GB 899 bm=1.5d Double End Studs: Precision Fasteners for Industrial Applications

When strength, accuracy, and stability are crucial in mechanical assemblies, GB 899 bm=1.5d double end studs emerge as a trusted fastening solution. These precision-engineered studs follow the GB 899 standard, with a bm=1.5d specification that ensures optimal thread engagement and reliable performance in a wide range of industrial applications.

If you're sourcing high-quality fasteners, understanding the function and benefits of GB 899 bm=1.5d double end studs is essential.

? What Are GB 899 bm=1.5d Double End Studs?

GB 899 bm=1.5d double end studs are threaded rods with equal threads on both ends and an unthreaded center shank. Designed according to the GB 899 Chinese national standard, the bm=1.5d refers to the thread length on one end being 1.5 times the diameter (d) of the stud. These studs are commonly used in machinery, automotive, construction, and tooling systems where high axial load and repeatable precision are required.

? Understanding the bm=1.5d Specification

The bm=1.5d in GB 899 bm=1.5d double end studs indicates that one threaded portion is 1.5 times the nominal diameter of the stud. For example, a stud with a 10mm diameter will have a 15mm thread length on the specified side.

This proportion offers several advantages:

• Optimal thread engagement

• Reliable load distribution

• Reduced stress concentration

The GB 899 bm=1.5d double end studs are ideal for connecting parts that require balanced torque and tension.

? Key Features of GB 899 bm=1.5d Double End Studs
