge after tapping, so nothing arrives on site that will not start or that strips. Galvanized nuts are tapped with allowance for the coating, which means they still turn onto a matching galvanized bolt by hand.
