Hex Head (Inch)

Standard hex head bolts, also known as hex head cap screws, are versatile fasteners commonly used in a wide range of construction and assembly projects. Featuring a hexagonal head, these bolts are designed for applications where high tensile strength and durability are required. Fasteners Direct offers a variety of standard hex head bolts in different grades, materials, and finishes, including zinc plating, stainless steel, and silicon bronze.

Features and Benefits

A standard hex head bolt comes in a range of hex bolt dimensions, making them suitable for various applications. The hex head design provides an easy grip for tightening with a wrench or socket, while the washer face under the head ensures a stable bearing surface. These bolts are available in different thread types and directions to accommodate specific needs.

Material Options

• Stainless Steel Hex Bolts: Stainless steel hex bolts offer excellent corrosion resistance, making them ideal for use in marine environments and other harsh conditions. They provide long-lasting performance, even in applications exposed to moisture and rust.
• Zinc Plated and Yellow Zinc Bolts: Zinc-plated and yellow zinc-coated hex bolts provide a layer of protection against corrosion. The thick coating helps prevent rust and extends the life of the fastener, making them suitable for general construction and outdoor use.
• Medium Carbon Steel and Heat Treated Bolts: Medium carbon steel hex head bolts, including heat-treated Grade 5 and Grade 8 options, offer higher tensile strength for demanding applications. These bolts are perfect for structural and heavy-duty projects requiring additional strength and durability.
• Silicon Bronze and Brass: Silicon bronze and brass hex bolts are ideal for decorative or specialized applications where corrosion resistance and a non-magnetic property are required.

Applications

Standard hex head bolts are used for a variety of purposes, including fastening construction materials, securing components in harsh environments, and providing reliable connections in structural projects. The hexagonal head design allows for easy installation and removal, making them a go-to fastener for construction and repair tasks.

• Construction Materials: Hex head bolts are often used to secure steel, wood, and other construction materials, providing a strong and stable connection.
• Harsh Environments: Stainless steel and zinc-plated hex bolts are designed to resist corrosion, making them suitable for outdoor use and marine environments.
• Higher Tensile Strength: Grade 5 and Grade 8 hex head bolts are heat-treated to provide increased tensile strength, making them ideal for heavy-duty and structural applications.

Standard Hex Head Bolt FAQs

What are standard hex head bolts used for?

Standard hex head bolts are used to secure materials in construction, assembly, and repair projects. They are commonly used in structural applications where high tensile strength and durability are required.

What materials are available for standard hex head bolts?

Standard hex head bolts are available in stainless steel, medium carbon steel, silicon bronze, and brass. Stainless steel and zinc-plated options provide excellent corrosion resistance, while medium carbon steel offers higher tensile strength for heavy-duty applications.

What are hex cap screws and how do they differ from hex head bolts?

A hex cap screw is similar to a hex head bolt but features tighter tolerances and a flat washer face under the head, providing a more precise fit. They are often used in applications requiring more exact fastening and are commonly found in machinery and automotive projects.

What is the difference between Grade 5 and Grade 8 hex head bolts?

Grade 5 hex head bolts are medium-strength bolts suitable for most construction projects, while Grade 8 bolts are heat-treated to provide a higher tensile strength, making them ideal for heavy-duty and load-bearing applications.

Why is corrosion resistance important for hex head bolts?

Corrosion resistance is crucial for hex head bolts used in outdoor or harsh environments. Materials like stainless steel and zinc plating help prevent rust and extend the life of the fastener, ensuring reliability in challenging conditions.

How do I choose the right hex head bolt for my project?

Choosing the right hex head bolt depends on the materials being fastened, the required tensile strength, and the environmental conditions. Fasteners Direct offers a range of hex bolts in various grades and finishes, making it easy to find the perfect fit for your needs.
