M27 Anchor Bolt Sizes & Grades
GB/T 799-2020 lists anchor bolt sizes in stepped values from M8 to M72 (M8/M10/M12/M16/M20/M24/M30…); M27 is not among the listed sizes, so every M27 anchor bolt here is custom — length, hook bend radius, leg length, end plate and coating per project drawing. Common property classes for anchor bolts are 4.6 and 8.8 carbon steel with hot-dip galvanized coating per ISO 898-1 / GB/T 3098.1; embedded depth and bend geometry follow the structural drawing and anchorage design.
For tightening, torque depends on grade and friction state — e.g. class 8.8 electro-zinc ≈ 944 N·m (833–1110), hot-dip galvanized ≈ 1221 N·m (K 0.18–0.25) — see the M27 bolt torque chart for the full class × friction matrix.

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 M27 anchor bolts?
In this chart only the developed add-on differs: J-hook at 6d (+162 mm, GB/T 799 hooked-bolt basis) versus an L-bend leg at 4d (+108 mm, explicit assumption). At L=500: J-hook ≈ 2.98 kg, L-bend ≈ 2.73 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 M27 nominal diameter.
