Key Features & Benefits at a Glance
- Superior holding power with Class 3A thread fit for precise, vibration-resistant fastening in demanding applications.
- Enhanced durability and corrosion resistance provided by the black-oxide finish on high-strength alloy steel.
- Reliable installation and removal ensured by the hex drive design, allowing for high torque application without slippage.
- Excellent material strength and wear resistance from the Rockwell C45 hardness, ensuring long service life.
- Secure and concentrated point contact with the cup tip design, preventing component slippage and damage.
- Optimized for fine-adjustment applications due to the UNF fine thread spacing, providing greater control in precision assemblies.
- Broad industry compatibility as a headless set screw, ideal for confined spaces where a low-profile fastener is required.
Professional Applications & Engineering Value
This 10-32 UNF Class 3A set screw is engineered to solve critical challenges in industrial assembly and machinery. Manufactured from black-oxide alloy steel, it offers exceptional resistance to corrosion and wear, making it suitable for harsh environments. The fine thread spacing and Class 3A thread fit provide superior clamping force and vibration resistance, essential for maintaining alignment in precision equipment like motor shafts, gears, and pulleys. The headless design with a hex drive allows for easy installation in tight spaces, while the cup tip ensures a firm grip on the secured component, preventing rotation and loosening under dynamic loads. Ideal for use in automotive, aerospace, and heavy machinery sectors, this set screw delivers reliable performance where failure is not an option.
Specification Summary & Compliance
This set screw features a 10-32 UNF thread with Class 3A fit for high precision and strength. It complies with ASME B18.3 specifications, ensuring dimensional accuracy and manufacturing consistency. The product is also RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety standards for hazardous substances.
