- Precise component alignment ensured by the 3/8" shoulder length and standard shoulder fit, reducing assembly time and improving machine accuracy.
- High-strength performance with 70,000 psi tensile strength and 35,000 psi minimum shear strength for reliable operation under significant loads.
- Secure, slip-resistant fastening provided by the knurled socket head and 1/8" hex drive, allowing for high-torque installation without tool slippage.
- Consistent, reliable threading with Class 3A fit and 10-24 UNC coarse thread, enabling quick assembly and strong holding power.
- Broad industry compliance meeting ASME B18.3 specifications, RoHS 3, and REACH regulations for safe, global use in regulated sectors.
- Enhanced durability from Rockwell B55 hardness, resisting wear and deformation in high-cycle applications.
Professional Applications & Engineering Value
This 18-8 Stainless Steel Shoulder Screw is engineered to solve critical alignment and pivot point challenges in precision machinery. The 3/8" shoulder length acts as a precise datum for locating parts like gears, bearings, and linkages, eliminating misalignment and reducing wear. Its 10-24 UNC coarse thread and Class 3A fit ensure rapid, secure fastening in assemblies requiring repeated disassembly. The knurled socket head with a hex drive provides excellent grip for high-torque applications, preventing cam-out in confined spaces. Made from corrosion-resistant 18-8 stainless steel, it withstands demanding environments in automation, aerospace, and medical equipment, delivering long-term reliability and reduced maintenance.
Specification Summary & Compliance
This shoulder screw features a 10-24 UNC thread with a Class 3A fit for high precision. The shoulder diameter is 1/4" with a tolerance of -0.004" to -0.002", and the shoulder length is 3/8" with a tolerance of -0.005" to 0.005". It is manufactured to ASME B18.3 standards and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material quality for industrial use.
