What grade bolt is a F593C?

3/8″-16 x 1-1/2″ Plain Finish ASTM F593C Grade 18-8 Hex Washer Flange Bolt | Fastenal.

What does F593C mean on a bolt?

The F593C marking means the bolt was made to meet an ASTM standard defining what it’s made of and how strong it will be. A superior bolt then the common hardware store bolt.

What grade is a zinc bolt?

Hex Bolt – Grade 2 – Zinc – Reliable Fasteners.

What grade bolt is s30400?

Grade 304 is a standard “18/8” stainless. It is the most versatile and most widely used stainless steel available, even though a wide range of alternatives are available; and has excellent forming and welding characteristics.

Is a stainless bolt harder than a Grade 8 bolt?

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.

What are the different bolt grades?

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. No matter the system used to grade the bolts, the higher number means the stronger the bolt.

How do you tell the grade of a bolt?

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 is meant by 8.8 grade bolt?

In the case of a 8.8 grade bolt the first figure signifies that the Tensile Strength is at least 800MPa. The second figure signifies that the fastener will begin to yield at 80% of the Ultimate Tensile Strength, i.e. at least 640MPa.

What is a Grade 5 bolt?

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.

Is Grade 8 the strongest bolt?

Commercial-grade 8 bolts are the strongest option available. They’re made from medium carbon alloy steel and have markings that include six raised dashes. The psi of the bolt is 150,000, meaning that it can withstand great deals of pressure because of the way it was quenched and tempered.

Which is better 304ss or 316ss?

Though the stainless steel 304 alloy has a higher melting point, grade 316 has a better resistance to chemicals and chlorides (like salt) than grade 304 stainless steel. When it comes to applications with chlorinated solutions or exposure to salt, grade 316 stainless steel is considered superior.

What does S30400 mean on a bolt?

ASTM A182 UNS S30400 is a forging material specification for S30400 grade stainless steel and is used for manufacturing bare forgings or forged and machined products for applications involving high temperature service.

What grade are black bolts?

The colour black, referred to the fact the steel used to make the bolts was not finished with any corrosion protection, although zinc plating is a common finish for durability. The grade 4.6, relates to the strength of the bolts.

Will Grade 8 bolts rust?

Grade 8 Steel Bolts

Grade 8 bolts have 6 evenly spaced radial lines on the head.” Unlike stainless steel, which is highly resistant to corrosion, steel, however reinforced, will oxidize over time and rust. Grade 8 bolts that are not galvanized or plated with yellow zinc, however, are cheaper.

What is the strongest metal for 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.

Will stainless steel rust?

Stainless steel remains stainless, or does not rust, because of the interaction between its alloying elements and the environment. … These elements react with oxygen from water and air to form a very thin, stable film that consists of such corrosion products as metal oxides and hydroxides.
