Bolts

THV Fasteners supplies an extensive selection of industrial bolts, available in a wide range of materials, head shapes, and sizes. All of our bolts are crafted from high-quality materials to ensure a secure connection in even the most demanding applications. Each bolt option is suited for numerous applications to fit any project’s needs. Our available bolt options are detailed below.

Hex Head Cap Screws Hex head cap screws are six-sided fasteners with a washer face under the head and a chamfered end, available as either partial or fully threaded. They are renowned for their high strength and reliability in demanding tasks. Our hex head cap screws are available in a wide range of steel and stainless steel, with different grades, finishes, lengths, and pitch options.

Heavy Hex Bolts Heavy hex bolts are externally threaded fasteners designed with a larger head for superior load distribution, often used in high-pressure and high-temperature applications. We offer heavy hex bolts in various diameters, lengths, grades, finishes, and pitch options.

Structural Bolts Engineered to perform reliably under extreme pressure and environmental stress, our structural bolts are manufactured from DIN, ASTM A325 and A490 equivalent materials. These bolts are our core products for critical, load-bearing applications. Structural bolts are available as heavy hex bolts or tension control bolts in many diameters, lengths, grades, and finish options.

Flange Bolts Flange bolts are designed to deliver reliable fastening with an integrated washer-like flange under the head, making them ideal for high-vibration applications and heavy-duty assembly. This design reduces the need for separate washers. Our flange bolts are available in various diameters, lengths, materials, and finish options.

Carriage Bolts Carriage bolts are round-head bolts with a square neck, typically used in metal-to-wood connections where the square neck prevents the bolt from turning when tightened. Carriage bolts are offered in various materials such as stainless steel or steel, with different diameters, lengths, grades, and finish options.

Plow Bolts Plow bolts have a square neck that keeps the bolt from turning during tightening, making them essential for heavy equipment like plows, bulldozers, and excavators. THV Fasteners provides plow bolts with various diameters and lengths in either Grade 5 or 8.

Square Head Machine Bolts Square head machine bolts are threaded fasteners with a four-sided head. These bolts are typically used in mechanical assemblies, construction, and as a decorative alternative in restoration projects. We offer square head machine bolts in different diameters and lengths, Grade 2 or 5, and with plain or zinc finishes.

Elevator Bolts Elevator bolts are designed with a flat, thin, and wide round head for applications requiring a flush surface. These bolts are typically used for fastening components in conveyor systems or other applications needing a low-profile connection. Our elevator bolts are available in various diameters and lengths, Grade 2, with either plain or zinc finishes.

Tap Bolts Tap bolts are fully threaded hex bolts designed to be screwed into a tapped hole, eliminating the need for a nut. They are ideal for applications where a nut is impractical. Our tap bolts are available in many diameters and lengths, in steel or stainless steel, with various grades and finish options.
