Definition and characteristics of hexagon socket cap screw, Uses and Application Industries

Hexagon bolts, also known as hexagon head bolts, are a standard mechanical fastener with a hexagonal head, hence the name. Hexagonal bolts connect two or more parts by threading with a nut. Their definition and characteristics are as follows:

A hexagonal bolt is a bolt with six equal hexagonal heads and threads. Hexagon bolts are usually made of carbon steel, alloy steel, stainless steel, and other materials, as well as treatment and other processes to improve their strength and corrosion resistance.

Alloy Steel Socket Head Screws: With a tensile strength of 170,000 psi, these alloy steel screws are more robust than Grade 8 steel screws. Length is measured from under the head.

Black-oxide steel screws are mildly corrosion-resistant in dry environments. Zinc-plated steel screws resist corrosion in wet environments. The screws with a blue-dyed finish are easy to distinguish. Zinc-flake-coated steel screws are 20 times as corrosion-resistant as zinc-plated screws and comparable to Dacromet-coated screws.

Coarse threads are the industry standard; choose these screws if you don't know the pitch or threads per inch. Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance. They are not compatible with coarse threads.

Screws that meet ASTM A574, ASTM A574M, and ISO 898-1 comply with specifications and testing requirements for material quality. Screws that meet ASME B18.3, ASME B18.3.1M, ISO 21269, and ISO 4762 (formerly DIN 912) comply with specifications for dimensional standards.

18-8 Stainless Steel Flanged Hex Head Screws for Sheet Metal:18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. They have a hex head for a secure grip with a wrench and a flange to reduce the risk of crushing thin metal. Screws penetrate 0.025" and thinner sheet metal. Length is measured from under the flange. Head height includes the flange.

Torx Flat Head Thread-Cutting Screws for Metal: A Torx drive has more points of contact than a Phillips drive, allowing you to apply extra force with less slippage or damage to the recess. These screws are beveled under the head for use in countersunk holes. How to remove hexagon screws, They cut threads in drilled holes as they're turned, so they require less driving torque and cause less stress on your material than thread-forming screws. Length is measured from the top of the head.

Screws with a black-phosphate finish provide mild corrosion resistance in dry environments.

Screws with a zinc-plated finish resist corrosion in wet environments.

Hexagon head bolts feature:

1. High strength: hexagonal bolts are usually made of high-strength materials, capable of withstanding large forces and pressures to ensure the firmness and reliability of the connection.

2. Hexagonal head design: The head of hexagonal bolts is hexagonal in design. This shape makes the bolts easier to tighten with a wrench, providing better force transmission and control.

3. Threaded connection: Hexagonal bolts and nuts are connected by threads, which provide high tensile and shear strength and ensure firmness between the connected parts.

4. Multiple sizes and specifications: Hexagon bolts are available in a wide range of sizes and specifications to meet different connection needs. Common sizes include diameter, thread length, and thread size.

5. Wide range of applications: Hexagon bolts are widely used in machinery, construction, automotive, motorcycle, aerospace, and other fields. Whether a large-scale project or a minor assembly, hexagonal bolts play an important role.

The definition and characteristics of hexagonal bolts make them a commonly used mechanical fastener in various industries. Their high strength, hexagonal head design, threaded connections, and diverse sizes and specifications provide them with good fastening ability and adaptability. This is of great significance for safeguarding the safety and stability of equipment and structures. With the continuous progress of science and technology, hexagonal bolts in future development are expected to further enhance their performance and scope of application.
