Frequently Asked Questions

AI
Stainless steel is ideal for environments exposed to moisture due to its corrosion resistance. Carbon steel, especially higher grades, typically offers greater shear strength for heavy-duty mechanical applications.
Fully threaded bolts have threads along the entire shaft, allowing them to be tightened in thicker materials. Partially threaded bolts have a smooth shank, which is often stronger and better for specific joint alignments.
Check your existing hardware or the manufacturer's specifications. Metric bolts (M4, M6, etc.) are standard for most modern electronics and imported machinery, while imperial (SAE) are common in older US-made equipment.
