Its T302/304 stainless steel composition offers superior resistance to rust and oxidation, making it ideal for India's diverse climates, from coastal humidity to industrial heat. Unlike generic wires, it meets strict NASM20995C and ASTM A580 standards, ensuring it performs reliably when securing critical fasteners in aircraft, automotive, and industrial settings. The engineered twist provides flexibility, reducing installation issues and ensuring long-term tension. **Ideal for Secure Fastening, Not for General Craft** — This wire is specifically designed for high-stress applications like securing bolts and nuts in vibrating machinery, aircraft components, and automotive parts. It excels where standard fasteners might loosen. It is not intended for jewelry making, general crafting, or decorative purposes due to its industrial strength and finish. For everyday home repairs or light-duty tasks, consider simpler galvanized wires. This product is best suited for professionals and serious DIYers requiring certified, high-tensile strength. ## How to use 1. Unspool approximately 18-24 inches (45-60 cm) of the WCS .041 stainless steel safety lock wire from the 1 lb dispenser. Ensure the wire is free of kinks or damage. Cut the desired length using appropriate wire cutters. — Prepare the Wire 2. Thread the wire through the holes of the fasteners (nuts, bolts) you need to secure. Twist the two ends of the wire together tightly using safety wire pliers or a manual twisting technique, ensuring a snug fit against the components. — Thread and Twist 3. Continue twisting until a firm, secure lock is achieved. Trim any excess wire, leaving about 1/2 inch (1.27 cm) of the twisted end. Bend the trimmed end back to prevent snagging or loosening, ensuring a permanent and vibration-resistant lock. — Secure the Twist ## Product details | Field | Value | |---|---| | Alloy | T302/304 Stainless Steel | | Compliance Standards | NASM20995C, MS20995C, ASTM A580 Condition A, AMS5697 | | Recommended Uses | Securing fasteners against vibration in aircraft, automotive, industrial, and workshop settings. | | Installation | Works with standard safety wire clamp tools and pliers. | | Cost per use | 221 ft (67.36 m) spool at ~1 ft/use = ~221 uses: ₹14.02 per use | | Shelf life after opening | Indefinite (when stored properly) | | Contraindications | Not suitable for jewelry making, general craft, or decorative purposes. | | Allergens / common irritants | May contain Nickel Metallic (California Proposition 65 warning) | | Brand | WCS WIRE AND CABLE SPECIALTIES, INC. | | Part Number | MC0410-1#D | | Material | T302/304 Stainless Steel | | Finish Type | Polished | | Color | Silver | | Diameter | 0.041 inches (1.04 mm) | | Length | 221 feet (67.36 m) | | Weight | 1 lb (0.45 kg) | | Item Form | Coil in Dispenser | | 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 .041 Stainless Steel Safety Lock Wire in India?

This product is safety lock wire, not standard wire rope. Safety lock wire, like this WCS .041 model, is typically a single twisted strand designed for securing fasteners against vibration. Standard wire rope construction (7x7 or 7x19) refers to multiple strands twisted together, offering flexibility for lifting and pulling applications. ### Which finish should I choose for outdoor lifting use? This WCS lock wire is made of T302/304 stainless steel, offering excellent corrosion resistance for outdoor and humid environments. For lifting applications, consider the specific requirements: galvanized steel offers basic rust protection, while stainless steel provides superior resistance to corrosion, making it ideal for coastal or wet conditions. Vinyl-coated options add abrasion resistance. ### Is this wire suitable for aircraft and automotive applications? Yes, this WCS .041 Stainless Steel Safety Lock Wire is specifically designed and manufactured to meet NASM20995C, ASTM A580 Condition A, and AMS5697 standards, making it suitable for regulated aviation, automotive, and industrial use where secure fastening against vibration is critical. ### Can I use this wire for general DIY or craft projects? While versatile, this wire is engineered for high-stress industrial applications like securing fasteners in vibrating machinery. It is not recommended for jewelry making or general craft projects due to its industrial strength and finish. For such uses, consider softer, more pliable craft wires. ### How does the 1 lb dispenser help with installation? The 1 lb dispenser can allows for a controlled pull of the wire, preventing tangling and reducing frustration during installation. This organized workflow is beneficial for both professional mechanics and DIY enthusiasts, ensuring the wire is ready when needed and easy to manage. ### What are the benefits of stainless steel wire for Indian conditions? Stainless steel, particularly T302/304 alloy, offers excellent resistance to rust and oxidation, which is crucial in India's humid coastal regions and during monsoon seasons. This ensures the wire maintains its integrity and secure fastening capabilities over time, even in demanding outdoor or high-temperature environments. ## Compliance No product-specific compliance warnings identified.
