304 Stainless Steel These stainless steel zip ties are made from 304 stainless steel for corrosion resistance and dependable outdoor use. They offer a metal alternative to nylon ties for fastening projects exposed to sun, rain, vibration, and changing temperatures. Secure Self Locking These metal zip ties feature a roller-ball buckle: thread the strap through, pull snug, then release slightly so the lock can seat. The one-way design helps keep fences, pipes, cables, and wraps firmly bundled. 24 Inch Size These stainless steel cable ties measure 24 x 0.18 x 0.01 in (600 x 4.6 x 0.25 mm) and fit bundles up to about 3.5 in in diameter. The 300-pack quantity suits large projects and ongoing repairs. Tool Friendly Setup Start by hand, tighten with needle-nose pliers or a stainless steel zip tie tool, and trim with tin snips. Wear work gloves and flatten or fold the cut tail; tensioning tool is not included. Wide Applications Use these heavy duty zip ties for chain link fence repair, chicken wire, garden mesh, exhaust wrap, HVAC, pipes, signs, solar cable routing, and general outdoor cable management. Their sturdy metal construction helps resist chewing by puppies and other sharp-toothed animals
