Nuts and bolts are the glue that hold together our mechanical contraptions. These simple devices are one of the most important inventions of the mechanical age. The 12.9 bolt is a higher tensile bolt made from alloy steel that is quenched and tempered. They are commonly used at high stress points in connecting devices. 4140 Alloy Steel T-Bolt, Black Oxide Finish, Square Head Also known as tugger bolts, the table size and thread size are the same. Material is 4140 steel, comparable to grade 8. Workholding components. Clamping components. Measures 2" thread length by 5-5/16" overall length.

AISI4140 cold drawn steel bar; CD 4140 / 4142 alloy bar's chromium content provides good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength. Difference Between Alloy Steel and Stainless Steel The main difference between carbon steel and stainless steel is the amount of chromium that is added to the alloy. While the amount of chromium in carbon steel is usually negligible, stainless steel has 10-20% chromium, and may have 7-9% of nickel.
Also known as chrome-moly steel, 4140 alloy steel resists fracturing from repeated stress. Multipurpose 4140 Alloy Steel Bars Also known as chrome-moly steel, this versatile 4140 alloy steel is used for a wide range of parts, such as gears, axles, shafts, collets, and die holders. Grade 8 alloy Steel? - Practical MachinistDec 06, 2011 · Grade 8 basically just says they want a minimum strength, and could really care less about the material. It is kind of a stupid way of putting it. "alloy steel, 150ski minimum tensile strength" would have been a better way to put it, unless the bolt can actually made by modifying an off the Steel Bolts McMaster-CarrChoose from our selection of steel bolts, including over 650 products in a wide range of styles and sizes.
