Machine Shackle high strength stainless bolts with Knurls under Hex Head
 

 Description:

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

We can produce as customers drawing. And the material is 45#, 35# with heat treatment. 

Hexagon Bolts are a class of fasteners consisting of a head and a screw (with an external thread) are fitted with a nut for fastening the connection of two parts with through holes.

The ASTM thread, inch, is known as the Unified system, this measurement system is primarily used in the USA. It uses feet, inches and fractional inches as its basic measurements.

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.
