How to make a 2 bolt safety wire?
How to create nice and tight safety wire in a 2-bolt pattern. Pay close attention to the final “barrel-roll” technique at end of both twist steps. Watch the operator lock the tighness into the first twist after second bolt is penetrated.
How are nuts, bolts and screws wired together?
Figure 1 illustrates various methods commonly used in Safety Wiring nuts, bolts and screws. Observing this illustration, it will be noted that: A. Examples 1, 2 and 5 show the proper method of Safety Wiring bolts, screws, square-head plugs and similar parts when wired in pairs.
How is the termination of a safety wire twisted?
N.B. Wire is always twisted clockwise and termination is bent back on itself to minimize occurrence of punctured fingers. Note that fastener loosening is resisted by twisted portion of safety wire. Tools for wiring depend on the mechanic’s preference.

What’s the correct size of wire for a bolt?
When done, cut and twist the loose end with a pair of diagonal cutters or the safety wire cutters to prevent cutting fingers. Thanks for submitting a tip for review! Use the preferred sizes 0.020, 0.025, 0.032 of wire depending on the size of the hole in bolt. The smaller sizes are used for smaller holes. The wire diameter used is 0.020, or 0.025.

What are the dimensions of McMaster safety wire bolts?
Material meets SAE J429 specifications for quality. Dimensions meet ASME B18.2. 1 specifications. Grade 5 steel hex head screws are marked with three radial lines. Length is measured from under the head. Black-oxide steel screws are mildly corrosion resistant in dry environments. Zinc-plated steel screws resist corrosion in wet environments.
