Technical specification
Materials and finishes
Information based on ESHUA fastener catalogs. For critical applications, validate grade, standard, lot and certificate before manufacturing or installing.
Materials
Choose by corrosion resistance, conductivity, insulation or mechanical performance.
Stainless 304 / 316 / 410
Corrosion resistance for industrial, moderate outdoor, and special applications.
Brass
Copper and zinc alloy for electrical connections, plumbing, and visible finish.
Silicon bronze
Good mechanical and corrosion resistance in wet or marine environments.
Nylon
Lightweight and insulating for washers, nuts, cable ties, and spacers.
Plastic
Lightweight, economical, and moisture resistant for plugs, anchors, and light fasteners.
Aluminum
Good strength-to-weight ratio for machined parts, plates, and special components.
Carbon steel and alloys
High mechanical strength for construction, machinery, and structures.
Finishes
Protection, appearance and performance for each environment.
Selection criteria
The right finish depends on the real working environment.
Humidity, chemicals, heat, electrical conductivity, aesthetic requirements and maintenance frequency can change the recommended option.
Not sure which finish to use?
Share the working environment, base material, size and reference photo/drawing.
