S-93595A546 5/16"-18 x 1 1/2" ASTM B456 18-8 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with Chrome Plated 18-8 Stainless Steel construction for extended service life in harsh environments
• High tensile strength of 70,000 PSI ensures reliable performance under heavy loads and vibration
• Precise Class 3A thread fit provides secure fastening with minimal play in critical assemblies
• Rockwell B70 hardness rating maintains thread integrity and prevents stripping during repeated installations
• Standard hex socket drive allows for high torque application with common 1/4" tools
• Full threading along 1-1/2" length enables adjustable positioning and maximum grip depth
• Compliance with major industry standards including ASTM B456 for consistent quality assurance

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these socket head cap screws combine the corrosion resistance of 18-8 stainless steel with the enhanced surface protection of chrome plating. The 5/16"-18 UNC coarse threads with Class 3A fit provide exceptional engagement in both metals and plastics, reducing the risk of cross-threading during high-volume assembly. The hex drive socket design ensures maximum torque transfer without cam-out, while the fully threaded configuration offers versatile clamping force distribution. Ideal for machinery, automotive components, and structural frameworks where 70,000 PSI tensile strength and consistent performance under dynamic loads are critical requirements.

Specification Summary & Compliance

This socket head cap screw features precision UNC coarse threads with Class 3A fit tolerance for secure fastening applications. Manufactured in compliance with ASTM B456 specifications for plating quality and dimensional accuracy. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety standards for industrial use.
