#8 Rebar . Composed of a sturdy carbon steel composite, #8 rebar is a high-grade reinforcement product trusted for medium or heavy commercial applications. #8 reinforcement steel is known as 25MM in the metric system. Project uses for this large-diameter rebar includes:Footings; Piers; Columns and beams; Caissons; Shear walls; High-rise transfer slabs Bolt Depot - Selecting Fastener Materials - Steel Grades 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. Grade G is roughly equivalent to Grade 8. Grade G nuts are used with Grade 8 bolts. Alloy Steel
A grade 8 bolt is stronger than the more commonly used grade 5. It is made of alloy steel and has six radial lines on the top of the bolt head. Grade 8 bolts have a tensile strength of 150,000 pounds per square inch. We recommend using grade 8 nuts, flat washers and high alloy lock washers with any grade 8 bolts / hex cap screws. Grade 8 Steel Screws - Grainger Industrial SupplyGrade 8 Steel Screws. 2 products. Screws are threaded fasteners that create permanent or temporary assemblies. They are inserted and removed by turning in one direction or another. Wood screws, floor screws, and sheet metal screws have flat heads that sit flush when holding material together. Machine screws fasten metal to metal and are inserted into a prethreaded
This grade is part of the SAE classification; it is the minimum standard of the automotive and structural industries, plus it is used in high-temperature applications. Grade 8 is near the high end of the grade scale, although there are higher grades and strengths for more specialized fasteners. Grades of Bolts - The Home DepotThe 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 the number means the stronger the bolt. For most home and automotive applications, you wont need anything more than a grade 8 bolt strength or metric class 10.9.
Our Alloy Steel Grade 8.8 Studs are delivered to a lot many industries as they find usage in a wide range of applications. We produce these Grade 8.8 Bolts in a way that they provide good tensile strength and provide good performance in different environments. Metric Grade 8.8 Bolts U-Bolt-It, Inc.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. They do not perform well in environments that experience temperature extremes.

SAE Grade 8 Screws are marked on the top of their heads, the exceptions being small (under about 1/4"), slotted and recessed head fasteners where there is insufficient room for head markings. A head with no markings is Grade 2, one with 3 lines spaced 120 degrees is Grade 5, and 6 lines spaced at 60 degree intervals is Grade 8. Welding Grade 5 Or 8 Bolts - Miller Welding Discussion 05-05-2006, 06:26 PM. If these bolts are the ones I think they are---I wouldn't risk it. Grade 8 bolts are a medium carbon, alloy steel that has been quenched and tempered---so heat will cause a change in the physical properties.
Grade 8 bolts are a medium carbon, alloy steel that has been quenched and tempered---so heat will cause a change in the physical properties. What Is the Difference Between Plain Grade 8 Bolt & Yellow Grade 8 Steel Bolts According to K-T Bolt Manufacturing Inc., Grade 8 bolts "are used in demanding applications such as automotive suspensions. 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.
Feb 23, 2018 · Grade 8 specs serve the fastener industry where shear, fatigue, bending, and stress reversal are not factors. If the customer wishes this for an application requiring unusual resistance to shock or fatigue he should provide better material specs than "Grade 8.".ASTM A194 Grade 8 Specification - Boltport Fasteners39 rows · Grade 8 Standard Specification for Carbon and Alloy Steel Nuts for Bolts for High
