The VALUE COLLECTION 34-0250-1BLC is a stainless steel safety lock wire used to secure fasteners, fittings, and critical hardware against vibration-induced loosening. Manufactured from 302/304 stainless steel to ASTM A580 standards, this wire measures 0.025 inches in diameter and provides 595 feet per pound of usable length. Safety lock wire is a standard mechanical retention method in HVAC, refrigeration, plumbing, and industrial service work where fasteners must remain torqued under continuous vibration or thermal cycling. Each package contains one spool weighing approximately 1 pound.
This lock wire is suited for residential and commercial applications where stainless steel is required for corrosion resistance. Common uses include securing bolts on compressors, valve bonnets, pump flanges, and mechanical equipment panels. The 0.025-inch diameter is a widely used size for general-purpose safety wiring on small to medium fasteners. Technicians in HVAC, refrigeration, and mechanical contracting regularly use this wire size with standard safety wire pliers during equipment installation, inspection, and maintenance work.
Designed as a general-purpose safety lock wire for use on standard fasteners in HVAC, refrigeration, plumbing, and mechanical industrial applications requiring stainless steel wire retention.
Safety lock wire is installed by licensed HVAC technicians, refrigeration mechanics, plumbers, and industrial service professionals. Power down and de-energize all equipment before accessing fasteners. Use proper safety wire pliers to twist and tension the wire consistently without over-stressing the wire at the bend points. Follow applicable equipment manufacturer guidelines and service codes when applying safety wire to pressurized or high-temperature systems.
