What do the letters on bolts mean?
You can usually figure out the grade, or strength, of a bolt by looking at the markings on its head. English bolts (U.S.S. or S.A.E) are categorized by grade, from grade 2 to grade 8, where the grade represents inch strength. The higher the grade, the stronger the bolt.
What does 8.8 JH mean on a bolt?
A property class (PC) is the metric equivalent of a grade in inch series terminology. So, in English, a PC 8.8 bolt is a bolt with a nominal tensile strength of 800 MPa and a nominal yield strength that is 80% of the bolt’s nominal tensile strength, or 640 MPa.
What is a 10.9 JH bolt?
Grade 10.9 Bolt is a high tensile bolt. These are made up of carbon steels and low boron steels. The material is heat treated by quenched and tempered methods. The bolts are produced in a way that they have high tensile strength.
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. This sought-after grade 8 bolt can be distinguished by six raised dashes.
What is a F593 bolt used for?
These ASTM F593 18-8 Bolts specified bolts are used for either high temperature or high pressure service, or other special purpose applications including the use of the ASTM F593 Threaded Rod in applications such as pressure vessels, valves, flanges, as well as fittings.
What does ASTM F593 stand for?
ASTM F593/ ASTM F593C Stainless Steel Bolts ASTM F593 covers the chemical and mechanical requirements for stainless steel bolts, hex cap screws and studs in diameters ranging from 1/4″ to 1-1/2″ inclusive. ASTM F593 Alloy Groups ASTM F593 Mechanical Properties / Condition
Are the ASTM F593 stainless steel bolts heat treated?
The Ferritic ASTM F593 Stainless Steel Bolts must be properly heat treated in a manner that best suits the high temperature characteristics of each stainless steel grade.
What is the yield strength of F593 fasteners?
These fasteners generally have an ASTM F593 Yield Strength which is roughly about 20% more as compared to the usual 18-8 fastener. Besides being susceptible to crevice corrosion, another common problem with many stainless steel grade fasteners that they tend to become susceptible to pitting corrosion as well.
