What is SAE J995?
SAE J995 Grade 5 hex nuts are medium strength nuts manufactured from quenched and tempered medium carbon steel. Grade 5 hex nuts are available in diameters from 1/4″ through 1 1/2″ inclusive. Dimensional specifications are governed by ASME B18.
Is there a grade 8 nut?
Class 8. This is a metric nut grading similar to the SAE grade 5 classification, which is used in conjunction with Class 8.8 bolts. This is a medium strength nut.
What is ASTM a563 Grade A?
Governing StandardsGrade A Covers the chemical and mechanical requirements for eight grades of carbon and alloy steel nuts for general structural and mechanical uses on bolts, studs, and other externally threaded parts.
What material is a Grade 8 bolt made of?
medium carbon alloy steel
Grade 8 – Grade 8 bolts are made from medium carbon alloy steel. The bolts of this grade feature 6 radial lines. The nominal size of the grade 8 bolts can be from 1/4″ to 1 1/2″. The minimum yield strength of this grade bolt is 130,000 psi.
Is Class 8 and Grade 8 the same?
Q: I’m specifying the strength of a metric fastener and need your help. Is Class 8.8 the same as Grade 8? A: The answer is no. Class 8.8 is not the same as Grade 8.
Is A194 stainless steel?
The ASTM A194 specification covers a variety of carbon, alloy, and martensitic stainless steel nuts in the size range 1⁄4 through 4 in.
What is SAE grade bolts?
SAE Bolt Grades—The standards for bolt strength grades in the U.S. are set according to a system developed by the SAE (Society of Automotive Engineers). The SAE marking system uses raised dashes on the bolt head to indicate strength.
Are Grade 8 bolts rust resistant?
Many other grades exist but are used far less often. Grade 2, 5, and 8 are usually plated with a slightly blue-ish or yellow zinc coating, or are galvanized, to resist corrosion. Bolts are typically marked on the head to show what grade bolt they are.
What does A194 mean?
The ASTM A194 specification covers carbon, alloy, and stainless steel nuts intended for use in high-pressure and/or high-temperature service. Unless otherwise specified, the American National Standard Heavy Hex Series (ANSI B 18.2. 2) shall be used.
Is Grade 8 the same as B7?
It is also quenched and tempered at 800 F leading to its strength. Grade 8 has 0.28-0.55% carbon, 0.030% max phosphorus, and 0.050% max sulfur….Grade 8.

Is A193 B8 stainless steel?
ASTM A193 Grade B8 is a standard material specification for corrosion resistant austenitic stainless steel fasteners, for use in high tensile, high temperature and special purpose applications such as pressure piping & pressure vessels bolting.
What is SAE 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 a Grade 8 bolt stronger than stainless steel?
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.
