Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments like marine or chemical processing.
- Enhanced durability and wear resistance from the black oxide finish, reducing maintenance and extending service life.
- Precise alignment and reduced wear on mating parts due to the 1/4" shoulder diameter and 1-3/8" shoulder length with tight tolerances.
- High-strength performance with 70,000 psi tensile strength and 35,000 psi shear strength, ensuring reliability in heavy-duty applications.
- Secure and precise fastening with Class 3A thread fit and UNC coarse threads, providing excellent grip and vibration resistance.
- Easy installation and removal using a standard 1/8" hex drive and knurled socket head, improving assembly efficiency.
- Compliance with industry standards including ASME B18.3, RoHS, and REACH, ensuring safety and regulatory acceptance.
Professional Applications & Engineering Value
This 10-24 UNC shoulder screw is engineered to address common industrial challenges such as misalignment, corrosion, and mechanical failure. Made from 316 stainless steel and finished with black oxide, it offers exceptional resistance to rust and chemicals, making it suitable for demanding environments like machinery, automotive assemblies, and outdoor equipment. The socket head design with hex drive allows for easy torque application in confined spaces, while the knurled texture enhances grip during manual adjustments. Its Class 3A thread fit and precise shoulder dimensions ensure stable rotational movement and reduced wear on components, providing long-term reliability and minimizing downtime in industrial applications.
Specification Summary & Compliance
This shoulder screw features a 10-24 UNC thread size with Class 3A thread fit for high precision, along with a shoulder diameter of 1/4" (tolerance: -0.004" to -0.002") and shoulder length of 1-3/8" (tolerance: -0.005" to 0.005"). It complies with ASME B18.3 specifications for dimensional accuracy and is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring adherence to environmental and safety regulations.
