316 Stainless Steel Socket Head Cap Screws – Superior Strength in Corrosive Environments

316 stainless steel socket head cap screws are high-performance fasteners designed for demanding industrial, marine, and chemical applications. Featuring a cylindrical head with an internal hex drive, these precision fasteners provide exceptional clamping force while allowing installation in tight or counterbored spaces. When corrosion resistance and strength are critical, 316 stainless socket head cap screws are a top-tier solution.

Enhanced Corrosion Resistance with 316 Stainless Steel

316 stainless steel, also known as A4 stainless, contains molybdenum for improved resistance to chlorides, saltwater, and harsh chemicals. Compared to 18-8 or 304 stainless steel, 316 offers superior protection against pitting and crevice corrosion, making it ideal for coastal, marine, and washdown environments.

Key material benefits include:

• Outstanding resistance to saltwater and de-icing chemicals

• Excellent performance in acidic and high-humidity settings

• Non-rusting, long-lasting finish

• Reliable strength at elevated temperatures

Precision Engineering and Mechanical Properties

Socket Head (Allen Drive) Design

The internal hex socket drive allows for higher torque application than traditional slotted or Phillips fasteners. This design reduces cam-out, improves tool engagement, and delivers greater clamping force. The tall cylindrical head provides a larger bearing surface and enhanced tensile strength in compact assemblies.

Common Specifications

• Material: 316 (A4) stainless steel

• Drive Type: Internal hex socket

• Thread Style: UNC (coarse) and UNF (fine)

• Sizes: #0 through 1” diameter (fractional sizes available)

• Finish: Plain stainless (natural corrosion-resistant finish)

These screws are commonly manufactured to ASTM F593 and ASME dimensional standards for industrial consistency.
