Key Features & Benefits at a Glance
- Superior corrosion resistance from 18-8 stainless steel construction, ensuring long-term reliability in harsh or humid environments.
- Exceptional holding power with Class 3A thread fit, providing tighter tolerances and more secure fastening than standard classes.
- High-strength performance backed by Rockwell B80 hardness, offering excellent resistance to wear and deformation under load.
- Secure, flush installation due to the headless hex drive design, allowing for a clean finish and preventing snagging.
- Enhanced grip and minimal surface damage from the cup tip, which concentrates force for reliable positioning of components.
- Precision-engineered fine threads (UNF) for improved adjustment accuracy and vibration resistance in critical assemblies.
- Broad regulatory compliance including RoHS 3 and REACH, ensuring safety and environmental standards are met for global supply chains.
Professional Applications & Engineering Value
This 3/8"-24 UNF hex headless set screw is engineered to address common industrial challenges such as component slippage, vibration-induced loosening, and corrosion in demanding settings. Manufactured from 18-8 stainless steel, it provides excellent resistance to oxidation and chemical exposure, making it ideal for use in machinery, automotive systems, and marine equipment. The Class 3A thread fit and fine thread spacing ensure a precise, tight engagement that maintains clamping force even under dynamic loads. The cup tip design minimizes damage to shaft surfaces while providing a firm grip, and the headless hex drive allows for unobtrusive installation in space-constrained applications. Compliant with ASME B18.3, this set screw delivers consistent performance for alignment, locking, and positioning tasks where reliability is critical.
Specification Summary & Compliance
This set screw features a 3/8"-24 UNF thread with Class 3A precision fit and fine thread spacing, ensuring high dimensional accuracy and secure fastening. It is manufactured in accordance with ASME B18.3 specifications and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to environmental and safety standards for industrial use.
