BOLT Fasteners

We offer a full selection of bolts for sale, covering various materials, sizes, and designs to meet diverse industrial, construction, and DIY needs. Our inventory includes different types of bolts such as hex bolts, carriage bolts, anchor bolts, and stud bolts, as well as specialized types of door bolts for security and furniture applications.

Bolts come in different head styles, and we supply all different types of bolt heads, including hex head, square head, countersunk head, and flanged head. For threaded connections, we provide a wide range of bolt thread types and types of screw thread, such as UNC, UNF, metric coarse, metric fine, and trapezoidal threads, to suit both mechanical and structural requirements.

Our stud bolt types are ideal for flanged connections in pipelines and pressure vessels, while decorative and functional door bolts ensure security in residential and commercial doors. All products are manufactured to ISO, DIN, ANSI, and ASTM standards, ensuring durability and precision.

Available in carbon steel, stainless steel, alloy steel, and brass, with finishes such as zinc plating, galvanizing, and black oxide, our bolts deliver reliable performance in harsh environments.

Angle Bolt Sizes

Angle bolts are specialized fasteners commonly used in construction, metal fabrication, and structural assemblies where two components must be joined at an angle, often with angle irons or brackets. Understanding angle bolt sizes is crucial for ensuring proper fit, load capacity, and long-term reliability of the joint. The size of an angle bolt is typically defined by its diameter, length, and thread pitch. Diameter refers to the thickness of the shank, usually specified in millimeters for metric bolts (e.g., M8, M10, M12) or inches for imperial bolts (e.g., 3/8", 1/2"). Length is measured from the underside of the bolt head to the end of the threaded portion, while thread pitch (or threads per inch in imperial systems) indicates how closely spaced the threads are. In addition to these dimensions, angle bolts often come in different head styles, such as hex heads for wrench tightening or carriage-style heads for flush finishes. Charts and standards, such as ISO, DIN, and ANSI, provide exact measurements for width across flats, head height, and tensile strength, ensuring compatibility across applications.

Are Anti-Theft Bolts Worth It?

 

Anti-theft bolts, also known as security bolts or tamper-resistant bolts, are designed with unique head patterns that require special tools for installation and removal. They are widely used in applications where preventing unauthorized access, theft, or tampering is a priority. Examples include securing public fixtures, license plates, outdoor equipment, electronics, and high-value assets.

The main advantage of anti-theft bolts is the added layer of security they provide. Standard bolts can be removed with common tools like wrenches or screwdrivers, but anti-theft bolts require special driver bits, making it much harder for thieves or vandals to tamper with them. This added difficulty often acts as a deterrent, protecting valuable items and reducing replacement or repair costs.

While anti-theft bolts may be more expensive than standard fasteners, their long-term benefits often outweigh the initial cost. For example, replacing stolen equipment or repairing vandalized property can be significantly more costly than investing in tamper-proof fasteners upfront. Additionally, many anti-theft bolts are manufactured from high-strength stainless steel or alloy steel, ensuring both durability and corrosion resistance in outdoor environments.

However, one drawback is that maintenance or authorized removal requires the correct tool, which must be kept secure to avoid inconvenience. For projects requiring frequent adjustments, standard bolts may still be more practical.

In conclusion, anti-theft bolts are worth it when security and protection are critical. They provide peace of mind, reduce theft-related losses, and help maintain long-term reliability of valuable installations.
