Key Features & Benefits at a Glance
- Exceptional holding power with UNC coarse threads and Class 2A fit for reliable, vibration-resistant fastening in demanding applications.
- Superior torque transmission from the external square head design, allowing for easy installation and removal with standard tools.
- Enhanced grip and resistance to loosening provided by the cup point tip, which bites into the mating surface for a secure, semi-permanent lock.
- Robust durability and strength from the steel construction and Rockwell B80 hardness, ensuring long-term performance under stress.
- Broad industrial compatibility with the 1/4"-20 thread size and 1 1/2" length, making it a versatile component for various assemblies.
- Guaranteed quality and reliability as it meets the stringent dimensional and mechanical specifications of the ASME B18.6.2 standard.
- Safe for use in regulated environments with full compliance to RoHS 3 and REACH environmental directives.
Professional Applications & Engineering Value
This 1/4"-20 UNC steel set screw is engineered to solve critical challenges in industrial assembly, such as component slippage and vibration-induced loosening. The square head and external drive style provide excellent torque application, reducing the risk of tool slippage during installation. The cup point tip concentrates pressure to create a deep indentation in the shaft or component, offering a powerful mechanical lock that is ideal for securing pulleys, gears, and collars on rotating machinery. Made from high-strength steel and heat-treated to a Rockwell B80 hardness, it withstands high shear and tensile forces, ensuring the integrity of your assembly in heavy-duty applications like automotive, manufacturing, and agricultural equipment.
Specification Summary & Compliance
This set screw features a 1/4"-20 UNC coarse thread with a Class 2A thread fit for standard tolerance and easy assembly. It is manufactured in compliance with the ASME B18.6.2 standard, ensuring consistent dimensional accuracy and performance. The product is also confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting current environmental regulations for hazardous substances.
