Use these general purpose 18-8 stainless steel screws for a variety of fastening applications. They have good chemical resistance.

18-8 stainless steel button head screws have good chemical resistance and may be mildly magnetic.

Brass button head screws are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.

Choose these screws for their adherence to strict military standards for material and construction.

More corrosion resistant than 18-8 stainless steel screws, these screws have excellent resistance to chemicals and salt water. They may be mildly magnetic.

Made from alloy steel, these inch size set screws have a thin edge that digs into hard surfaces for a secure hold.

Made from black-oxide alloy steel, these set screws resist corrosion in dry environments. They dig into hard surfaces for a secure hold and have serrations on the cup edge that grip the material surface to resist loosening.

These alloy steel set screws have a pointed tip that wedges into the contact surface for a secure hold on soft materials such as brass.

These nuts have good chemical resistance and may be mildly magnetic.

Made from nylon 6/6, these nuts resist oil, grease, and solvents (except mineral acids).

These locknuts have good chemical resistance.

About half the strength of medium-strength steel cap nuts, use them in light duty fastening applications, such as securing access panels.

A distorted thread grips the screw to resist loosening.

Change inch threads to metric with these adapters, or swap metric threads for inch. An external hex lets you tighten or loosen them with a wrench.

Adapt threaded rods from inch to metric. These adapters connect two male-threaded fasteners, so you can change the gender of a mating part or increase or decrease its thread size. The hex-shaped body fits into the head of a standard wrench.

One side inch, one side metric, and a hex in the middle—these handy fasteners connect two female-threaded parts, such as coupling nuts, adapting from inch threads to metric. Tighten with a standard wrench.
