What size is a 8.8 Bolt

Metric hex bolts, Zinc plated class 8.8 steel, 8mm x 1.0mm x 60mm.

What does 8.8 mean on a bolt?

So, in English, a PC 8.8 bolt is a bolt with a nominal tensile strength of 800 MPa and a nominal yield strength that is 80% of the bolt’s nominal tensile strength, or 640 MPa.

Is 8.8 high tensile?

High tensile steel bolts Grade 8.8 high tensile steel is often referred to as the structural grade for bolts. It is the most common form of high tensile material and is usually stocked in plain finish or zinc. It can be plated in many other coatings.

How much weight can a 8.8 bolt hold?

In round terms it is in 10’s of kg per square millimeter of the bolt. For example, a grade 12.9 bolt will not snap until every square millimetre of the bolt cross section is carrying a load of at least 120 kg. Similarly a grade 8.8 bolt will not snap until it is carrying a load of 80kg per square millimetre.

What grade is the strongest bolt?

Grade 9 structural bolts, also known as grade 9 hex cap screws, are one the strongest structural bolts that can be used today. While the typical grade 8 bolt has a tensile strength of 150,000 PSI, a grade 9 bolt has a tensile strength of 180,000PSI.

What are bolt grades?

The grade of a bolt determines the maximum amount of stress (tensile strength) that the bolt can handle. … The SAE marking system uses raised dashes on the bolt head to indicate strength. Metric Bolt Grades—Metric grades are set according to rules set by the ISO (International Standards Organization).

Is M8 screw 8mm?

There is an M sized bolt or screw that is 8mm in diameter. It is roughly the same as a 5/16 bolt or screw.

Is 8mm same as 5 16?

8mm = 5/16 inch. 9mm = almost 3/8 inch.

What kind of steel are Grade 8 bolts made of?

Grade 8 (SAE J429) is a medium carbon alloy steel with one of the highest tensile strengths available. With a minimum tensile strength of 150 ksi and a minimum yield of 130 ksi, Grade 8 has a higher tensile and yield strength than other steel grades such as Grade 5 and B7.

What does 1364 mean?

IS 1364 was originally published in 1960 and first revised in 1967. Subsequent to the publication of 1967 edition, many changes had been agreed upon at international level which have been reflected in IS 1367 series of standards covering ‘Technical supply conditions for threaded steel fasteners‘.

What grade is a metric 8.8 bolt?

Class 8.8 is similar to grade 5. Zinc plated for moderate corrosion resistance. A tempered medium carbon steel. Class 10.9 is stronger than class 8.8.

What are black bolts?

The term “black bolt” is an industry term for plain finish or no finish bolts. These bolts offer no corrosion resistance and will rust over time. If you are looking for a decorative coating that is actually black, you will want to specify that they are actually coated and state which kind of coating is necessary.

How can you tell if a bolt is grade 8?

English bolts have radial lines on their head to identify the grade, or strength class. The number of lines on the bolt head is 2 less than the actual grade. So, for example, a grade 5 bolt will only have 3 radial lines on its head. A grade 8 bolt will have 6 radial lines on its head.

Is Grade 8 bolts stronger than Grade 5?

Grade 8 bolts have been hardened more than grade 5 bolts. Thus they are stronger and are used in demanding applications such as automotive suspensions.

What does M mean for screws?

The standard metric rack screw is called M6 x 1. The ‘M’ means it’s metric. The ‘6’ is the outside diameter measured in millimeters, and the ‘1’ is the distance between adjacent threads, also in millimeters. Metric threads are used outside of the USA, and commonly in products by HP and other global entities.

How can you tell if a bolt is metric?

The metric screw thread is identified by the capital letter M, followed by the nominal diameter. Metric threads are measured by the distance between two adjacent threads in millimeters (pitch). Threads on a standard (inch based) fastener are measured by counting the number of threads per inch.
