Aerospace Safety Locking Wire - Knight Group

Aerospace Locking Wire

Ensure Ultimate Safety & Reliability with our Premium Aerospace Locking Wire for High-Stress Environments

Aerospace locking wire, also known as safety lock wire, is a soft annealed wire used to secure nuts, bolts, and components in aerospace, marine, automotive, and industrial sectors. It prevents fasteners from shaking loose or falling out due to wear and tear, vibration, and corrosion. The wire is made of malleable stainless steel or nickel alloy, passed through small holes on the fastener, looped back on itself, and fixed to an anchor point (which can be another fastener).  The Knight Group are a specialist manufacturer of wire and cable and typically supply safety lock wire on ½ or 1 kg spools, in handy ½ kg plastic tubs, or in coil.

Our locking wire materials are available in a range of sizes on 1/2 or 1kg weights.  Non standard sizes are available by request.  All Locking and safety wire can be supplied on spools, coils or colour coded containers to allow for ease of identification and material protection.  Wire uncoils from the centre of the container to avoid becoming tangled when in use. 

Safety Lock Wire: simple, effective failsafe technology

Safety across a range of industries is of paramount importance, and there are a number of failsafe technologies that add additional layers of security.

Particularly within the aerospace, marine, automotive and industrial sectors where wear and tear, vibration and corrosion can cause failures, the use of Safety Lock Wire can prevent fasteners from shaking loose or falling out.

Safety lock wire can also act as a visual indicator that fasteners have been properly checked and tightened.

Annealed Locking Wire

Locking wire (safety lock wire) is a soft annealed wire used to secure nuts, bolts and components which are subject to vibration and/or a critical environment.

The wire, made of malleable stainless steel alloy, is passed through small holes on the fastener, looped back on itself and fixed to an anchor point (which can be another fastener).

Twisting the Safety Lock Wire creates tension on this fixed loop which prevents the fasteners from shaking loose and falling out.

Tips on using Safety Lock Wire correctly

Before applying the safety wiring, you should first tighten the nut or bolt to its correct tension. If possible, align the holes through which the safety wire will be passed, however do not align these at the expense of tensioning the fasteners incorrectly.

Safety Lock Wire should always be installed so that the fastener tightens itself. In other words, the safety wiring should pull the head of the nut or bolt in a tightening direction once secured to the anchor point.

Don’t overstress the safety wiring by overwinding it – this could cause it to fail, rendering it useless as a failsafe technology.
Once the safety wire has been installed, you should always clip ends off at least 4 to 6 turns after the loop.

Ensure you get the highest quality Safety Lock Wire for the correct application.

We supply the wire on ½ or 1 kg spools, in handy ½ kg plastic tubs, or in coil. Standard sizes are available from stock, and non-standard sizes are produced on request.

Aerospace locking wire, also known as safety lock wire, is a soft annealed wire used to secure nuts, bolts, and components in aerospace, marine, automotive, and industrial sectors. It prevents fasteners from shaking loose or falling out due to wear and tear, vibration, and corrosion. The wire is made of malleable stainless steel or nickel alloy, passed through small holes on the fastener, looped back on itself, and fixed to an anchor point (which can be another fastener). Twisting the safety lock wire creates tension on this fixed loop, preventing the fasteners from shaking loose and falling out.

Aerospace locking wire is primarily made from: 

  • Stainless Steel alloys: 304 (1.4301), 316 (1.4401 / 1.4436 ), 321 (1.4541) 
  • Nickel alloys: Monel (Alloy 400), Inconel (Alloy 600) 
  • Copper

High-quality aerospace locking wire should be:

  • Made from durable and corrosion-resistant materials
  • Flexible and malleable for easy installation
  • Able to withstand high levels of vibration and wear
  • Compliant with international specifications and standards

To choose the right size and material for your aerospace locking wire, you will need to consider the specific application and the environment in which it will be used. Another key consideration is the level of corrosion resistance required. If you have further questions, contact our knowledgeable team for locking wire recommendations based on your needs.

To install aerospace locking wire:

  1. Tighten the nut or bolt to its correct tension.
  2. Align the holes through which the safety wire will be passed without compromising the tensioning of the fasteners.
  3. Install the safety lock wire so that the fastener tightens itself, pulling the head of the nut or bolt in a tightening direction once secured to the anchor point.
  4. Do not overstress the safety wiring by overwinding it, as this could cause it to fail.
  5. Clip ends off at least 4 to 6 turns after the loop.
  6. To remove aerospace locking wire, simply cut the wire and unwind it from the fasteners.

Aerospace locking wire is also known as safety lock wire and is commonly used in aerospace, marine, automotive, and industrial sectors to secure nuts, bolts, and components.

Regularly inspect the aerospace locking wire for signs of wear, corrosion, or damage. Replace the wire as needed to ensure the continued safety and reliability of the secured components.

Aerospace locking wire is typically supplied on ½ or 1 kg spools, in handy ½ kg plastic tubs, or in coil. Store the wire in a dry, cool, well-ventilated area to prevent corrosion. When transporting, ensure the wire is secured correctly to avoid damage.
