19 Nov 2013 Strength Grades for metric fasteners are designated by a symbol comprised of 2 numbers, separated by a decimal. For example, 4.6 and 8.8. The Thomas Register lists hundreds of firms under Metric Fasteners, Metric Screws, and Metric Bolts. The Industrial Fasteners Institute (IFI) has guides for fastener 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 Where high quality touches all levels of your business! In 2014, AALL AMERICAN Fasteners completed the rigorous process of becoming certified to ISO 9001: Property Class, SAE J429-Grade 8. Hardness (HRC), 33-39. Surface Hardness ( 30N), 58.6 max. Tensile Strength (psi), 150,000 min. Yield Strength at 0.2% A 12.9 bolt is one of the highest grade of bolts produced. Known for their high The strength of a 12.9 bolt is rated in MPa, or megapascals. A Megapascal is Corrosion resistance of special grade A2 and A4 stainless steel 21 - Steel grades for fasteners with assignment to steel groups following DIN EN ISO 3506.
5" Grade 8 bolt. Good item and good price. No complaints. I would question if they really meet Grade 8 specs. They may, but i had to cut and grind Grade 2 and A307A (A307 Grade A) Fasteners are both relatively low strength, non-heat treated carbon steel fasteners which have similar strength and
Dan-Loc Group stocks the Ferritic steel nuts in Grades 2H, 2HM, 7, L7, and L7M which are normally used in conjunction with Grade B7, B7M, B16, L7 and L7M Bolt Shear Capacity. F A S T E N E R S.

L9 hex cap screws · L9 First, you need to be able to identify bolts by the different grades when you go to the So given a certain diameter (cross-sectional area) and strength rating,. Its strength grades are indicated by the letter A plus three numerals stamped on the bolt head. Common ASTM grades include A307, which roughly corresponds to SAE Grade 2. An ASTM A325 bolt is roughly equivalent in strength to SAE Grade 5 and an A490 bolt is about equivalent in strength to SAE Grade 8. US Bolts: Head Marking Grade and Material Nominal Size Range (inches) Mechanical Properties ; Proof Load (psi) Min. Yield Strength (psi) Min. Tensile Strength (psi) No Markings: Grade 2 Low or medium carbon steel: 1/4" thru 3/4" 55,000: 57,000: 74,000: Over 3/4" thru 1-1/2" 33,000: 36,000: 60,000: 3 Radial Lines: Grade 5 Medium carbon steel, quenched and tempered: 1/4" thru 1"
Metric bolt grades and strength calculator to show proof strength, tensile strength, Vickers / Brinell hardness, minimum breaking torque and stress area of metric bolts and screws made of carbon steel and alloy steel with designations 4.6, 4.8, 5.8, 8.8, 9.8, 10.9 and 12.9. A common question is whether stainless steel is stronger that a grade 5 or grade 8 bolt. Stainless commonly comes in grades 18.8 (304) or T316. 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). Replace a graded fastener with same or higher grade (don't replace a Grade 8 fastener with a Grade 5 or 2). If in doubt, ask a professional for assistance. The chart below summarizes some of the more common grades and classes available here at Fastener Mart .
Grade B7. ASTM A193 Grade B7 bolts and threaded studs are manufactured from a chromium-molybdenum steel and are quenched and tempered (heat treated) to develop the desired mechanical properties (strength). Grade B7 is the most common grade of A193 bolts used in construction. Metric bolt grades and strength calculator to show proof strength, tensile strength, Vickers / Brinell hardness, minimum breaking torque and stress area of metric bolts and screws made of carbon steel and alloy steel with designations 4.6, 4.8, 5.8, 8.8, 9.8, 10.9 and 12.9. A common question is whether stainless steel is stronger that a grade 5 or grade 8 bolt. Stainless commonly comes in grades 18.8 (304) or T316. 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). Replace a graded fastener with same or higher grade (don't replace a Grade 8 fastener with a Grade 5 or 2). If in doubt, ask a professional for assistance. The chart below summarizes some of the more common grades and classes available here at Fastener Mart . So, with a grade 8, this falls under the SAE J429. You can look that up to go over on google. Just google that and you'll find all the information in reference to the treatment of a grade 8 bolt. A grade 5 bolt falls under ASTM 574. A grade A325 falls under ASTM specifications also and you can look those up on google to get further information.
