Sure, you can use this table as a guide:
D [inch] | D [mm] | Safe Load [kN] |
---|---|---|
1/4 | 6.4 | 4.89 |
5/16 | 8 | 7.56 |
3/8 | 9.5 | 10.9 |
716 | 11.5 | 14.7 |
1/2 | 13 | 19.0 |
9/16 | 14.5 | 24.0 |
5/8 | 16 | 29.7 |
3/4 | 19 | 42.3 |
7/8 | 22 | 57.4 |
1 | 26 | 74.3 |
For 3/8" [9.5 mm], we have a safe load of 10.9 kN [1111 kg]
