Material Options

South Coast Fasteners stocks Grade 5 hex cap screws in medium carbon steel that has been heat treated for added strength and durability. These screws are engineered for structural applications that require more holding power than Grade 2 but don’t need the extreme tensile strength of Grade 8. Commonly used in automotive assemblies, agricultural machinery, and construction projects, Grade 5 offers a dependable balance between performance and cost.

Medium Carbon Steel

This material provides enhanced strength and reliability through controlled heat treatment processes. It’s an ideal choice for mid-strength mechanical and structural fastening applications where consistent torque, vibration resistance, and moderate tensile load are essential. Frequently selected for bolting engines, gear housings, and other general assemblies.

Available Finishes

To meet varying environmental and operational needs, South Coast Fasteners offers Grade 5 hex cap screws in the following finishes:

Plain

Uncoated steel for dry, controlled environments or internal use where corrosion is not a primary concern. Offers ease of inspection and clean metal-to-metal contact in enclosed applications.

Yellow Zinc Cr+6

A bright, golden trivalent finish that combines aesthetic appeal with excellent corrosion protection. Popular in automotive, hardware, and construction jobs where visibility and light weather resistance are desired.

Zinc Cr+3

A trivalent zinc plating with a silver-blue appearance, providing moderate corrosion resistance and a clean, uniform finish. Commonly used in general mechanical applications where parts are visible or partially exposed.

Zinc JS500

This high-performance finish provides superior corrosion protection through a layered coating system. JS500 is commonly chosen for outdoor or industrial environments where hex cap screws are exposed to moisture, chemicals, or salt. It also offers enhanced resistance to hydrogen embrittlement in high-strength fasteners.
