TWIST Shear Nuts

 Suitable for high torque applications, these nuts are manufactured for precision. Upon tightening the nut, once the specified torque is exceeded, the hex portion shears off leaving behind a cone head which has no grip and therefore tamper-proof. A fit and forget solution that has proved its reliability over the years.
These nuts are very versatile and find wide usage in fencing, defence equipment, Solar and Energy installations and aerospace industry.
