hexagon screw

This comprehensive guide explores the world of hexagon screws, covering their types, applications, and selection criteria. We'll delve into the specifics of different materials, sizes, and head styles to help you choose the perfect screw for your project. Learn how to identify the right hexagon screw for your needs and avoid common mistakes.

What is a Hexagon Screw?

A hexagon screw, also known as a hex bolt or hex head bolt, is a type of fastener characterized by its hexagonal head. This head shape allows for easy tightening and loosening using a wrench or socket. The design provides a strong grip and prevents the fastener from stripping or damaging under pressure. The strength and versatility of hexagon screws make them incredibly common in a wide range of applications.

Types of Hexagon Screws

Material

Hexagon screws are manufactured from various materials, each offering different properties:

• Steel: The most common material due to its strength, durability, and cost-effectiveness. Various grades of steel offer different levels of strength and corrosion resistance. Look for information like Grade 5 or Grade 8 which indicate increased tensile strength.
• Stainless Steel: Offers superior corrosion resistance, making it ideal for outdoor or wet environments. Different grades of stainless steel (e.g., 304, 316) have varying corrosion resistance levels.
• Brass: Provides good corrosion resistance and is often used in applications where electrical conductivity is important. It’s generally softer than steel.
• Aluminum: A lightweight option, often preferred for applications where weight reduction is critical.

Head Styles

Hexagon screws come in various head styles, each suited for different applications:

• Standard Hex Head: The most common type, with a standard-sized hexagon head.
• Flanged Hex Head: Features a flange under the head, providing a larger bearing surface and preventing damage to the material being fastened.
• Button Head Hex Screw: A lower-profile head, ideal for applications where a low-profile fastener is required.

Thread Types

The thread type significantly impacts the screw's holding power and application:

• Coarse Thread: Offers quick installation and a strong grip in softer materials.
• Fine Thread: Provides finer adjustments and increased strength in harder materials. Also useful in applications where there's limited depth for the screw.

Selecting the Right Hexagon Screw

Choosing the right hexagon screw depends on several factors:

• Material being fastened: The material's strength and hardness will influence the type of screw and its thread type.
• Application environment: Will the screw be exposed to the elements? Consider corrosion resistance if needed.
• Load requirements: Determine the anticipated load and select a screw with sufficient strength.
• Accessibility: Consider the available space and choose a screw head style and size that allows easy access for tightening.

Hexagon Screw Sizes and Standards

Hexagon screws are available in a wide range of sizes, typically defined by their diameter and length. These sizes adhere to industry standards like ISO and ANSI. You can find detailed size charts on manufacturers' websites or engineering handbooks. Always refer to these standards when ordering or specifying hexagon screws.
