Recommended Installation Torque
Below are the recommended installation torque values for various Beswick fitting sizes. Please note, these are general guidelines only and they assume that you are threading the fitting into a mating port of equal strength. If the fitting is being threaded into a weaker material, such as acrylic, you may have to reduce the installation torque accordingly.

|---|---|---|
| M3x0.5 † | 4-6 lbf*in (0.45-0.68 N*m) | 4-6 lbf*in (0.45-0.68 N*m) |
| M4x0.5 | 4-6 lbf*in (0.45-0.68 N*m) | 4-6 lbf*in (0.45-0.68 N*m) |
| 10-32 † | 7-9 lbf*in (0.79-1.02 N*m) | 9-12 lbf*in (1.02-1.36 N*m) |
| M5x0.8 † | 7-9 lbf*in (0.79-1.02 N*m) | 9-12 lbf*in (1.02-1.36 N*m) |
| M6x1.0 | 7-9 lbf*in (0.79-1.02 N*m) | 9-12 lbf*in (1.02-1.36 N*m) |
| 1/4-28 | 7-9 lbf*in (0.79-1.02 N*m) | 9-12 lbf*in (1.02-1.36 N*m) |
