Key Features & Benefits at a Glance
- Superior holding power with Class 3A thread fit for reliable, vibration-resistant fastening in demanding applications.
- Exceptional durability from Rockwell C45 hardened alloy steel, resisting wear and deformation under high stress.
- Corrosion-resistant black oxide finish extends service life by protecting against rust in various industrial environments.
- Secure and easy installation with a 1/4" hex drive, allowing for high torque application without slippage.
- Enhanced grip and positioning due to the extended tip design, which digs into the shaft for a more positive lock.
- Broad compatibility with 1/2"-13 UNC coarse threads, a common standard for robust assemblies.
- Regulatory peace of mind, compliant with RoHS 3 and REACH for safe and sustainable use.
Professional Applications & Engineering Value
This 1/2"-13 UNC set screw is engineered to solve critical challenges in power transmission and motion control systems. The headless, hex drive design allows for flush mounting in pulleys, gears, and collars, preventing interference in compact assemblies. Manufactured from black oxide alloy steel, it provides excellent resistance to corrosion and abrasion, which is vital in environments exposed to moisture, chemicals, or constant movement. The extended tip concentrates pressure on a smaller contact area, significantly increasing resistance to rotational forces and shaft slippage. This makes it an indispensable component for securing components on shafts in heavy machinery, automotive systems, and industrial equipment, ensuring operational integrity and reducing maintenance downtime.
Specification Summary & Compliance
This set screw features a 1/2"-13 UNC coarse thread with a precision Class 3A fit for superior thread engagement. The tip has a diameter of 0.343" (-0.009" to 0" tolerance) and a length of 0.13" (-0.005" to 0" tolerance). It is manufactured to meet ASME B18.3 specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
