304 A2-70 Stainless Steel Hex Toothed Lock Washer Nut M3–M8 Metric Thread K Type
A2-70 grade 304 stainless steel K-type hex nuts with integrated toothed lock washer flange. The serrated flange bites into the workpiece surface when tightened, providing anti-loosening resistance without a separate lock washer. Combines the function of a hex nut and a toothed lock washer in a single component, reducing assembly time and parts count.
