Professional Applications & Engineering Value
This 10-24 UNC shoulder screw is engineered to address common industrial challenges such as misalignment, wear, and corrosion. The 17-4 PH Stainless Steel construction provides excellent durability and resistance to oxidation, making it suitable for demanding environments like machinery, automotive, and aerospace. The Class 3A thread fit and precise shoulder diameter ensure minimal play and reliable positioning in assemblies involving gears, pulleys, or linkages. With a knurled socket head and hex drive, it allows for secure tightening even in confined spaces, reducing the risk of stripping and enhancing maintenance efficiency. Its high tensile and shear strength supports heavy-duty applications, offering long-term reliability and reduced downtime.
Specification Summary & Compliance
This shoulder screw features a 10-24 UNC thread with Class 3A fit, ensuring high precision and interchangeability. The shoulder diameter is 1/4" 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". It meets ASME B18.3 specifications for dimensional accuracy and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental responsibility.
