Is Grade 8 the strongest bolt?
Grade 8 / Grade G Grade 8 bolts have been hardened more than grade 5 bolts.
Thus they are stronger and are used in demanding applications such as automotive suspensions.
Grade 8 bolts have 6 evenly spaced radial lines on the head..

What grade Bolt is the hardest?
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.
Are 18 8 and 304 the same?
304 stainless steel contains a minimum of 18% chromium and 8% nickel which gives its alternate name 18/8 stainless steel. 304 stainless steel contains chromium-nickel content and low carbon. This stainless steel type is oxidation and corrosion resistant.
Are titanium bolts stronger than steel?
Titanium bolts can be as strong as mild steel or stainless steel bolts. Titanium bolts are not as strong as high-tensile steel bolts.
What does Bolt grade 12.9 mean?
Grade 12.9 Bolt is a high tensile bolt that has a diameter of 12.9 mm and the lengths vary from 20mm to 200mm based on the application requirement. … There are studs, hex bolts, U bolts, T bolts and many other types in this grade.
Is stainless or Grade 8 stronger?
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 is the hardest bolt you can buy?
BUMAX® Ultra has proven itself as the world’s strongest bolt – in various highly-demanding critical fastener applications around the world where standard fasteners are simply inadequate.
What grade bolt has the highest shear strength?
They are commonly used at high stress points in connecting devices.12.9 Bolts. A 12.9 bolt is one of the highest grade of bolts produced. … 12.9 Shear Strength. The minimum tensile strength of a 12.9 bolt is 1220 MPa.
What is the difference between a 10.9 and 12.9 Bolt?
12.9 grade steel has 120% of the tensile strength of 10.9 grade steel. The “12” prefix indicates a tensile strength of X100 N/mm^2 and the “9” suffix indicates a multiplier. Both 12.9 and 10.9 have the same multiplier, so the comparison is straightforward: 12 to 10.
How hard is a 10.9 bolt?
Used in automotive applications and for bolting large and forged parts, metric 10.9 bolts exhibit high tensile strength and good wear resistance. Our metric grade 10.9 bolts meet ASTM A324 grade BD and SAE J429, grade 8 standards. The yield strength of the bolts is 940 and the tensile strength is 1040 MPa.
