Professional Applications & Engineering Value

This 5/8"-11 UNC shoulder screw is engineered to address critical alignment and pivot point requirements in demanding machinery. The 18-8 Stainless Steel material provides inherent corrosion resistance, making it suitable for applications exposed to moisture, chemicals, or outdoor elements, such as conveyor systems, packaging equipment, and automotive assemblies. The knurled hex socket head ensures secure tool engagement, preventing slippage during high-torque installations and reducing operator fatigue. With a 5/8" shoulder diameter and 3/4" thread length, it offers precise component positioning and rotational control, minimizing wear on mating parts. Ideal for use in industrial shoulder bolts applications like rotating shafts, pulleys, and levers, this screw delivers consistent performance, reduces downtime, and extends equipment life in heavy-duty environments.

Specification Summary & Compliance

This shoulder screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent dimensional accuracy. The shoulder diameter is maintained at 5/8" 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", ensuring precise fit in assemblies. Manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, it is free from hazardous substances, supporting safe and sustainable industrial use.
