Description

Paulin® Papco® Hex Nut, High Tensile Standard, Series: 670, Measurement System: Metric, M3x0.5 Thread, Carbon Steel, Zinc Plated, Material Grade: 8, 5.5 mm Width Across Flats, ISO Coarse Thread

Metric fasteners, similar to inch fasteners in type and application, are measured in millimeters and often confused with inch types. Ensure to distinguish between inch and metric when replacing fasteners. Metric ones feature distinct markings, grades, and available ISO thread types—Coarse, Fine, and Extra-Fine. Always match replacements exactly. Class 8 zinc-plated fasteners are corrosion-resistant, suited for indoor and industrial use, made from medium carbon steel, and comparable in strength to SAE Grade 5.
