Press-fit Nuts
We take an M4 stainless steel press fit nut as an example. We press it into a 1.2 mm thick SECC zinc coated sheet. The needed press force is about 2.5-4 kN. After installation, the push-out force is ≥180 N. The torque-out force is ≥2.0 N·m. The double chamfer design gives a pass rate of ≥99.5% on vibratory bowls and linear feeders.
Feed Smoothly in Auto Lines with Our Press Fit Nuts
Do you run an automatic assembly line? Regular press fit nuts get stuck in a vibratory bowl. Our Press Fit Nuts are made for auto lines. The serrations have a double chamfer. The nut orients itself in the feed track, no matter which side is up. It will not jam. We are a Shanghai factory. We have supplied fasteners for 20 years.
Check Our Feed Rate Data and Installation Force
We take an M4 stainless steel press fit nut as an example. We press it into a 1.2 mm thick SECC zinc coated sheet. The needed press force is about 2.5-4 kN. After installation, the push-out force is ≥180 N. The torque-out force is ≥2.0 N·m. The double chamfer design gives a pass rate of ≥99.5% on vibratory bowls and linear feeders. This works for auto press lines at 30-60 parts per minute. The size range is M2 to M12. The serration height is 0.25 to 0.45 mm. The hardness is HV 380-480. Thread precision is 6H. The nut length is 3.5 to 8.5 mm. This fits standard press tools. We offer stainless steel SUS304 and carbon steel 10B21. It works for 0.8 mm to 2.5 mm low carbon steel, zinc coated steel, and aluminum. It works for sheets with hardness ≤HRB 70. It does not work for stainless steel sheets. After installation, the nut face is flush with the sheet. The back has no bump (some types have a small bump for locating).
