Key Features & Benefits at a Glance
- Exceptional corrosion resistance from 18-8 stainless steel construction, ideal for harsh industrial environments.
- Enhanced durability and wear resistance with a black oxide finish that reduces galling and provides a sleek appearance.
- Superior load-bearing capacity with 70,000 psi tensile strength and 35,000 psi minimum shear strength for reliable performance under stress.
- Precise alignment and secure fit thanks to the Class 3A thread fit and standard shoulder, minimizing assembly play.
- Easy installation and removal with a knurled socket head and 1/8" hex drive, reducing tool slippage.
- Broad compatibility with 10-24 UNC coarse threads, ensuring quick fastening in various materials.
- Long-term operational reliability backed by Rockwell B55 hardness, resisting deformation in repetitive use.
Professional Applications & Engineering Value
This 18-8 stainless steel shoulder screw is engineered to address common industrial challenges such as misalignment, corrosion, and mechanical failure. The black oxide finish not only enhances aesthetics but also provides a protective layer against oxidation and friction, extending service life in demanding settings like machinery, automotive assemblies, and precision equipment. Its 10-24 UNC coarse thread and 3/8" shoulder length ensure rapid, secure fastening while the socket head with hex drive allows for efficient torque application in confined spaces. By combining high tensile and shear strength, it reduces downtime and maintenance costs, making it a trusted component for industrial applications requiring robust, compliant fasteners.
Specification Summary & Compliance
This shoulder screw adheres to Class 3A thread fit for precise tolerances and is manufactured in compliance with ASME B18.3 standards. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety adherence. Dimensions include a shoulder diameter of 1/4" with a tolerance of -0.004" to -0.002" and shoulder length of 1 1/2" with -0.005" to 0.005" tolerance, guaranteeing consistent performance in precision shoulder bolt applications.
