This high-quality screw is constructed from medium carbon alloy steel and is heat-treated to achieve a hardness level of HRC 33-39, making it one of the strongest and most resilient fasteners available.

Specifications:

• Material: Medium Carbon Alloy Steel
• Hardness: HRC 33-39
• Thread Size: ANSI B1.1, Class 2A
• Tensile Strength: Minimum 150,000 psi
• Proof Load: Minimum 120,000 psi
• Yield Strength: Minimum 130,000 psi
• Finish: Black Oxide or Yellow Zinc Plated (to prevent corrosion)

The Grade 8 Hexagonal Caps Screw features a hexagonal head, commonly referred to as a “hex head,” designed for easy tightening and removal with a standard wrench or socket. This type of head provides a larger contact area, ensuring greater torque application without causing damage to the screw or the surrounding components.

The primary purpose of the Grade 8 Hexagonal Caps Screw is to provide superior holding power and resistance to mechanical stresses, particularly in applications where vibrations, shocks, and heavy loads are common. These screws excel in demanding environments such as construction, automotive, machinery, and aerospace industries.

Key Features and Benefits:

1. High Strength: The Grade 8 designation indicates that these screws have a minimum tensile strength of 150,000 psi, offering exceptional resistance to deformation and breakage even under extreme loads.
2. Reliability: The screws undergo rigorous testing and quality control to ensure consistent performance, making them a trusted choice for critical applications.
3. Vibration Resistance: The Grade 8 material and heat treatment contribute to improved resistance against loosening due to vibrations.
4. Corrosion Resistance: The black oxide or yellow zinc plating provides a protective barrier against corrosion and environmental elements.
5. Versatility: The screws are available in various lengths, thread sizes, and head styles, making them suitable for diverse applications.
6. Easy Installation: The hex head design allows for quick and straightforward tightening, saving time and effort during assembly.
7. Longevity: The Grade 8 Hexagonal Caps Screw is engineered to withstand harsh conditions and extended use, ensuring long-lasting performance.
