Understanding Hex Head Screws

What are Hex Head Screws?

Hex head screws, also known as hex bolts or cap screws, are fasteners with a hexagonal head designed to be tightened or loosened using a wrench. Their hexagonal shape provides a superior grip compared to other screw head types, allowing for greater torque and less risk of stripping the head. They are widely used in various applications due to their strength and reliability.

Types of Hex Head Screws

Several variations exist within the hex head screw family. Key distinctions include:

• Fully Threaded: Threads extend the entire length of the screw.
• Partially Threaded: Threads only cover a portion of the screw shaft, often preferred when a large bearing surface is needed.
• Shoulder Screws: Feature a shoulder under the head, useful for precise positioning.

Materials and Grades

The material composition of a hex head screw significantly impacts its strength, corrosion resistance, and overall lifespan. Common materials include:

• Steel: A widely used material offering high strength. Various grades exist, with higher grades indicating increased tensile strength. For example, Grade 8 steel is significantly stronger than Grade 5 steel.
• Stainless Steel: Offers superior corrosion resistance, ideal for outdoor or damp environments. Common grades include 304 and 316 stainless steel.
• Brass: Offers good corrosion resistance and is often used in applications requiring non-magnetic properties.
• Aluminum: Lightweight and corrosion-resistant, frequently used in aerospace and automotive applications.

Choosing the Right Size and Application

Selecting the correct size hex head screw is crucial for proper installation and performance. Size is typically specified by diameter and length. Diameter is measured in inches or millimeters, while length is the overall length of the screw, including the head.

The application will also influence your choice. Consider the material being fastened, the required strength, and the environmental conditions. For high-strength applications, stronger materials and higher grade screws are necessary. For corrosive environments, stainless steel or other corrosion-resistant materials are preferable.

Where to Buy High-Quality Hex Head Screws

When sourcing hex head screws, prioritize quality and reliability. Reputable suppliers offer a wide selection of materials, sizes, and grades to meet your specific needs. Consider suppliers with established reputations and positive customer reviews.
