Frequently Asked Questions

AI
Metric bolts are measured in millimeters and are common in imported vehicles and electronics, while SAE (Standard) bolts use inches and are typical in domestic US hardware.
Stainless steel is ideal for outdoor or wet environments due to its rust resistance. Carbon steel, especially high-grade alloy, generally offers higher tensile strength for heavy-duty mechanical loads.
The grade number refers to the strength and hardness of the steel. A higher number typically indicates a bolt that can withstand more stress before failing or bending.
