    Types of Nut Bolts

    What is a high tensile bolts?

    Most often, customers looking for a high tensile bolt may just be looking for the 8.8 grade. · S- An S grade refers to the tensile strength of industrial fasteners, or the maximum amount of stress these fasteners and fixing can withstand before they begin to break or fail.

    Tensile Bolt Grading

    When purchasing high tensile bolts, there are two main grades you should be aware of: ‘S’ and ‘8.8’ Many times, two fasteners and fixings look and feel the same, and there’s a reason why.
    · 8.8- This type of grade is often referred to as the structural grade for bolts. These types of bolts often have galvanised hexagon heads, and most are made with zinc or are zinc plated. To identify this grade, look out for an ‘8.8’ stamp or a set of three radial lines on the head of the bolt. Most often, customers looking for a high tensile bolt may just be looking for the 8.8 grade.
    · S- An S grade refers to the tensile strength of industrial fasteners, or the maximum amount of stress these fasteners and fixing can withstand before they begin to break or fail. When a bolt has a grading of S, it means that it can withstand a stress of 45 to 49.9 metric tonnes per 6.45 cm². This grading, which is typically stamped on the head of the bolt, has the same tensile strength as a grade 8.8 bolt.

    Bolts labelled with the grade 8.8 or S are solid, heavy duty bolts that can be used for a variety of tasks. However, it is important to understand that other grades are also available, although perhaps not used as often.
    · 4.6- These types of bolts are considered to be commercial grade and are not as strong as an 8.8. In vehicles, they are often used to hold light objects like trim. Most customers will not need this type of bolt except in circumstances where strength is not an issue.
    · 12.9- These fasteners and fixings are meant for the heaviest jobs, like securing engines and ensuring drives are tamper proof.
    · R- This grading can withstand 40.8 to 45 metric tonnes per 6.45 cm², and while it used to be popular, it is now quickly being replaced with the more common and efficient S grade.

    What does 8.8 on the head of a bolt mean?

    Markings on Hex Bolt Heads

    What do those slashes and numbers generally mean on a hex bolt? It’s very simple, generally speaking on a clear zinc plated bolt you will notice 3 hash markings on the head. This represents grade 5 which carries a tensile strength of 120,000 psi. A gold color zinc plated bolt has 6 hash markings on the head this represents grade 8 which carry a tensile strength of 150,000 psi. Is there a stronger bolt than grade eight? Yes, there is a F-911 hex bolts and 12 point flange bolts that are rated between 180,000 & 190,000 psi tensile strength.
    Now to really screw things up for all of us that have Harley Davidson’s, the v-rod has many metric fasteners. If you have ever looked a metric hex bolt you might notice the markings 8.8, 10.9 or 12.9 this does not mean grade 8,10 or 12. The grade 8.8 refers to the tensile strength which is generally 116,000 psi, grade 10.9 is generally 150,000 and grade 12.9 is generally 175,000 psi.
    Now what about stainless steel bolts? Well 18-8 stainless is great for corrosion resistance and polishes up to a brilliant finish but is not extremely strong. Generally speaking most of the stainless fasteners are 18-8 and carry a 100,000 tensile strength. Do they make a stronger tensile strength stainless? Yes and the answer is ARP or Automotive Racing Products has stainless fasteners rated at 170,000 psi tensile strength ..

    What is high tension bolt?

    A bolt that is adjusted to a carefully controlled tension by means of a calibrated torsion wrench; used in place of a rivet. Also known as high-tension bolt.

    Head Marking Grade and Material Nominal Size Range (inches)
    3 Radial Lines Grade 5 Medium carbon steel, quenched and tempered 1/4" thru 1"
    Over 1" thru 1-1/2"
    6 Radial Lines Grade 8 Medium carbon alloy steel, quenched and tempered 1/4" thru 1-1/2"
    What is 4.6 grade in bolts?

    For metric bolts strength is described by "property classes" with designations 4.6, 4.8, 5.8, 8.8, 9.8, 10.9 and 12.9.

    Class Size Range

    • 1 Pa = 1 N/m2 = 1.4504x10-4 lb/in2 (psi)

    What does class 10.9 bolt mean?

    Our metric grade 10.9 bolts meet ASTM A324 grade BD and SAE J429, grade 8 standards. The yield strength of the bolts is 940 and the tensile strength is 1040 MPa. U-Bolt-It is a leading distributor and manufacturer of high quality metric grade 10.9 bolts.

    What is high tensile strength?

    Tensile strength is a measurement of the force required to pull something such as rope, wire, or a structural beam to the point here it breaks. The tensile strength of a material is the maximum amount of tensile stress that it can take before failure, for example breaking.

    What does m8 mean on a bolt?

    The size of a metric fastener (screw, bolt, etc.) is specified as diameter, pitch and length, all in millimeters (millimeters is abbreviated "mm"). An exception involves coarse threaded fasteners, in which case only the diameter and length may be listed (coarse threads is then assumed). Consider this size… M8-1.0 x 20.

    What is a high tensile bolts?

    Most often, customers looking for a high tensile bolt may just be looking for the 8.8 grade. · S- An S grade refers to the tensile strength of industrial fasteners, or the maximum amount of stress these fasteners and fixing can withstand before they begin to break or fail.

    What is high tension bolt?

    A bolt that is adjusted to a carefully controlled tension by means of a calibrated torsion wrench; used in place of a rivet. Also known as high-tension bolt.

    What is the meaning of 8.8 grade in a bolt?

    These are grade 4.6 and 8.8. The first digit relates to the ultimate strength of the material, whilst the second is the ratio of yield stress to ultimate strength. Thus grade 4.6 bolts have an ultimate material strength of 400N/mm2 and the uield (or proof) stress is 60% of the ultimate strength.

    What does 8.8 mean on the head of a bolt?

    If you have ever looked a metric hex bolt you might notice the markings 8.8, 10.9 or 12.9 this does not mean grade 8,10 or 12. The grade 8.8 refers to the tensile strength which is generally 116,000 psi, grade 10.9 is generally 150,000 and grade 12.9 is generally 175,000 psi.
