LEAD FREE - Solder that contains no lead (meets up and coming industry standrds).

LEXAN(R) (PC) (PLASTICS) - Polycarbonate exhibits the highest impact strength ove a range of temperatures from -60F to 270F. It is fine for all precision parts, or where transparency is desired. Its water-clear transmittance (89%) makes it excellent for visors or guards. It shows good creep resistance and has a temperature-independent dielecric constant, as well as good insulating properies.

LIGHT TORQUE - 1/3 of initial installation value i.e. MIL spec.

LOCK - Designed to secure fasteners that have a tendency to rotate or lose friction. Often paired with a flat washer to evenly disburse load without deforming the assembly. See Lock Washers and Lock Nuts
