Professional Applications & Engineering Value
This 316 Stainless Steel Shoulder Screw is engineered to address critical challenges in precision assembly and machinery. The Class 3A thread fit and UNC coarse threads provide superior holding power and resistance to loosening under vibration, common in automotive, aerospace, and industrial equipment. The 1/4" shoulder acts as a precise pivot or spacer, ensuring accurate alignment of components like gears, bearings, and linkages, which reduces wear and maintenance. Made from corrosion-resistant 316 stainless steel, it performs reliably in moist or chemical-laden environments, extending equipment lifespan. The knurled socket head with a hex drive allows for high-torque installation without cam-out, making it a trusted choice for engineers seeking durability and precision in high-tensile strength applications.
Specification Summary & Compliance
This shoulder screw features a 10-24 UNC thread with Class 3A precision fit for tight tolerances, and a shoulder diameter of 1/4" with tolerances from -0.004" to -0.002". It is manufactured in compliance with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring it is free from hazardous substances and suitable for global industrial use.
