12 best hex bolts
Hex bolts are a type of fastener commonly used in various industries for joining two or more parts together. They are a fundamental component of mechanical and structural applications, offering a secure and reliable connection. Here are some key characteristics and information about hex bolts:
Design: Hex bolts, also known as hexagon head bolts or hex cap screws, have a six-sided, hexagonal-shaped head. This design provides multiple flat sides for wrenches or socket tools to grip, making them easy to tighten and loosen.
Materials: Hex bolts are manufactured from a wide range of materials, including carbon steel, stainless steel, brass, and more.The choice of material depends on the specific requirements of the application, considering factors like corrosion resistance, strength, and cost.
Thread Types: Hex bolts can have different thread types, such as coarse threads (UNC) or fine threads (UNF). The thread type is selected based on the intended application and the load-bearing capacity required.
Length and Diameter: Hex bolts come in various lengths and diameters to accommodate different applications. The length is measured from the underside of the bolt head to the end of the threaded portion, while the diameter is measured across the threaded section.
Head Styles: In addition to the standard hex head, hex bolts are available in various head styles, including flange heads, which have an integrated washer-like flange for distributing load and providing a larger bearing surface.
Use Cases: Hex bolts are used in a wide range of applications, including construction, automotive, machinery, and electronics. They are often used to secure structural components, equipment, and machinery together.
Installation: Proper installation of hex bolts is crucial to ensure the integrity of the connection. This includes tightening them to the recommended torque specifications to prevent over-tightening or under-tightening.
Nut Compatibility: Hex bolts are typically used in conjunction with hex nuts. The nut and bolt combination creates a threaded connection that can be easily assembled and disassembled when needed.
Coatings and Finishes: Hex bolts can be coated or finished with various materials to enhance their corrosion resistance and appearance. Common coatings include zinc plating, galvanization, and black oxide.
Standards: Many industries adhere to specific standards when it comes to hex bolts. For example, the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO) have established standards for hex bolts to ensure uniformity and quality.
In summary, hex bolts are essential fasteners with a hexagonal head design that allows for easy tightening and loosening using wrenches or sockets. They come in various materials, sizes, and configurations to suit a wide range of industrial and mechanical applications, making them a versatile choice for securing components and structures.

| Answer: | These come from China. Thanks, Monster Fastener |
| Question: | Are these bolts grade |
| Answer: | Like most fastener suppliers, we do not specifically source Grade 2 bolts like we do with grades 5 & 8. We source a mix of grade 2 and A307 fasteners depending on what is currently available from suppliers. Grade 2 and A307 classes are almost identical in terms of specs and hardness and can be used interchangeably in most applications. To answer the question, these are either grade 2 or A307, either of which will work in your application |
