Professional Applications & Engineering Value
This 10-32 UNF thread shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, making it suitable for machinery, automotive, and electronic applications exposed to moisture or chemicals. The black oxide finish not only enhances aesthetics but also reduces galling and wear during repeated use. With a fine thread and Class 3A thread fit, it ensures tight tolerances and minimizes loosening under vibration, while the 1/4" shoulder length offers precise positioning for rotating parts like bearings and pulleys. This design maximizes operational reliability and reduces maintenance needs in industrial shoulder bolt applications.
Specification Summary & Compliance
This shoulder screw features a 10-32 UNF thread with Class 3A fit for high precision, a shoulder diameter of 1/4" with tight tolerances (-0.004" to -0.002"), and a shoulder length of 3/8" controlled within -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 safety and reliability for global industrial use.
