M22 Anchor Bolt Weight Chart
Per-piece weights of M22 anchor bolts in four configurations — straight, J-hook, L-bend and welded end plate — across the full length range (carbon steel, geometric-volume method), kg and lb, basis fully disclosed.
A M22 J-hook anchor bolt (500 mm shank + hook developed length 6d, carbon steel 7.85 g/cm³) weighs about 1.9 kg per piece; the straight pattern about 1.5 kg — full length table below.

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
All values are computed as geometric volume × density (carbon steel 7.85 g/cm³, base metal, coating excluded) — no copyrighted standard tables are reproduced. 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, unwelded-hole-free plate, weld and accessories excluded). The full nominal diameter is used along the shank with no thread reduction.
Boundary: theoretical geometric estimates for quotation, freight and lifting budgets. Actual piece weight varies with the as-built configuration (hook/leg/plate per drawing) and coating (hot-dip galvanizing ≈ +4.5%). Use measured values for trade settlement; send drawings for non-standard configurations.

FAQ
How much does an M22×500 J-hook anchor bolt weigh?
On the carbon-steel basis (500 mm shank + hook developed length 132 mm = 6d, full diameter) about 1.9 kg per piece. The straight pattern runs about 1.5 kg and the L-bend (leg 88 mm = 4d) about 1.8 kg — see the full length table above.
What is the difference between J-hook and L-bend M22 anchor bolts?
In this chart only the developed add-on differs: J-hook at 6d (+132 mm, GB/T 799 hooked-bolt basis) versus an L-bend leg at 4d (+88 mm, explicit assumption). At L=500: J-hook ≈ 1.9 kg, L-bend ≈ 1.8 kg. Actual hook/leg dimensions follow the drawing.
How is the weight of a M22 anchor bolt with end plate calculated?
Shank weight plus plate weight. The plate is a 88×88×11 mm square (a=4d, t=0.5d, explicit assumption, hole-free welded plate): at L=500 the assembly is about 2.2 kg per piece. For other plate thicknesses, holes or stiffeners, request a quotation to drawing.
What basis are these weights calculated on?
Geometric volume × density (carbon steel 7.85 g/cm³, base metal, coating excluded) — the same formulas as our catalog SKU weights; full nominal diameter with no thread reduction; hook/leg/plate parameters fully disclosed in the basis section. Theoretical estimates — use measured values for trade settlement.
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 M22 nominal diameter.
