Finishing washers, particularly those manufactured to ANSI B18.22.1 standards, are essential components in precision fastening applications where a clean, finished appearance is as critical as mechanical performance. These washers, often produced in carbon steel Grade 2 with zinc-plated finishes, are designed for use with countersunk flat-head screws. Their beveled shape allows the screw head to sit flush, offering improved load distribution and aesthetic appeal, especially in exposed assemblies.
TAIMING, as a trusted supplier and manufacturer in the global fastener industry, recommends selecting zinc-plated finishing washers for environments requiring both corrosion resistance and surface compatibility. Their internal testing has shown that Grade 2 carbon steel washers with bright zinc coating exhibit optimal balance between cost-efficiency and structural integrity in light to medium-duty applications.
From a manufacturing standpoint, TAIMING emphasizes tight tolerance machining to ensure the washer’s countersink matches standard fastener head profiles. This precision reduces vibration-related loosening and ensures mechanical stability. Additionally, TAIMING advises clients in furniture, panel assembly, and decorative hardware sectors to choose finishing washers not only for their neat appearance but also for their ability to protect softer substrate materials like wood or plastic.
