This blog post covers a detailed Bolt Weight Chart to assist in calculating accurate weight for shipping, inventory, and engineering applications.
Why Bolt Weight Matters
Knowing the weight of bolts is important in many industrial and commercial operations. From transport logistics to structural design, the weight per piece or per 1000 pieces is critical. Factors influencing weight include diameter, length, and material (usually carbon steel, stainless steel, or alloy).
Below are standard weight charts for Hex Bolts, Eye Bolts, and Carriage Bolts, commonly used across multiple sectors like construction, automotive, and heavy machinery.
Table 1: Hex Bolt Weight Chart (Mild Steel – per 100 pieces)
Bolt Size (mm) | Length (mm) | Approx Weight (kg) |
M6 | 20 | 0.84 |
M8 | 30 | 2.10 |
M10 | 50 | 4.70 |
M12 | 75 | 9.60 |
M16 | 100 | 17.00 |
M20 | 120 | 28.50 |
These hex bolts are widely used in industrial machinery and metal structures. The weight here helps in estimating bulk packaging and shipping costs.
Table 2: Eye Bolt Weight Chart (per piece, Stainless Steel)
Eye Bolt Size | Shank Length (mm) | Weight (grams) |
M6 | 50 | 60 |
M8 | 75 | 120 |
M10 | 100 | 220 |
M12 | 125 | 360 |
M16 | 150 | 600 |
Eye bolts are used for lifting, rigging, and anchoring. These are especially common in marine and construction industries.
Table 3: Carriage Bolt Weight Chart (Galvanized – per 100 pcs)
Diameter (inches) | Length (inches) | Weight (kg) |
1/4" | 2" | 1.20 |
5/16" | 3" | 2.50 |
3/8" | 4" | 4.00 |
1/2" | 5" | 6.80 |
5/8" | 6" | 11.20 |
Carriage bolts are often used in wood-to-metal or wood-to-wood applications where a smooth, rounded head is needed for aesthetics or safety.
