Professional Applications & Engineering Value
This precision shoulder screw delivers exceptional engineering value in applications requiring exact component positioning and rotational stability. The 18-8 stainless steel construction provides excellent corrosion resistance while maintaining Rockwell B55 hardness for durability in mechanical assemblies. The 1" shoulder length serves as a precise datum for mounting gears, pulleys, and linkages, eliminating the need for additional spacers. The knurled socket head with 1/8" hex drive ensures secure tool engagement, preventing cam-out during high-torque applications. With Class 3A thread fit and coarse UNC threading, this shoulder screw offers reliable performance in automated equipment, precision machinery, and industrial assemblies where vibration resistance and repeated maintenance are critical factors.
Specification Summary & Compliance
This shoulder screw features precision 5/16"-18 UNC coarse threads with Class 3A fit for superior thread engagement. The shoulder diameter maintains tight tolerance of -0.004" to -0.002" with shoulder length tolerance of -0.005" to 0.005" ensuring consistent dimensional accuracy. Manufactured to meet RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations, this component is suitable for global industrial applications requiring environmental responsibility and material safety standards.
