American Standard threaded rods are fully threaded fasteners compliant with U.S. specifications (ANSI, ASTM), designed for inch-based industrial systems in North America and global projects adhering to U.S. standards.
1. Core Features
Thread Standards:
UNC (Unified National Coarse): General-purpose for construction, machinery.
UNF (Unified National Fine): Precision threads for automotive, aerospace.
Dimensions:
Diameter: Common sizes 1/4″ (≈6.35mm) to 2″ (≈50.8mm); custom sizes available.
Length: Sold in feet/inches; customizable cuts.
2. Materials & Strength
Materials: Carbon steel (SAE Grade 2, 5, 8), stainless steel (304/316), alloy steel.
Strength Grades: Grade 5 (medium-high strength), Grade 8 (high strength), marked via head stamps or color codes.
Coatings: Hot-dip galvanizing, cadmium plating (corrosion resistance), phosphate coating.
3. Applications
Heavy Industry: Oil/gas pipelines, mining equipment, heavy machinery.
Automotive: Engine components, chassis fastening (SAE compliance).
Construction: Structural steel connections, bridge anchors (ASTM A193/A194).
4. Selection Tips
Compatibility: Pair with ANSI B18.2.2 nuts; avoid mixing with metric hardware.
Certifications: Critical sectors (nuclear, defense) require ASME or MIL-SPEC approval.
Regional Supply: Limited availability in metric-dominant markets; plan procurement.
Summary: U.S. Standard threaded rods are essential for North American industrial systems. Prioritize strength grades, corrosion resistance, and compliance with ANSI/ASTM specifications.
