S-92308A628 3/8"-16 x 1 1/2" ASME B18.6.2 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and extended service life.
• Exceptional torque transmission via the external square drive and square head, preventing tool slippage during high-torque installation.
• Reliable fastening strength backed by a Rockwell B80 hardness, ensuring the screw maintains its form under significant stress.
• Quick and easy installation with coarse UNC threads and Class 2A fit, facilitating faster assembly and reducing labor time.
• Secure and permanent positioning with the 1-1/2" length and cup point tip, designed to bite into surfaces for a non-slip hold.
• Guaranteed dimensional consistency and performance reliability through compliance with the ASME B18.6.2 standard.
• Safe for regulated industries as it meets RoHS 3 and REACH environmental compliance, ensuring no hazardous substances are used.

Professional Applications & Engineering Value

This square head set screw is engineered to solve critical challenges in industrial assembly and machinery. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it suitable for applications in moist or chemically aggressive environments, such as food processing equipment, marine hardware, and outdoor machinery. The external square drive and robust square head design allow for high torque application without cam-out, ensuring the screw is securely seated to lock components like gears, pulleys, and collars onto shafts. The coarse UNC thread and Class 2A fit offer a balance of quick assembly and reliable grip, reducing the risk of cross-threading in high-vibration settings. With its 1-1/2" length and cup point, it delivers deep engagement and resistance to loosening, providing long-term reliability in heavy-duty mechanical systems.

Specification Summary & Compliance

This set screw adheres to precise dimensional standards, including a Class 2A thread fit for consistent assembly and a 3/8"-16 UNC coarse thread profile. It is manufactured in compliance with the ASME B18.6.2 specification, ensuring mechanical integrity and interchangeability. The product also conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from restricted hazardous substances and safe for use in environmentally conscious industrial applications.
