Material Density Conversion
Values above are carbon steel (7.85 g/cm³); for other materials multiply by the density factor.
| Material | Density (g/cm³) | Factor |
|---|---|---|
| Carbon / Alloy Steel | 7.85 | ×1.000 |
| Stainless 304 | 7.93 | ×1.010 |
| Stainless 316 | 7.98 | ×1.017 |
| Brass | 8.5 | ×1.083 |
Basis of Calculation & Disclosed Assumptions
Calculation basis
- All values are computed size by size as geometric volume × density (carbon steel 7.85 g/cm³, base metal, coating excluded) — identical formula and parameters as the online weight calculator.
- Straight = cylinder π/4·d²·L; J-hook = shank + hook developed length 6d (GB/T 799 hooked-bolt basis, identical to the online calculator).
- L-bend = shank + leg 4d (explicit assumption — GB/T 799 has no L-type leg table); with-plate = shank + square plate a×a×t (a=4d, t=0.5d, explicit assumption, hole-free plate, weld and accessories excluded).
- The full nominal diameter is used along the shank with no thread reduction.
Scope & limits
- Theoretical geometric estimates for quotation, freight and lifting budgets; use measured values for trade settlement.
- Actual piece weight varies with the as-built configuration (hook/leg/plate per drawing) and coating (hot-dip galvanizing ≈ +4.5%); send drawings for non-standard configurations.
- Theoretical estimate tolerance ±5%.

FAQ
What is the difference between J-hook and L-bend M33 anchor bolts?
In this chart only the developed add-on differs: J-hook at 6d (+198 mm, GB/T 799 hooked-bolt basis) versus an L-bend leg at 4d (+132 mm, explicit assumption). At L=500: J-hook ≈ 4.69 kg, L-bend ≈ 4.24 kg. Actual hook/leg dimensions follow the drawing.
Are anchor bolts, foundation bolts and J bolts the same thing?
They are names within one product family: "anchor bolt" and "foundation bolt" both denote bolts embedded in a concrete foundation; a "J bolt" is the pattern with a J-shaped hook at the embedded end (the J-Hook column of this chart, hook developed length 6d), while an "L bolt" carries an L-shaped leg (the L-Bend column). All four configurations here are computed geometrically at the M33 nominal diameter.
