5/8" Inorganic Zinc Silicate L7 Stud Bolt Kit

Inorganic Zinc Silicate (IZS) provides excellent corrosion resistant properties providing fasteners with extended service life in harsh environments, and can be specified as a primer for a multiple finish high-build systems.

Particularly ideal for high corrosive coastal environments, IZS provides superior galvanic corrosion protection when compared with hot-dipped galvanising. Used on studbolts for off-shore platforms it is often referred to as "Esso Spec" within the fastener industry.

Stud lengths are measured first leading thread to last leading thread.
All kits are supplied with 2 heavy hex nuts.
ASTM A193/A194 stud bolts and nuts come standard with EN 3.1 certification.
