Professional Applications & Engineering Value
This 3/4"-10 UNC shoulder screw is engineered to solve critical alignment and durability challenges in industrial machinery and precision equipment. The 316 Stainless Steel material, combined with a Black Oxide finish, provides outstanding resistance to corrosion, chemicals, and high-moisture environments, extending service life in demanding applications like automotive assemblies, food processing equipment, and marine hardware. The precisely machined 1" shoulder with controlled tolerances ensures accurate component positioning, reducing wear and misalignment in rotating parts or bearing mounts. With a Class 3A thread fit and coarse UNC thread, it offers secure fastening under vibration, while the knurled socket head allows for easy, slip-resistant installation with standard hex tools. This shoulder screw delivers reliable performance where precision, strength, and corrosion resistance are non-negotiable.
Specification Summary & Compliance
This shoulder screw features a 3/4"-10 UNC coarse thread with Class 3A fit for high-precision assembly. The shoulder diameter is 7/8" with a tolerance of -0.004" to -0.002", and the shoulder length is 1" with a tolerance of -0.005" to 0.005". 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 suitability for regulated industrial and international markets.
