Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments and chemical exposure.
- Exceptional thread precision with Class 3A fit for reliable, vibration-resistant assemblies and reduced risk of cross-threading.
- High-strength fastening provided by Rockwell B80 hardness, ensuring long-term durability under mechanical stress.
- Secure, non-slip installation enabled by the hex drive and 3/32" drive size, allowing for high torque application.
- Firm component gripping with a 90° cone point tip that digs into surfaces to prevent shifting or loosening.
- Broad industrial compatibility due to UNC coarse threading and right-hand direction, facilitating quick assembly.
- Regulatory peace of mind with compliance to ASME B18.3, RoHS 3, and REACH, ensuring safety and environmental standards.
Professional Applications & Engineering Value
This 10-24 UNC set screw is engineered to address critical challenges in precision machinery, automotive, and marine applications where vibration resistance and corrosion prevention are paramount. The 316 Stainless Steel material offers excellent performance in saline or acidic conditions, while the Class 3A thread fit ensures tight tolerances for secure fastening in dynamic loads. The hex headless design with a cone point allows for flush mounting and superior grip on shafts or collars, preventing axial movement. Ideal for securing gears, pulleys, and knobs, this screw provides reliable, long-term holding power where failure is not an option, reducing maintenance needs and enhancing operational safety.
Specification Summary & Compliance
This set screw adheres to ASME B18.3 specifications, with a Class 3A thread fit for high precision and a coarse UNC thread (10-24) for robust engagement. Dimensions include a 0.19" thread diameter and 1/4" length. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets strict environmental and health standards for industrial use.
