Steel hex bolts come in different strength "grades." They're graded according to the American Society for Testing and Materials and the Society of Automotive Engineers. Higher grades have greater tensile strength. The lowest strength fastener is ASTM Grade A307, while the highest strength fastener is SAE Grade 8.
Stainless Steel Hex Bolts
Stainless steel Hex Bolts are an excellent choice for a wide range of applications. They are popular in DIY projects and guardrails. Their high tensile strength makes them ideal for applications requiring corrosion resistance. Aside from their strength, stainless steel bolts are also recyclable and are environmental-friendly. Listed below are some of the benefits of stainless-steel hex bolts. These bolts are available in a variety of sizes, strength grades, and materials.
The diameter of a hex bolt is the outside diameter of the threads. A large diameter means that it is too long, so it is not recommended for applications where the bolt must be fully threaded. To determine the correct length of a bolt, measure it from under the head to the end of the bolt. When ordering, ensure that the length is consistent with the diameter of the bolt's head. Stainless steel hex bolts are available in different lengths to suit the needs of different applications.
Silicon Bronze Hex Bolts
Silicon bronze hex bolts are highly corrosion-resistant fasteners made from an alloy of copper and low-lead brass. Their outstanding mechanical properties and excellent surface finishes make them desirable for marine and industrial applications. Silicon bronze fasteners are non-sparking and feature excellent corrosion resistance. They can be found in a wood case or pallet. You can choose from two different sizes for different applications. Here are some of the common sizes:
Silicon Bronze Hex Cap Screws were developed for the chemical industry. They are corrosion-resistant in a variety of liquids and exhibit excellent hot workability. Silicon Bronze Machine Screws are widely used in marine and pole line hardware. Silicon Bronze Countersunk Slotted Screws are widely used in welded tanks and unfired pressure vessels. They feature good hardness and casting properties and are easy to weld. Silicon bronze Allen Cap Screws are ideal for a variety of applications, from industrial to marine.
Hex Bolts for Sheet Metal
Hex bolts for sheet metal are also called self-tapping screws. They are highly versatile and come in a variety of materials. Some types of hex bolts have a flat head and are countersunk into the material. Others are slightly rounded and have a hex washer head. These screws are typically used for fastening sheet metal to a variety of surfaces. Whether you're working with thin sheet metal or thick sheet metal, you'll be pleased with the quality of these bolts.
Another popular type of fastener is the sheet metal screw. They have a flat or round head and are usually thread-cutting. Their threads are also sharp, making them effective for fastening different materials. The diameter, thread count, and length of these screws are typically indicated by a series of numbers. Some types of sheet metal screws are referred to as self-tapping screws, although there are also hex nuts.
Sheet Metal Screws
Hex bolts for sheet metal screws are gaining in popularity for a variety of applications. Generally, hex screws have a flat or round head, and are thread-cutting by design. They fit into pre-drilled holes without the need for pre-drilling. Hex bolts for sheet metal screws come in three main types: coarse, hex, and flat. Type A sheet metal screws have a coarse thread, type B has a fine thread, and type AB combines both coarse and fine threads in one.
Carbon steel screws are the most common and economical type of sheet metal screws. However, they are susceptible to rusting when exposed to moisture and chemicals. For these reasons, they are typically used indoors. Stainless steel and galvanized screws are available, but they are often more expensive than standard steel screws. Some hex bolts and sheet metal screws come with special coatings such as zinc or nickel to change their appearance.
Hex-Head Wood Screws
If you're building something out of wood, you'll need hex-head wood screws. These screws are commonly known as hex bolts, but they also go by other names, including hex cap screws. In many cases, you can use the same type of screws with hex bolts if you don't need to tighten the screw after installation. Here are some examples.
Hex-head screws are typically used for interior construction projects. They have hexagon-shaped heads and are fully threaded from one end to the other. They are available in steel and galvanized materials. Whether you're doing interior work or outdoor work, these screws are a great choice. They are a great choice for tight spaces because they are easy to clean and shine. But before you get started, you'll need to make sure you know what kind of project you'll be doing before you buy hex-head screws.
