What are Tri-Head Key Wrenches?
A widely used vandalism deterrent fixing, this type of security screw is commonly used in public installations and can often be found in lamp posts and other external street lighting fittings.
As all Tri Head Security Screws in this range are produced to the M8 metric coarse thread size, the same sized Tri Head Wrench Key can be used for all length variations of this screw.
