Bolts and fixings play a crucial role in keeping bed frames sturdy and long-lasting. Whether you’re assembling a new bed or maintaining an existing one, understanding the most commonly used hardware is essential. In this guide, we’ll explore the most common types of bolts and fixings used in beds, and whether they follow metric or imperial measurements.
Most Common Bolts and Fixings Used in Bed Frames
1. Hex Bolts (Allen Bolts)
- Description: These bolts are often used for securing bed rails and frame components. They feature a hexagonal socket head, tightened using an Allen key (hex key).
- Measurements: Usually available in metric sizes (e.g., M6, M8, M10), though some manufacturers use imperial sizes (¼”, ⅜”).
2. Machine Screws
- Description: Used in metal bed frames for attaching support bars or brackets. They have a uniform thread and require nuts for secure fastening.
- Measurements: Typically metric, ranging from M4 to M8. Some older or custom-made beds might use imperial sizes.
3. Wood Screws
- Description: Essential for attaching wooden slats or brackets, these screws grip wood tightly without the need for nuts.
- Measurements: Usually metric in modern furniture (e.g., 25mm, 40mm lengths), but imperial sizes like 1″ or 1.5″ can still be found in traditional furniture designs.
4. Barrel Nuts & Cross Dowels
- Description: Used for strong connections in wooden bed frames, especially in flat-pack furniture. Barrel nuts allow bolts to tighten into a perpendicular cross dowel, improving stability.
- Measurements: Metric sizes (M6 or M8) are most common, but some brands might use imperial measurements.
5. Wing Nuts & Locking Nuts
- Description: Found in adjustable or collapsible bed frames, these allow for manual tightening or added security against loosening.
- Measurements: More commonly metric, but some designs, especially in North America, may use imperial sizes.
6. T-Nuts
- Description: Used for securing threaded bolts into wood, creating a reinforced anchor point for assembling bed frames.
- Measurements: Predominantly metric (M6, M8), though certain beds may use imperial equivalents.
Metric vs. Imperial: Which Is More Common?
Most modern bed frames, particularly those from European and Asian manufacturers, use metric measurements for bolts and fixings. Common metric sizes include M6, M8, and M10 for bolts and screws. However, bed frames designed in the United States or the UK may sometimes use imperial measurements, such as ¼”, ⅜”, or ½” bolts.
If you’re unsure about the sizing for your bed frame, checking the manufacturer’s manual or measuring existing fixings with a caliper can help determine whether metric or imperial hardware is needed.
