Malin MS20995C Stainless Steel Safety Wire Lockwire, 0.025 Inch Diameter, Canister, Military Specification 304 Stainless for General Aviation Fastener Safety Wiring
The 0.025 inch diameter is the most commonly specified safety wire size for general aviation fastener applications, from oil system fittings and drain plugs to control hardware and access panel fasteners, because it provides the right combination of tensile strength and workability for the range of fastener sizes and wire hole configurations encountered in everyday maintenance. Supplied by JHEARs Aerospace, Malin MS20995C at 0.025 inch diameter is manufactured from 304 stainless steel to military specification, delivering the tensile strength and flexibility that aviation lockwire work requires. It twists smoothly and consistently under the pliers without snapping or kinking mid-twist, which is the practical performance characteristic that separates quality mil-spec wire from generic alternatives that look the same but behave differently when being worked.
The canister format dispenses wire cleanly and tangle-free throughout the entire reel, keeping the wire manageable on the bench and at the aircraft without the frustration of tangles and kinks that waste wire and slow the job down. For MRO environments where safety wiring is a routine daily task and for private hangar owners maintaining their own aircraft to the correct standard, Malin MS20995C in the canister format at 0.025 inch is the correct, mil-spec wire to have on the shelf.
Spec: Malin MS20995C stainless steel safety wire lockwire, 0.025 inch diameter, 304 stainless steel, military specification. Canister format for tangle-free dispensing. Suitable for general aviation oil system fittings, drain plugs, control hardware, and fastener safety wiring applications where 0.025 inch diameter lockwire is specified.
Who this is for: Aircraft mechanics and A and P technicians performing routine safety wiring on oil systems, drain plugs, and control hardware across GA aircraft types, MRO engineers requiring mil-spec 0.025 inch stainless lockwire for compliance with maintenance manual safety wiring requirements, and private aircraft owners maintaining their own aircraft to the correct documented standard.
FAQ
Why is 0.025 inch the most commonly used safety wire diameter in general aviation?
The 0.025 inch diameter provides a balance of tensile strength sufficient for most GA fastener safety wiring requirements and workability that allows clean twisting without the wire becoming too stiff or brittle during the wiring process. Larger diameters such as 0.032 inch are specified for heavier fastener applications, while 0.020 inch is used for smaller or lighter-duty applications. The correct diameter for each specific application is determined by the aircraft maintenance manual.
How much wire is in the canister and is it sufficient for a full annual inspection?
Canister quantities vary by product variant. The canister format is designed to provide a substantial working quantity for extended maintenance use. For a full annual inspection involving significant safety wiring work, having a full canister on hand at the start of the inspection ensures the job is not interrupted by running out of wire mid-task.
Can this wire be used with both manual and automatic safety wire twisting pliers?
Yes. Malin MS20995C 0.025 inch wire is compatible with both manual safety wire twisting pliers and automatic/ratchet-type wire twisters. The consistency and workability of the mil-spec wire ensures reliable performance with both tool types throughout the twisting process.
Why should I purchase my safety wire from JHEARs Aerospace?
At JHEARs Aerospace, we supply mil-spec aviation safety wire and lockwire products sourced to ensure specification compliance and material authenticity. Our range gives mechanics and MRO operations confidence that the wire they are installing meets the documented requirements for the critical fasteners and components it is securing.
