Fractional Sizes 316 Stainless Steel Flat Socket Head

Fractional Sizes 316 Stainless Steel Flat Socket Head Cap Screw

Fractional Sizes 316 Stainless Steel Flat Socket Head Cap Screws are premium corrosion-resistant fasteners engineered for strength, durability, and a flush, finished appearance. Manufactured from marine-grade 316 stainless steel, these flat head socket cap screws provide exceptional protection against harsh environments, including saltwater exposure, chemicals, and high-humidity conditions.

Designed with a countersunk flat head and internal hex drive, these screws sit flush with the surface once installed, making them ideal for applications requiring smooth finishes, reduced snag points, and clean aesthetics.

Key Features of 316 Stainless Steel Flat Socket Head Cap Screws

Marine-Grade Corrosion Resistance

316 stainless steel contains added molybdenum, significantly improving resistance to chlorides, salt spray, and chemical exposure. This makes fractional 316 flat socket head cap screws the preferred choice for marine equipment, coastal construction, food processing facilities, and chemical plants.

Flush Countersunk Head Design

The flat head (82° countersink) allows the screw to sit level with the material surface, improving appearance and safety. This design is especially beneficial in equipment panels, decking, enclosures, and fabricated assemblies where protruding hardware is not acceptable.

High-Strength Internal Hex Drive

The precision-machined socket drive enables higher torque application compared to slotted or Phillips drives. This provides secure fastening while minimizing cam-out and installation damage.

Available Fractional Sizes & Specifications

Fractional sizes commonly range from #10, 1/4", 5/16", 3/8", to 1/2" diameters, with various lengths available to meet specific clamping requirements. Thread options typically include UNC (coarse) and UNF (fine) threads for versatile application compatibility.

Common Applications

316 stainless steel flat socket head cap screws are widely used in:

• Marine hardware and boat building

• Dock and pier construction

• Food and beverage processing equipment

• Pharmaceutical manufacturing

• Outdoor architectural projects

• Chemical processing systems

Why Choose 316 Stainless Steel?

When maximum corrosion resistance is critical, fractional size 316 stainless steel flat socket head cap screws deliver unmatched longevity, strength, and performance. Their flush profile and superior environmental protection make them the ideal fastening solution for the most demanding applications.
