• High-strength durability provided by a Rockwell B80 hardness, resisting wear and deformation under load.
• Secure, flush installation with a headless and cup tip design, preventing component interference and providing excellent torque transmission.
• Reliable, standardized performance as it meets ASME B18.3 specifications, guaranteeing consistent quality and interchangeability.
• Easy installation and removal with a 0.050" hex drive and right-hand coarse (UNC) threads, simplifying maintenance and assembly processes.
• Safe for regulated industries with full compliance to RoHS 3 and REACH, ensuring environmental and safety standards are met.

Professional Applications & Engineering Value

This 3-48 UNC set screw is engineered to solve critical challenges in precision machinery and industrial equipment. The 18-8 stainless steel material offers excellent resistance to rust and corrosion, which is vital for applications in volatile or outdoor settings. Its headless design with a hex drive allows for a flush fit, eliminating protrusions that could interfere with moving parts or require additional space. The Class 3A thread fit and coarse thread spacing provide a tighter tolerance, reducing the risk of loosening under vibration—common in motors, gears, and shaft collars. Combined with the cup tip, it bites securely into surfaces, distributing force evenly to prevent damage and ensure long-term reliability. This makes it an indispensable industrial fastener for OEMs and maintenance teams seeking durability and precision.

Specification Summary & Compliance

This set screw adheres to a Class 3A thread fit for high precision in inch measurements, with UNC coarse threads (3-48 size) and a thread diameter of 0.099". It is manufactured in compliance with ASME B18.3 standards and is fully RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring it meets stringent environmental and safety regulations for industrial use.
