Professional Applications & Engineering Value
This alloy steel shoulder screw is engineered to address critical alignment and strength requirements in industrial applications such as machinery assemblies, pivoting mechanisms, and precision equipment. The 3/4"-16 UNF fine thread with Class 3A fit ensures minimal backlash and reliable clamping force, reducing the risk of loosening under vibration. The 4" shoulder length and 1" shoulder diameter provide a stable bearing surface, facilitating accurate component positioning and minimizing misalignment issues. Combined with the black oxide finish, it offers enhanced corrosion resistance, making it ideal for harsh operational environments. Its high tensile strength and Rockwell C32 hardness ensure long-term performance, reducing maintenance needs and downtime in heavy-duty applications.
Specification Summary & Compliance
This shoulder screw features a 3/4"-16 UNF thread with Class 3A precision tolerance for secure fastening. The shoulder diameter is 1" with a tolerance of -0.004" to -0.002", and the shoulder length is 4" with a tolerance of -0.005" to 0.005", ensuring consistent fit and alignment. Manufactured from alloy steel with a black oxide finish, it complies with RoHS 3 (2015/863/EU) under exemption 6(a) and REACH (EC 1907/2006) standards, confirming its suitability for regulated industrial use.
