Regarding Quality

 For off-the-shelf products: You can directly provide standard specifications (e.g., size, material, surface treatment).
For custom non-standard carriage bolts: Please supply drawings (formats: CAD, PDF, STP) or samples, clearly noting the order quantity, material precision, tolerance requirements and special surface treatment needs. You can send the information to our customer service when inquiring.
 

Product specifications (size, head type, thread length);
Material type (e.g., carbon steel, stainless steel, alloy steel);
Order volume and surface treatment (e.g., galvanizing, passivation).
We will offer reasonable and competitive prices, while balancing product quality, delivery time and service—instead of simply pursuing the lowest price, we focus on delivering cost-effective solutions for your carriage bolt needs.

Our carriage bolts strictly comply with industry standards (e.g., ISO, DIN). During production, we conduct multiple inspections targeting carriage bolt characteristics:
 Dimensional accuracy testing (especially head diameter, shank smoothness, thread fit);
Tensile strength & shear strength testing (matching carriage bolt's load-bearing scenarios);
Salt spray rust-proof testing (for corrosion resistance of surface-treated bolts);
Head tightness inspection (to ensure the round head and square neck fit stably).
