[6 PKG] Hex Head Cap Screws Grade 5 Steel Plain 1-1/2-6 x 8

Hex Head Cap Screws Grade 5 Steel Plain 1-1/2-6 x 8 are engineered fasteners designed for heavy-duty assemblies requiring high strength and reliability. With a plain, uncoated steel finish, these screws deliver dependable performance in a wide range of industrial and mechanical applications.

Key features

• Material: Grade 5 steel — a strong, quenched and tempered alloy designed for reliable performance under load.
• Finish: Plain steel with no coating, suitable for painting or plating processes; note that it is less resistant to corrosion than coated variants.
• Size: 1-1/2" nominal diameter, 6 threads per inch (6 TPI), with an overall length of 8 inches.
• Head design: Hex head for easy driving with common wrenches or sockets, providing a large bearing surface for higher torque.
• Thread type: Coarse thread (6 TPI) for faster assembly and strong engagement in tapped holes or pre-drilled surfaces.

These fasteners are ideal for machinery, equipment, and heavy-duty assemblies where high-strength, uncoated fasteners are preferred. They are well-suited for use in shop, industrial, and construction settings where reliable clamping and secure joints are critical.

Note: Plain steel is susceptible to corrosion when exposed to moisture. For outdoor or humid environments, consider protective coatings or plating to enhance longevity.
