Flexbar Rocksett is an all-purpose engineering adhesive ceramic cement that delivers exceptional performance in demanding gunsmithing and mechanical assembly applications. With incredible temperature resistance ranging from -350°F up to 2,015°F, this heat resistant threadlocker is built for high temperature environments, yet fully removable with a simple hot water soak—making it ideal for securing muzzle devices, suppressors, and other threaded firearm components without permanent bonding.
Rocksett locks, seals and bonds nuts, screws, shafts, keys, splines, pipes, flanges, and more, while bonding ceramic, glass, metals, and even keyless surfaces. Rocksett withstands oil, fuels, acids, and alkalis, providing reliable chemical resistance for harsh environments. The formula is non-toxic, odorless, and non-flammable, and requires no mixing or priming before application.
This 2-ounce bottle includes a precision dropper for controlled application on threaded fasteners and assemblies. Unlike standard threadlockers that require heat guns or brute force to remove, Rocksett lets you secure fasteners with confidence and still service them without damage. Perfect for gunsmith shops, armorers, and serious firearms enthusiasts who demand performance without compromise.
