Key Features & Benefits at a Glance
- Exceptional holding power with Class 3A thread fit for secure, vibration-resistant fastening in demanding applications.
- Superior strength and durability from Alloy Steel heat-treated to Rockwell C45 hardness, resisting wear and deformation.
- Corrosion-resistant Black Oxide finish provides a protective layer, extending service life in various industrial environments.
- Easy and secure installation with a 1/4" Hex Drive, allowing for high torque application without slippage.
- Enhanced gripping capability due to the Extended Tip design, which bites into the mating part for a more positive lock.
- Reliable coarse (UNC) thread ensures quick assembly and disassembly, even in dirty or debris-filled environments.
- Guaranteed compliance and safety by meeting ASME B18.3 specifications and being RoHS 3 and REACH compliant.
Professional Applications & Engineering Value
This 1/2"-13 UNC Set Screw is engineered to solve critical challenges in industrial assembly and machinery. The Black Oxide Alloy Steel construction, combined with a Rockwell C45 hardness, provides the necessary toughness to prevent stripping and withstand high shear forces, making it ideal for securing gears, pulleys, and collars on shafts. The headless design and extended tip allow for flush mounting and create a deeper indentation in the shaft, effectively resisting loosening under severe vibration—a common failure point in rotating equipment. Its coarse UNC thread and Class 3A fit ensure a precise, tight engagement, offering a reliable solution for maintenance and OEM applications where disassembly is required.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including a Class 3A thread fit for superior tolerance and a coarse UNC thread form (1/2"-13). Manufacturing and quality are governed by the ASME B18.3 specification. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances for safe use in global markets.
