40S41-8SC

The part you originally want 40S41-8SC is made of high strength stainless steel which has a tension force of 4700N and 3100N working load and comes with a large springcup. We suggest to switch an alternative also made in stainless steel however with a tension load of 3300N and working load of  2200N and a small spring cup which is part HGRTLC-8S which requires the use of a retaining washer MHSWSS. If you need absolutely the high force, then switch to the steel zinc plated part which has also 4700N tension force which is part HGRTLC-8Z with small spring cup or we can also suggest the part HGRTLC-8HSS, which is also made in high strength stainless steel but with large spring cup.
