• High load-bearing capacity with 70,000 psi tensile strength and Rockwell B55 hardness for reliable performance under stress.
• Precise alignment and smooth rotation ensured by the 1/4" shoulder diameter with tight tolerance and smooth texture.
• Accurate and secure threading with Class 2A fit and 10-32 UNF fine thread, reducing the risk of cross-threading and loosening.
• Versatile drive options with combined Socket and Slotted head styles for flexible installation using common tools.
• Regulatory compliance with RoHS 3 and REACH standards, ensuring safety and environmental responsibility in global markets.

Professional Applications & Engineering Value

This 10-32 UNF shoulder screw is engineered to address common industrial challenges such as misalignment, vibration-induced loosening, and corrosion. The 18-8 Stainless Steel construction offers excellent durability against moisture and chemicals, while the Nylon Patch thread locker provides reliable locking without requiring additional adhesives. The fine thread and Class 2A fit ensure precise engagement in assemblies like machinery linkages, conveyor systems, and precision instruments, where the 1 1/2" shoulder length acts as a pivot or spacer. Its ability to maintain integrity across a wide temperature range makes it suitable for automotive, aerospace, and food processing equipment, enhancing operational reliability and reducing maintenance needs.

Specification Summary & Compliance

The screw features a Class 2A thread fit with UNF fine threading (10-32 size) for consistent accuracy, and a shoulder diameter of 1/4" with tolerances from -0.001" to 0" for precise fits. Manufacturing adheres to standard inch measurements, with a tensile strength of 70,000 psi and hardness of Rockwell B55. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets strict environmental and safety standards for industrial use.
