Professional Applications & Engineering Value
This 10-32 UNF shoulder screw is engineered from alloy steel to address critical industrial needs for precision and reliability. The Black Oxide finish provides enhanced corrosion resistance, extending service life in demanding applications like machinery assembly, automotive systems, and precision instruments. Its Class 3A thread fit and fine UNF threads deliver superior vibration resistance, minimizing loosening in dynamic environments. The knurled socket head with hex drive ensures secure, efficient installation, while the precisely machined shoulder (1/4" diameter) facilitates accurate component alignment, reducing wear and maintenance costs. Ideal for industrial shoulder screw applications requiring high strength and dimensional stability.
Specification Summary & Compliance
This shoulder screw adheres to Class 3A thread fit standards with UNF fine threads, ensuring tight tolerances for reliable performance. Dimensions include a shoulder diameter of 1/4" (tolerance: -0.004" to -0.002") and shoulder length of 1/4" (tolerance: -0.005" to 0.005"). Manufactured from alloy steel with a tensile strength of 140,000 psi and Rockwell C32 hardness, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance for environmental and safety regulations.
