Grade 8 steel threaded rods are about 25% stronger than medium-strength steel rods. Zinc yellow - chromate plated steel threaded rods resist corrosion in wet environments. Black - oxide steel threaded rods have a dark surface color and are corrosion resistant in dry environments.
The stronger and more heat resistant Grade 5 threaded rod is made of medium carbon steel quenched and tempered. It is classified as ASTM A449. ASTM A354 is the classification for Grade 8 threaded rod, made of high-strength steel quenched and tempered.
Metric Grade 8.8 Bolts. Grade 8.8 Bolts are manufactured using medium carbon steel that has been quenched and tempered. Used in railroad equipment, motors, engines and processing equipment, grade 8.8 bolts exhibit good tensile strength and perform well in most environments.
Q & T - Quenched and Tempered. Although markings are shown on hex heads, stamping is a requirement on one end of rods and studs. The exception is F1554 and A307 grade C in which stamping is a supplemental requirement while color coding is required. Although markings are shown on
What is 8.8 grade steel and what is it used for? - Quora
Jul 04, 2016 · Grade 8.8 Bolts are manufactured by Structural Steel Supplier in Singapore using medium carbon steel that has been quenched and tempered. Grade 8.8 high tensile steel is often referred to as the structural grade for bolts. Grade 8.8 bolts exhibit good

Grade 8 is a medium carbon or alloy steel, and has one of the highest tensile strengths available, even higher than B7. It is also quenched and tempered at 800 F leading to its strength. The preload, or thread tension in a fastener is higher when the type of steel being used is grade 8 in quality.
High-Strength Gr. 8.8 Gr.10.9, Gr.12.9 ASTM A325,A490
High-Strength Gr. 8.8 Gr.10.9, Gr.12.9 ASTM A325,A490 Heavy Hex Bolt. Heavy hex structural bolts are designed for steel-to-steel structural connections. Consequently, they are typically very short. The A325 and A490 specifications are not intended for general applications, including anchor bolts.
Carbon steel grade 8.8 threaded screw, carbon steel material color, American standard B7 material, legs connecting parts usually installed under finger rack, general change teeth set in other parts, also used in construction and decoration, the length of teeth should be appropriate to expose nut 1-2 spacing after tightening, stainless steel material 304316,.
EN8 steel grade belongs to the standard of BS 970-1955, which is a standard for wrought steel for mechanical and allied engineering purpose. In BS 970 standards, there are some other common steel grades, like EN9, EN19, EN24, EN36 etc. And the most equivalent is
* Zero-cleaning with SAFEsetTM technology with the Hilti HIT-Z anchor rod is currently for use at a base material temperature above 41 °F (+5 °C). For use below 41 °F (+5 °C) and for full installation procedures refer to the product instructions for use on the product packaging or contact Hilti. 3/8-in. to 5/8-in.
Strength Requirements by Grades. Yield strength, or working load limit, is the amount of stress a material can withstand without permanent deformation.. Tensile strength is the maximum amount of axial stress that a material can take before breaking.. All strength measurements are in ksi (kilo-pound per square inch). To find the actual weight a bolt can withstand you would have to multiply by
