Frequently Asked Questions
What's the difference between machine screws and bolts?
Machine screws are designed to thread directly into pre-tapped holes or secure with a nut, and are typically smaller with finer threads than bolts. They're used primarily for precision assembly work rather than structural fastening applications.
Are Sirius machine screws suitable for outdoor applications?
Sirius offers machine screws in various finishes including zinc plated and stainless steel options. For outdoor use, we recommend selecting stainless steel variants or appropriately coated screws to ensure adequate corrosion resistance in exposed conditions.
How do I select the correct thread size?
Machine screw threads must match your pre-tapped hole or nut specification. Metric threads are designated by diameter (e.g., M4, M5), whilst imperial sizes use gauge numbers or fractional inches. Always verify thread pitch compatibility for critical applications.
