The Ultimate Guide To Brass Socket Head Cap Screws: Metric Edition

Brass socket head cap screws are a type of fastener typically used in machine parts, die fixturing, and clamping. They are often referred to as Allen head screws and are known to provide increased resistance to cam-out due to their hexagonal recess. Brass socket head cap screws are available in various sizes and can be purchased from suppliers such as Mutual Screw & Supply, MF Supply, and Fastenright Ltd. These screws are manufactured from solid brass, providing good corrosion resistance, water resistance, and a decorative finish, making them ideal for outdoor use and in some coastal environments.

Brass Hexagon Socket Cap Screws

One of the advantages of Brass Hexagon Socket Cap Screws is their increased resistance to cam-out due to their hexagonal recess. This provides greater efficiency compared to fasteners with a standard Phillips or slotted drive. Additionally, these screws are manufactured from solid brass, which offers good corrosion resistance, water resistance, and a decorative finish. As a result, they are well-suited for outdoor use and in some coastal environments.

When choosing Brass Hexagon Socket Cap Screws, it is important to consider the dimensions and specifications that meet the relevant standards, such as DIN, ISO, or JIS for metric screws, and ASME for US/Imperial screws. These screws are commonly used in machine parts, die fixturing, and clamping applications.

Brass Hex Head Cap Screws

The most common specifications for hex screw specifications include ASTM A449 and SAE J429 Grade-2, Grade-5, and Grade-8. Grade-2 screws are made from low or medium carbon steel and are suitable for non-critical applications without extreme temperatures or stress. Grade-5 screws are made from heat-treated medium carbon steel and offer greater tensile strength. Grade-8 screws are also made from heat-treated medium carbon steel and are designed for high-stress applications.

When it comes to dimensions and standards, metric brass hex head cap screws follow the DIN, ISO, or JIS standards. On the other hand, US/Imperial brass hex head cap screws adhere to the ASME B18.2.1 and B18.3 specifications.

Metric Socket Head Cap Screws

When choosing the right type of metric socket head cap screw for your project, consider the environment in which the screws will be used. For moderate corrosion resistance, zinc-plated alloy steel is a good option. If your project involves saltwater or chlorine environments, stainless steel metric cap screws are recommended. For a matte black finish and mild corrosion resistance, consider using a class 12.9 alloy steel with a black oxide finish.

When purchasing metric socket head cap screws, you can choose from various grades and sizes to suit your specific requirements. For example, the most common grade of stainless steel for general use is 18-8 (A-2), while 316 (A-4) stainless steel offers high corrosion resistance and is ideal for saltwater and chlorine environments.

In addition to the type of screw, you can also find a variety of kits and assortments that include both screws and other hardware, such as nuts and bolts. These kits can be useful if you need a range of sizes or types of screws for your project.

Overall, metric socket head cap screws offer a versatile and durable fastening solution for a wide range of applications.

Brass Hexagon Head Bolts

Hex bolts are renowned for their robustness and are designed to be driven with a wrench or socket that can efficiently transfer greater torque than other drive types. They are engineered to provide a high degree of precision and strength, regardless of whether they are driven into tapped holes or used in conjunction with nuts to clamp components together. They are indispensable in numerous industries, from automotive to architecture, due to their ability to withstand high levels of torque, making them ideal for heavy-duty applications.
