[250 lb breaking strength]: Rated tensile strength of 250 lb – not a lightweight cable tie. Securely fastens exhaust pipe wrapping, heavy-duty cable bundles and farm fencing. [Vibration-Resistant]: Inside the buckle, a stainless steel ball wedges the strap body. The ball remains secure even under engine vibration and thermal cycling – it will never loosen. [2-in-1 Tightening and Cutting Tool]: The optional metal cable tie tool tightens the strap and flush-cuts the end in a single action. The cable tie remains under full tension during trimming – no loss of tightness. The cut is clean, with no sharp burrs. [Saltwater Resistant]: 304 stainless steel withstands sea spray, road salt and similar conditions. Trusted by offshore platforms, chemical plants and coastal facilities. [Flame-Retardant and Heat-Resistant]: Metal cable ties will not burn or contribute to fire – safe for use near exhaust pipes or high-heat equipment., Manufacturer: AURVIX
