What are Grade 5 bolts rated for?
Grades of Bolts – Bolt Grade Markings & Bolt Strength Chart
| Bolt Grade Markings & Strength Chart – Inch Steel Bolts | ||
|---|---|---|
| Bolt Grade / Specification | Material | Proof Load psi |
| Grade 5 – SAE J429 Bolts, Screws and Studs | Medium carbon steel or carbon steel with additives, quenched and tempered | 85,000 74,000 |
What type of steel is Grade 5?
medium carbon
Grade 5 alloy steel is a medium carbon zinc plated alloy steel that is heat treated to increase hardness. Grade 5 bolts have three (3) evenly spaced hash marks on the head markings (manufacturers mark may also be included).
What is J429?
SAE J429 is a Society of Automotive Engineers specification for fasteners. SAE J429 covers fasteners sizes up to 1-1/2″ inclusive. Used in automotive and related industries, these fasteners can be found in small quantities in automotive and home improvement stores.
How would you identify a Grade 5 SAE bolt?
SAE Grade 5 Bolts: Head Marking: Three radial lines. Material: Medium carbon steel, quenched and tempered….SAE Bolt Grades
- Head Marking: No marking.
- Material: Low or medium carbon steel.
- Size Range: 1/4-inch to 3/4-inch.
What is SAE grade 5?
SAE steel bolts – grades ranging grade 1 to 8.2 – proof and tensile strength
| SAE Grade | Size Range (in) | Minimum Tensile Strength (103 psi) |
|---|---|---|
| 2 | 1/4 – 3/4 7/8 – 1 1/2 | 74 60 |
| 5 | 1/4 – 1 1 1/8 – 1 1/2 | 120 105 |
| 5.2 | 1/4 – 1 | 120 |
| 7 | 1/4 – 1 1/2 | 133 |
How many PSI is a grade 5 bolt?
Grade 5 – Unlike grade 2 bolts, grade 5 bolts feature 5 radial lines. These bolts are manufactured from medium carbon steel. These bolts come in two different size ranges – 1/4″ to 1″ and 1″ to 1 1/2″, which have the proof load of 85000 psi and 74000 psi respectively.
What is SAE Grade 5?
What is SAE J995?
SAE J995 Grade 2 hex nuts are an economical, common low strength nut manufactured from low carbon steel. Grade 2 hex nuts are available in diameters from 1/4″ through 1 1/2″ inclusive. Dimensional specifications are governed by ASME B18. 2.2.
What is the difference between Grade 2 and Grade 5 bolts?
Grade 2 is a standard hardware grade steel. This is the most common grade of steel fastener and is the least expensive. Except a possible manufacturer’s mark,Grade 2 bolts have no head marking. Grade 5 bolts are hardened to increase strength and are the most common bolts found in automotive applications.
Is a Grade 5 bolt strong?
Grade 5 bolts are hardened to increase strength and are the most common bolts found in automotive applications.
What is SAE specification?
SAE is the Society of Automotive Engineers. An SAE grade (probably from an SAE standard or specification) is identifies motor oil properties that defines its weight and viscosity and other properties, like SAE 10W-30.
The Grade 5 specification falls under the Society of Automotive Engineers (SAE) classification system, while A325 is an ASTM specification. ASTM A325 bolts are more commonly specified by engineers for use in structural steel connections on heavy construction projects, while SAE Grade 5 bolts are more common in OEM-type applications.
What is SAE grade 5 bolt?
Grade 5 bolts are a medium hard bolt and have 3 lines on the head. Grade 8 bolts are made out of alloy steel and heat treated to a real high tensile. Grade 8 bolts have 6 lines on the head. The specification number SAE J429 is the standard that covers these grades, and many other grades that are not as commercially available as these three are.
