What is a Grade 5 fastener?
Grade 5 Bolts and fasteners are made of medium strength carbon steel and are specified under the Society of Automotive Engineers (SAE). These bolts are heat treated in a controlled atmosphere from 1⁄4 in. through 1-1/2 in. with a minimum tensile strength of 120,000 psi in diameters through 1 in.
What are Grade 5 bolts used for?
These bolts are generally used for non-critical joints and applications. A grade 5 bolt is distinguished by 3 radial lines and promises tensile strengths between 105,000 and 120,000 psi. They are most commonly found in automotive applications.
What is the tensile strength of Grade 5 bolt?
Bolt Grade Markings and Strength Chart
| Head Marking | Grade and Material | Mechanical Properties |
|---|---|---|
| Min. Tensile Strength (psi) | ||
| No Markings | Grade 2 Low or medium carbon steel | 60,000 |
| 3 Radial Lines | Grade 5 Medium carbon steel, quenched and tempered | 120,000 |
| 105,000 |
What material is a Grade 5 bolt?
Carbon Steel Bolt Grade Markings
| Specification | Material | Proof Load Stress (ksi) |
|---|---|---|
| ASTM A307 – Grade A | Low or Medium Carbon Steel | – |
| ASTM A307 – Grade B | Low or Medium Carbon Steel | – |
| SAE J429 – Grade 5 | Medium Carbon Steel, Quenched and Tempered | 85 |
| ASTM A449 – Type 1 | Medium Carbon Steel, Quenched and Tempered | 74 |
Is grade 8 or Grade 5 stronger?
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.
Is Grade 5 the same as A325?
Grade 5 bolts are usually available in a finished hex bolt design; A325 bolts must have a heavy hex head. The nuts required for grade 5 bolts are a finished hex pattern, whereas A325 bolts need heavy hex nuts such as A192-2H or A563-DH. Grade 5 bolts specify bolts from .

Is Grade 5 a good bolt?
Grade 5 bolts are hardened to increase strength and are the most common bolts found in automotive applications.
Will a Grade 5 bolt rust?
Steel is the most common fastener material. Steel fasteners are available plain as well as with various surface treatments such as zinc plating, galvanization, and chrome plating. Grade 2, 5, and 8 are usually plated with a slightly blue-ish or yellow zinc coating, or are galvanized, to resist corrosion.
Will a Grade 5 bolt shear?
For example, an SAE grade 5 hex cap screw has a specified minimum tensile strength of 120,000 psi. Therefore, for design purposes, its shear strength could be reasonably assumed to be 70,000 psi.”
