Professional Applications & Engineering Value

This 3/4"-10 UNC shoulder screw is engineered to address common industrial challenges, such as misalignment and component wear in machinery. The 18-8 stainless steel material provides excellent corrosion resistance, reducing maintenance in humid or chemical-exposed settings. With a coarse UNC thread and right-hand direction, it ensures quick assembly and disassembly, while the hex socket drive and knurled head enhance torque application without slippage. Ideal for precision applications like industrial automation, conveyor systems, and pivoting mechanisms, the screw's high tensile and shear strength supports heavy-duty operations, minimizing downtime and extending equipment life.

Specification Summary & Compliance

This shoulder screw features a Class 2A thread fit with UNC coarse threads for reliable engagement. Dimensions include a shoulder diameter of 3/4" (tolerance: -0.004" to -0.002") and shoulder length of 1-3/4" (tolerance: -0.005" to 0.005"), ensuring precise fits. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free of hazardous substances and suitable for regulated industries.
