Grade 8.8 Bolts

What is Grade 8.8 Bolt?

Grade 8.8 depicts high tensile steel and it is often referred to as the structural grade for the bolts. The 8.8 Jh Bolt is one of the most common forms for any high tensile material and the Grade 8.8 Bolt is available in plain finish. The 8.8 grade bolt can be custom plated with several other coatings as per application requirements.

The 8.8 high tensile bolts grade is defined as the structural grade for bolts. The 8.8 lag bolt is large in size and they come with hexagonal heads. The 8.8 hex screw are bolts that come with six head and they help to fasten wood with wood and metal with wood. The anchor bolt grade 8.8 enables screw attachment to different brittle materials. The M20 Grade 8.8 Bolts have high hexagonal heads and they are also known as part-headed bolts. The 8.8 Cw Bolt is cold worked, which means they are formed under extreme pressure without any heating.

The Bolt and Nut Grade 8.8 are heat treated by quenching and tempering.

The M12 Grade 8.8 Bolts are metric bolts which are fractionally made under their given size. For example, the shank diameter of M16 Grade 8.8 Bolts is typically 15.97mm. The Hsfg Bolts Grade 8.8 are high-strength friction grip bolts that are tightened to induce pre-defined tension in the bolt shank. Due to the tension present in the 8.8 Screw Bolt, the interface present between the piles is unable to move relative to each other. This occurs because of the fractional resistance of the Grade 8.8 Bolts.

The Structural Bolts grade 8.8 are primarily designed for offering structural connections between steel and steel. The high tensile bolt grade 8.8 is famous for its durability, as it is used for firmly and safely holding two components together. The 8.8 Allen bolt comes with a hexagonal socket and is designed to be used with an Allen wrench. Thus, the bolt nut grade 8.8 is used in heavy projects, for fastening different types of heavy structures.

How to calculate the ultimate strength of an 8.8 grade bolt?

The hdw 8.8 bolt refers to the tensile strength, which is generally 116000 PSI.

What does HDW 8.8 mean on a bolt?

The HDW 8.8 bolt is under safety critical fasteners that are primarily used for the oil and gas industry.

Is 8.8 metric bolt high tensile?

The 8.8 metric bolt is a high tensile bolt.

Which of the following are advantages of 8.8 high tensile bolts thread rolling?

The advantages of rolled thread bolt grade 8.8 are that they are smoother and more resistant to damage during handling than cut thread. The rolled thread 8.8 Bolt also has increased wear and fatigue resistance, along with enhanced shear, and tensile and yield strengths.

Difference between 8.8S and grade 8.8 hex bolt

8.8 Hex Bolt grade defines high tensile steel, whereas the 8.8S denotes high-strength structural bolts, which have a large series of hexagonal heads.

Why is an anti-seizing test required for grade 8.8 fasteners?

Why is an anti-seizing test required for grade 8.8 fasteners?

Anti-seizing test is required on the grade 8.8 fasteners for preventing galling, seizing, corrosion, and lubricating for easing out the disassembling process.

Difference between EN 15048, ASTM F568, IS 3757 and BS 3692 grade 8.8

  • The EN 15048 grade 8.8 fasteners are non-tension ones that are designed for steel structures.
  • The ASTM F568 Grade 8.8 is an international standard for metric bolts used in general engineering applications.
  • The IS 3757 Grade 8.8 is a specification for high tensile grip fasteners which are mainly used in structural engineering.
  • The BS 3692 grade 8.8 standard specifies the physical and chemical properties of the nuts that come with coarse thread and fine pitch thread.

What are 8.8 galvanized bolts?

The 8.8 galvanized bolts have a thin layer of zinc coating.
