Japanese Nitto Seiko Successfully Develops New Clinching Stud Bolts
Add to my favorite
Clinching stud bolts are commonly used in the automotive industry. Pressing clinching stud bolts into materials often causes materials to warp or develop burrs which impacts the precision and quality of products. Nitto Seiko's new clinching stud bolts can reduce warping and burrs and further decrease spinning. The inside of the lobe-shaped protruding part has a concave to house the deformed material. The deformed portion will stick out towards the male threads to prevent burrs as well as spinning. The product is pending for patent. The company is set to produce 1 million pieces per month.
