Keeping this in consideration, what grade are Home Depot bolts?
There are several grades of bolts but the three common grades for SAE are 2, 5 and 8. The common class (grades) for metric are 5.8, 8.8, 10.9 and 12.9. Each grade has a specific bolt strength.
Furthermore, are stainless bolts stronger than Grade 8? Stainless steel bolts are rated for corrosion resistance. Bolt strength is rated in PSI (pounds per square inch). A stainless steel bolt has the same PSI rating as a grade 5 bolt (125,000 PSI). A grade 8 bolt has a stronger rating with a PSI of 150,000.
Likewise, people ask, how can you tell if a bolt is grade 8?
Look for Bolt Markings If you do not have a magnet you can still identify Grade 8 bolts by brushing the head of the bolt using a wire brush and counting its radial lines. There are six radial lines on the heads of Grade 8 bolts. Length is measured from under the head.

What are the strongest grade bolts?
The strongest commercial-quality bolt is grade 8, marked by six raised dashes; its medium-carbon alloy steel has been quenched and tempered to achieve a tensile strength of 150,000 psi.Is there a grade 10 bolt?
There's no such thing as a grade 10. There's a 10.9 in metric. From the course I sat thru a couple months back grade 8 is the strongest bolt grade for SAE sizes.What does 8.8 mean on metric bolts?
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.What is the meaning of 8.8 grade in a bolt?
8.8 is ISO 898–1 grading for Bolts and screws. It indicates a bolt/screw with tensile strength of minimum 800MPa and a yield strength of 80% of 800MPa = 640MPa. Depending on thickness these are either quenched and tempered or can also be used without Q&T provided they meet the hardness and tensile requirements.What is the difference between Grade 5 and Grade 8 bolts?
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. Grade 8 bolts have 6 evenly spaced radial lines on the head. Grade G is roughly equivalent to Grade 8.What is a Grade 5 Screw?
Grade 5 Bolts and fasteners are made of medium strength carbon steel and are specified under the Society of Automotive Engineers (SAE). If your application calls for heavier materials, you may need Grade 8 Bolts because they are the hardest and are often used in heavy manufacturing applications.What grade are Everbilt bolts?
Overview. These Grade 8 cap Screw are recommended for high stress bolting applications and are the among the strongest grade of fastener available in steel. The grade 8 bolt is compatible with grade 8 Nut and Washer of the same thread pitch and diameter.Is Grade 8 or 10.9 stronger?
Class 10.9 is stronger than class 8.8, and is commonly found in high strength automotive applications. Class 10.9 is similar to grade 8. A low carbon steel for general use.What material is a Grade 8 bolt made of?
From the internet: Grade 8 bolts are comprised of carbon alloy steel, thus giving them a high psi rating. Zinc or yellow zinc grade 8 bolts are available to resist corrosion. The factor that makes a grade 8 bolt different from a lower grade bolt is its preload strength.How much weight can a 3/8 bolt hold?
SAE Bolt Strength| Bolt Safe Working Loads (lbs) (Safe tensile load at 6,000 psi load) (Safe shear strength at 7500 psi load) | ||
|---|---|---|
| BoltDia(in) | NF Thread Grade 2 Iron Bolt | |
| 1/4 | 200 | 370 |
| 5/16 | 340 | 575 |
| 3/8 | 510 | 830 |
What is the tensile strength of a Grade 8 bolt?
Grade 8 bolts are designated as a 150 ksi. This means its tensile strength or the resistance it has before it is subject to breaking under tension is equal to 150,000 lbs. per square inch. In comparison, a Grade 5 bolt is weaker as its tensile is 120 ksi, placing it at 120,000 lbs.Is 8.8 bolt high tensile?
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.What color is a Grade 8 bolt?
Grade 8 bolts are made of a medium carbon alloy steel that is also quenched and tempered and are the most durable bolts you can purchase for automotive use. They can be identified by the five radial lines on the head of the bolt and are usually (but not necessarily) gold in color.What is the hardest grade bolt?
Bolt Grade Markings and Strength Chart| Grade and Material | Mechanical Properties |
|---|---|
| Proof Load (psi) | |
| Class 8.8 Medium carbon steel, quenched and tempered | 600 |
| Class 10.9 Alloy steel, quenched and tempered | 830 |
| Class 12.9 Alloy steel, quenched and tempered | 970 |
