What is Hex Bolts (Hexagon Bolts)?

Hexagon bolts also known as Hex Bolts are used to secure objects, and a threaded nut is used to tighten and maintain their position (and often a washer). The plain part of the shank varies in length.

When it comes to building and repair, hex bolts—also known as hexagon screw head bolts, hex cap bolts, hex-cap screws, or machine bolts—are a popular option. There is a wide range of sizes and diameters available for hexagon screw head bolts.

The manner in which these fasteners are installed is the fundamental distinction between a cap screw and a bolt. Technically speaking, a cap screw is inserted by twisting the head of the bolt to assemble and tighten, whereas a bolt is installed by turning a nut to tighten the fastener.

Bolts have more gripping power than screws. This is partially a result of the washer’s presence, which disperses the load over a greater surface area. Bolts are effective for heavy-duty, load-bearing applications because they provide higher strength.

With a conventional wrench, you need to grip the bolt’s head on both sides to loosen or tighten it. Hexagonal heads give additional surfaces to grab with a standard wrench since they have more sides than square heads. Hex bolts are now simpler to utilise in tight areas. Additionally, more torque is possible with hex bolts.

Tempered medium carbon steel Class 8.8 is weaker than classes 10.9 and 12.9. High strength automotive applications frequently use it, Hex nuts Machine bolts and hex bolts are cylindrical fasteners that are used to secure two pieces of metal together. Hex bolts feature machine threads that can be used with nuts or in a tapped hole and have hexagonal heads.

Medium carbon steel, medium carbon steel alloy, and low carbon boron steel that has been quenched and tempered are used in the production of metric grade 10.9 bolts. Metric 10.9 bolts, which are frequently used in automotive applications and for fastening massive, forged pieces, have a high tensile strength and good wear resistance., The force that a bolt can withstand while being stretched without deforming is known as its tensile strength. The maximum load without permanent deformation is known as yield strength. A 12.9 is about 20–25% stronger than a 10.9 and has a tensile strength value of 175000–180000 psi.

Stainless steel bolts and high tensile steel hexagon head bolts are both available. Extra-high tensile Grade 10.9 bolts are also available for important applications, but Grade 8.8 high tensile bolts are the industry standard. In descending order of corrosion protection, surface treatments include Self Colour (black oxidised and oiled), BZP (Bright Zinc Plated – transparent passivated), and Galvanized (thick zinc coating). You may discover details on the bolt dimensions for each product line, including instructions on how to determine how long the threaded section of the shank should be. Starting with M5, they go up to M36.
