DIN 933 Wheel Stud Bolts | Automotive wheel assemblies, machinery | Thread size M12–M27 (DIN 933), tensile strength 6.8–8.8 (▲ over ISO 898-1 base) | Ensures compatibility with European standards; precise fit for high-vibration applications | Limited thread size range; requires exact nut pairing (e.g., M12 ▲ for trucks vs M10 for lighter vehicles) |
Stainless Steel Bolts | Marine, food processing, corrosive environments | AISI 316 stainless steel (ASTM A193), 1,000hr salt spray resistance (▲ vs 500hr industry avg) | Immune to rust in harsh environments; ▲ chemical resistance (ASTM F1561) | Lower tensile strength (570 MPa) vs carbon steel; costlier (▲ premium price tag) |
High-Strength Carbon Steel | Heavy machinery, structural engineering | Grade 10.9 (ISO 898-1), yield strength 940 MPa (▲ 40% over DIN 933 base) | ▲ Load-bearing capacity (e.g., 150mm length ▲ for bridge joints) | Prone to corrosion without coating; requires frequent inspection (▲ maintenance cost) |
ANSI Standard Bolts | North American construction, HVAC | Thread pitch per ANSI B1.1, material ASTM A307 (▲ 20% cost efficiency) | Widely available in U.S. markets; ▲ ease of procurement (▲ 30% stock availability) | Lower strength (410 MPa) vs metric standards; limited to M10–M24 (▲ smaller range) |
ISO Standard Bolts | Global industrial, automotive | Thread tolerance ISO 261, material ISO 898-1 (▲ 25% precision over ANSI) | Universal compatibility across regions; ▲ precision fit (e.g., M20 ▲ for engines) | Higher cost due to precision manufacturing; ▲ 15% lead time vs local standards |
Heavy-Duty Hex Bolts | Construction, heavy equipment assembly | Diameter up to M27 (ISO 4014), yield strength 830 MPa (▲ 30% over ANSI base) | Supports extreme loads (e.g., 150mm ▲ for crane assemblies) | Bulky design limits space-constrained applications; ▲ 20% installation difficulty |
