Insultwist Studs & Lock Washers: Secure Fastening Solutions for High-Temperature Insulation Systems
In high-temperature industrial environments, the reliability of insulation and refractory systems depends not only on the insulation material itself but also on the fastening method used. Insultwist Studs and Lock Washers are specially designed fastening solutions that provide secure, vibration-resistant fixing for insulation materials exposed to extreme heat and mechanical stress.

What Are Insultwist Studs and Lock Washers?
Insultwist Studs are threaded metallic fasteners welded or mechanically fixed to equipment surfaces to hold insulation materials in place. Lock Washers, used in combination with these studs, provide additional grip and prevent loosening caused by vibration, thermal expansion, or operational movement.
Together, they form a robust fastening system for high-temperature insulation and refractory applications.
