- Maximum grip and minimal slippage due to the cup point design, ensuring secure component positioning.
- High-strength durability from alloy steel with Rockwell C45 hardness, resisting wear under heavy loads.
- Easy installation and removal with a 1/8" hex drive, allowing efficient maintenance in tight spaces.
- Reliable performance compliance meeting MS51964-64 specifications for consistent quality in demanding applications.
- Space-saving headless design ideal for flush-mount applications where protrusion is not feasible.
Professional Applications & Engineering Value
This 1/4"-28 UNF Class 3A cup point set screw is engineered to address common industrial challenges such as component loosening due to vibration and misalignment. Crafted from cadmium-plated alloy steel, it offers excellent corrosion protection, making it suitable for outdoor machinery, automotive systems, and precision equipment. The fine thread configuration and cup point tip provide deep biting action into shafts and collars, ensuring permanent positioning without frequent retightening. Its headless design and hex drive facilitate easy installation in confined areas, reducing assembly time and enhancing operational reliability in industrial set screw applications.
Specification Summary & Compliance
This set screw adheres to Class 3A thread fit for high precision and tight tolerances, with UNF fine threads (1/4"-28) and right-hand direction. It meets MS51964-64 specifications for dimensional accuracy and performance, ensuring compatibility with standard industrial components. The cadmium plating provides RoHS and REACH compliance for environmental safety, while the material and hardness (Rockwell C45) align with common industry standards for durability and load-bearing capacity.
