Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel construction and Black Oxide finish, ideal for harsh industrial environments.
- Precise component alignment ensured by the 1/4" shoulder diameter and 3/8" shoulder length, reducing assembly errors.
- High-strength performance with 70,000 psi tensile strength and 35,000 psi minimum shear strength for reliable load-bearing applications.
- Secure, non-slip installation thanks to the knurled head and hex drive design, allowing for easy torque application.
- Accurate thread engagement with Class 3A thread fit and UNC coarse threading, providing consistent fastening in high-vibration settings.
- Compliance with industry standards including ASME B18.3, RoHS 3, and REACH, ensuring safety and regulatory adherence.
- Durable and long-lasting due to Rockwell B55 hardness, maintaining integrity under repetitive stress.
Professional Applications & Engineering Value
This 10-24 UNC thread shoulder screw is engineered to address critical alignment and durability challenges in industrial assemblies. Made from 18-8 Stainless Steel with a Black Oxide finish, it resists corrosion in moist or chemical-exposed settings, extending service life. The 3/8" shoulder length and precise 1/4" shoulder diameter provide a stable pivot or bearing surface, minimizing misalignment in machinery, automotive, and electronics applications. The socket head with hex drive allows for tight spaces and secure installation, while the Class 3A thread fit ensures reliable fastening under dynamic loads. Ideal for precision equipment, this screw enhances assembly efficiency and reduces maintenance needs.
Specification Summary & Compliance
This shoulder screw features a 10-24 UNC thread with Class 3A fit for high precision, and shoulder dimensions include a diameter of 1/4" (tolerance: -0.004" to -0.002") and length of 3/8" (tolerance: -0.005" to 0.005"). It complies with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use in global industrial markets.
