Key Features & Benefits at a Glance
- Superior corrosion resistance with black-oxide coating, extending service life in demanding industrial environments.
- Exceptional holding power provided by the Class 3A thread fit, ensuring a tight, secure, and vibration-resistant connection.
- High-strength durability from Rockwell C45 hardened alloy steel, resisting wear and deformation under heavy loads.
- Easy and secure installation with the 0.035" hex drive, allowing for high torque application without slippage in confined spaces.
- Reliable component positioning thanks to the cup tip design, which bites into surfaces for a non-slip, permanent assembly.
- Broad compatibility with the 2-56 UNC coarse thread, making it ideal for a wide range of standard industrial components and assemblies.
- Confident global sourcing ensured by compliance with RoHS 3 and REACH environmental regulations.
Professional Applications & Engineering Value
This black-oxide alloy steel set screw is engineered to solve critical challenges in precision assembly and machinery. The headless design and hex drive allow for flush mounting in tight spaces where protrusions are not permissible. Its Rockwell C45 hardness and Class 3A thread fit provide a robust, vibration-resistant fastening solution, preventing loosening in dynamic applications such as motor shafts, gears, and pulleys. The 2-56 UNC coarse thread ensures quick assembly and high tensile strength, while the cup tip offers superior grip on the contact surface, making it an indispensable heavy-duty fastener for automotive, aerospace, and industrial equipment manufacturing where reliability is non-negotiable.
Specification Summary & Compliance
This set screw features a 2-56 UNC coarse thread with a precise Class 3A thread fit for superior dimensional accuracy. It is manufactured in compliance with the ASME B18.3 standard, ensuring consistent quality and performance. The product is also verified to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent international environmental and safety regulations for industrial use.
