Nat Cakera Dua-Tonjol
A pressed steel disc nut with two ears for tool-free hand tightening. The two lugs give extra leverage on site and make assembly faster; the disc face spreads load against the waler or panel. Used with D15 / D20 formwork tie rods.
Spesifikasi
- Two-lug pressed steel construction
- Fits D15 / D20 tie rod threads
- Hand-tight leverage without tools
- Pairs with waler and panel clamping

| Grade | Catatan |
|---|---|
| Q235 | Plain carbon steel. Economic option for light and medium formwork loads. Not heat treated. |
| 45# | Medium carbon steel. The standard formwork tie rod grade in China; quenchable to class 8.8. |
| 40Cr | Alloy steel. Higher hardenability and better fatigue performance than 45#; used where repeated reuse matters. |
| Class 10.9 bolt | Quenched and tempered alloy steel bolt used in the climbing cone set. Not electroplated without a documented baking cycle. |
| QT450-10 | Ductile (nodular) iron with 450 MPa tensile and 10% elongation. Used for sleeves and embedded plates where toughness and castability matter. |
| HRB400 | Hot-rolled ribbed bar (threaded steel) to Chinese standard. Used for embedded foot bolts; good bond with concrete. |

Nat Cakera Dua-Tonjol — Jawapan untuk Jurutera dan Pembeli
D15 and D20 refer to the nominal bar diameter (about 15 mm and 20 mm). At the same steel grade, tensile capacity scales with cross-sectional area, so a D20 bar carries roughly 1.7 to 1.8 times the load of a D15. D15 is typical for residential slabs and light walls; D20 is used for thicker walls, higher pour rates and heavier hydrostatic loads. Final selection must always be checked against the formwork pressure calculation for the specific pour height and rate.
