Carton, palette ou selon les exigences du client
ASME B18.22.1 is the primary American national standard for plain, flat washers in the inch series. It defines the dimensional requirements and tolerances for washers intended for general industrial use, providing critical surface protection and load distribution for North American engineering specifications.
The standard distinguishes between Type A (precision-stamped for high performance) and Type B (general-purpose commercial grade), categorized into Narrow (N), Regular (R), and Wide (W) series to accommodate varying clearance and bearing surface requirements.
All ISO / DIN / ASME product pages will later be connected into a unified internal authority network after full product system completion.

ASME B18.22.1 washers are engineered for compatibility with American fastener sizes. Type A washers feature tighter tolerances on inner and outer diameters, making them ideal for high-stress aerospace and automotive applications. Type B washers offer more flexibility in general construction and machinery, available in multiple width series (Narrow/Wide) to fit specific design constraints.
