Rust Proof Hexagon Head Bolt Chrome Plating Surface Treatment Long Life Span

AMSE Hexagon head bolts,Half thread,Carbon Steel,With Black Surface Treatment

1. Product Description

ASME Grade 5 Black Heat Treatment Half Thread Shackle Bolt Hex Bolt with Knurls​ are widely used in America. We have great quality and prodece strictly as the drawing and the standard.

9/16" x 3" steel shackle bolt with nut and installed zerk fitting. Knurls prevents the bolt from turning, which can wear hanger brackets and zerk fitting allows you to easily grease your spring hangers and equalizers. Grade 5 steel. Sold as each.

The equivalent metric standard is ASTM A325M, which is titled Standard Specification for Structural Bolts, Steel, Heat Treated 830 MPa Minimum Tensile Strength. It defines mechanical properties for sizes M12–36. There is also a T version, which is used to refer to fully threaded bolts.

heavy hex structural bolts is a kind of high strength bolts, which is standard parts also. Securing better performance for the steel, engineering, fastening effect. General steel, steel bolts are required more than 8.8, there are 10.9, 12.9, and steel are all high strength bolts.
