Material Options

Choose low head socket cap screws built from trusted materials built to perform in demanding applications. Each offers distinct advantages depending on your environment and load requirements.

Alloy Steel

A durable and high-strength option ideal for mechanical, structural, and industrial applications. With excellent tensile strength and wear resistance, alloy steel socket screws hold up under repeated torque and stress in harsh working conditions.

Stainless Steel 18-8 (304)

Corrosion-resistant and versatile. Great for general environments and equipment. This grade provides a clean appearance and solid protection against rust in most indoor and mildly corrosive settings.

Stainless Steel 316

Premium corrosion resistance for marine, medical, and chemical environments. With added molybdenum, 316 stainless excels in saltwater, chlorine, and acidic atmospheres where standard 304 can’t hold up.

Stainless Steel 8-2

Excellent resistance in harsh environments, combining strength and longevity. Known for superior mechanical properties and corrosion protection, stainless 8-2 performs well in industrial, marine, and chemical environments.

Available Finishes

Each finish provides a unique balance of corrosion protection, appearance, and surface hardness. We’ll help you choose what works best for your application. Finishes available for low head socket cap screws include:

Black Oxide

A dark, low-sheen coating that adds mild corrosion resistance while enhancing the fastener’s surface hardness. Best suited for dry, indoor environments where aesthetics and minimal glare matter.

Thermal Black Oxide

Applied with heat treatment for deeper penetration and better wear resistance than standard black oxide. Ideal for moderate-duty machinery, industrial assemblies, and tooling.

Mechanical Zinc Cr+3

A uniform, silver-gray coating applied without electricity. Offers reliable rust protection without the risk of hydrogen embrittlement. Commonly used in electrical and structural applications.

Zinc Bake Cr+3

An electroplated zinc layer followed by baking to relieve hydrogen embrittlement. This finish offers strong corrosion resistance and a clean, bright appearance. Especially effective for high-strength alloy steel screws used in mechanical and structural work.
