Review: Good quality safety lock wire - I'm using it on my sailboat shackles - Nice stiff safety lock wire. I live on a sailboat and have many shackles and other hardware that require safety lock wire. I have found this product to be strong, very stiff (a good thing), and easy to use. The dispenser is well thought out and has a couple of spots to fold the wire to keep it from dropping back into the dispenser. I love that I can pick it up, grab a wire tool, snip off a section, fold the end and get to securing my hardware. Works perfectly. I don't anticipate any issues with the quality of the stainless steel. Since I'm in an ocean environment I will know quickly. I'll update this review if there are any issues. I am confident enough with this product that I put it on my most critical shackle - the anchor shackle. Review: Great wire. They also have different thicknesses works great for my applications. - The durability is high, this size works perfect for my needs, the use possibilities are endless, being stainless steel is rust resistant, bendability is great, I use it quite often, a great value for the money , easy to use …. ## Features - SPECIFICATION & COMPLIANCE AUTHORITY: NASM20995C / MS20995C compliant stainless steel safety lock wire manufactured from T302/304 alloy and meeting ASTM A580 Condition A and AMS5697 standards for regulated aviation and industrial use. - PROFESSIONAL GAUGE & DIAMETER RANGE: Available in multiple diameters from .020 to .063, including high-demand .032 safety wire, providing correct gauge strength with aviation-grade standards and trusted performance technicians may use for aircraft, automotive, motorsport, and industrial fasteners. - CORROSION-RESISTANT STAINLESS STEEL: T302/304 stainless steel twisted metal safety wire resists rust and oxidation in humid, marine, outdoor, and high temperature exposed settings.
