M8 Carbon Steel Hot Dip Galvanized Security Shear Nut
The shear nuts is also a kind of nut. It has a bowl and a hex nut, combination. They are designed to be a permanent fixture after installation. The hexagonal part of the nut shears off at a pre-determined torque leaving only a tamperproof non-removeable cone. Available in either bright zinc plated steel (EN1A) or stainless steel (304).
Shear Nuts are available produced from A2 stainless steel, or from steel with zinc plated or hot dip galvanized, which is resiatant galvanized finish.

Application:
Shear Nut offer an inexpensive solution to many types of theft.
They are used to prevent the theft of the unanthorised relocation of seating or something.
They are installed by using standard tooling. When the nut or bolt is fully tighened, the hex drive head is designed to sgear off the additional torque is applied, leaving the sear bolt or the threaded conicak lower collar of the shear nut in position on the standard bolt or stud thread, so making the products permanent fixed.
