WCS Lock Wire Review: T302/304 Stainless Steel – A Reliable Safety Solution

Safety wiring, also known as lock wiring, is a crucial technique for securing fasteners in applications where vibration or movement could cause them to loosen. The WCS WIRE AND CABLE SPECIALTIES, INC. Lock Wire, manufactured to meet rigorous standards like NASM20995, MS20995C, ASTM A580 Cond A, and AMS5697, offers a reliable solution for preventing such failures. This review takes a close look at this stainless steel lock wire to assess its performance, usability, and overall value.

This specific lock wire is designed for use in aerospace, automotive, marine, and other demanding applications where fastener security is paramount. From securing bolts on aircraft engines to ensuring the integrity of braking systems, lock wire provides an extra layer of protection against accidental loosening.

Key Features

  • Material: T302/304 Stainless Steel: Offers excellent corrosion resistance and durability, making it suitable for harsh environments.
  • Standards Compliance: Meets NASM20995, MS20995C, ASTM A580 Cond A, and AMS5697 standards, ensuring quality and reliability.
  • Dimensions: .041 in (1.04 mm) diameter wire, providing a balance of strength and flexibility.
  • Packaging: 1 lb (0.45 kg) dispenser can for easy handling and storage.
  • Length: Approximately 221 ft (67 m) of wire per can, offering ample material for multiple applications.

Pros

  • Exceptional Corrosion Resistance: The T302/304 stainless steel construction ensures excellent resistance to corrosion, making it ideal for use in demanding environments where exposure to moisture, chemicals, or salt spray is a concern. This ensures a long service life and reliable performance.
  • High Tensile Strength: The wire exhibits impressive tensile strength, providing a secure and reliable locking mechanism for fasteners, even under vibration and stress. Its ability to maintain its integrity under pressure ensures critical components remain securely fastened.
  • Easy to Use Dispenser Can: The dispenser can simplifies handling and prevents tangling of the wire. This feature saves time and effort, particularly in fast-paced work environments.
  • Meets Stringent Standards: Compliance with NASM20995, MS20995C, ASTM A580 Cond A, and AMS5697 guarantees that the wire meets or exceeds industry requirements for quality and performance, providing peace of mind.

Cons

  • Potential for Sharp Edges: As with any wire, care must be taken to avoid cuts or abrasions from sharp edges, especially when cutting and twisting the wire. Gloves are highly recommended for safe handling.
  • Price Point: While the $20.99 price point is reasonable, cheaper alternatives exist if standards compliance isn't a strict requirement. However, those alternatives may not offer the same level of quality or corrosion resistance.

FAQs

Q: What is the difference between T302 and T304 stainless steel?

A: Both T302 and T304 are austenitic stainless steels known for their corrosion resistance. T304 contains slightly more chromium and nickel, making it slightly more resistant to corrosion. They are often used interchangeably.

Q: What tools do I need to use lock wire?

A: You will need lock wire pliers (also known as safety wire pliers) for twisting and cutting the wire. You may also need safety glasses and gloves for protection.

Q: How do I know if the lock wire is properly installed?

A: The wire should be twisted tightly and in the correct direction so that any tendency of the fastener to loosen will tighten the wire. The ends of the wire should be neatly trimmed and tucked away to prevent snagging or injury.

Q: Can I reuse lock wire?

A: No, lock wire should never be reused. Once it has been twisted and cut, it loses its integrity and may not provide adequate security.

Q: Where can I find comparable lock wire?

A: You can find similar lock wire from brands like Mil-Spec Monkey or Loos & Co., but be sure to verify that they meet the required specifications for your application.

Honestly disappointed. One of the gears was slipping right out of the box and the screws they include are super soft, stripped two of them immediately even with a pilot hole. Spend the extra money on something better if you actually care about your instrument.
