Ensure the .021 inch (0.53 mm) diameter is appropriate for your specific application's fastener size and vibration requirements. Consult project specifications or tool guides if unsure. — Select Correct Wire Diameter 2. Unwind the required length from the 5 lb dispenser can, controlling the pull to avoid tangling. Cut the wire cleanly using safety wire pliers or appropriate cutters. — Prepare and Cut Wire 3. Thread the wire through the designated holes in the fasteners (e.g., bolt heads and shank). Use safety wire pliers to twist the wire ends together tightly and securely, creating a strong lock that resists vibration. — Twist Wire Securely 4. After twisting, trim any excess wire ends to prevent snagging. Ensure the twisted wire is tight and the ends are properly secured or bent to avoid interference with other components. — Trim and Secure Ends ## Product details | Field | Value | |---|---| | Primary Material | Stainless Steel (T302/304 Alloy) | | Key Properties | Corrosion-resistant, Rust-resistant, Oxidation-resistant, High tensile strength | | Recommended Use | Securing nuts, bolts, and hardware subject to vibration in aircraft, automotive, motorsport, and industrial applications. | | Installation Method | Works with standard safety wire clamp tool setups and aviation safety wire pliers. | | Cost per meter | {{ccc_price_per_unit:4200:foot}} (approx. 4200 ft per 5 lb spool) | | Shelf life after opening | Indefinite when stored in dispenser can, protected from moisture. | | Contraindications | Not recommended for food contact applications unless certified; not suitable for jewelry making if a softer, more pliable wire is needed. | | Allergens / common irritants | Nickel (trace amounts in stainless steel) | | Brand | WCS WIRE AND CABLE SPECIALTIES, INC. | | Product Name | WCS .021 Stainless Steel Safety Lock Wire | | Alloy Grade | T302/304 | | Diameter | 0.021 inches (0.53 mm) | | Length | Approx. 4200 ft | | Weight | 5.35 lbs (2.43 kg) | | Material | Stainless Steel | | Finish | Polished | | Compliance Standards | NASM20995C, MS20995C, ASTM A580 Condition A, AMS5697 | | Item Form | Coil in Dispenser Can | | Country of Origin | Not stated by manufacturer — US retail version, sourced from authorized US retailers | ## Attributes - **Item form:** Coil ## Frequently asked questions ### How to buy original WCS .021 Stainless Steel Safety Lock Wire in India?

This WCS wire is 304 grade, suitable for general industrial and automotive use. ### How do I know which gauge or diameter to order for my project? The WCS wire is .021 inches (0.53 mm) in diameter, suitable for many standard safety wire applications. For other needs, WCS offers diameters from .020 to .063 inches. Consult your project specifications or tool manual to determine the correct gauge for your specific requirement. ### Is this wire suitable for aircraft and automotive applications? Yes, this WCS .021 Stainless Steel Safety Lock Wire is manufactured to NASM20995C, MS20995C, ASTM A580 Condition A, and AMS5697 standards, making it suitable for regulated aviation, automotive, and industrial use where vibration security is critical. ### Can this wire be used in marine or coastal environments? While T304 stainless steel offers good corrosion resistance, it is not as robust as 316 grade in highly corrosive marine or coastal environments. For prolonged exposure to salt spray or harsh chemicals, consider a 316 stainless wire if available, though this 304 grade is suitable for many outdoor and humid Indian conditions. ### How long will this wire last in use? When used correctly for its intended purpose of securing fasteners against vibration, this stainless steel wire is designed for long-term performance. Its corrosion resistance means it will not rust or degrade easily in typical shop, garage, or industrial settings, ensuring continued security over time. ### What is the best way to use safety lock wire? Safety lock wire is typically used to secure nuts, bolts, and hardware subject to vibration. It is twisted around the components using specialized safety wire pliers or clamp tools to prevent loosening. This .021 inch wire is engineered for consistent diameter and flexible handling to reduce snapping during installation. ### Does this wire come with a dispenser? Yes, this 5 lb spool of WCS Stainless Steel Safety Lock Wire comes in a convenient dispenser can. This design helps control the wire pull, reduces tangling, and supports an organized workflow for garages, industrial maintenance, and professional applications. ## Compliance No product-specific compliance warnings identified.
