Product Description

PRODUCT PARAMETER

HEX NUT

Hexagon nuts are versatile fasteners with a six-sided head, designed to mate with bolts for secure clamping. Their standardized geometry allows easy tightening with wrenches or sockets. Common materials include carbon steel (zinc-plated for rust resistance), stainless steel (304/316 for corrosion environments), and alloy steel. Strength grades (e.g., 4.8, 8.8, 10) define tensile resistance, while standards like DIN 934, ISO 4032, and ASME B18.2.2 specify dimensions (M3–M100) and thread types (metric/inch). The threaded interior creates preload force via mechanical engagement, often paired with washers to distribute pressure.
