Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments.
- Exceptional holding power provided by the Class 3A thread fit, ensuring reliable, vibration-resistant fastening.
- High-strength durability from Rockwell B80 hardness, resisting wear and deformation under load.
- Precise, secure engagement with fine UNF thread spacing, minimizing the risk of loosening in critical assemblies.
- Easy installation and removal using the 5/32" hex socket drive, allowing for high torque application in confined spaces.
- Effective component positioning with the 90° cone point, which bites into surfaces for positive location and alignment.
- Broad industry compliance meeting ASME B18.3 standards, ensuring dimensional accuracy and interchangeability.
Professional Applications & Engineering Value
This 5/16"-24 UNF set screw is engineered to solve common industrial fastening challenges, such as shaft collars, gears, and pulleys slipping under torque and vibration. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for applications in moist or chemically aggressive environments, including food processing, marine, and outdoor machinery. The fine thread spacing and Class 3A fit offer tighter tolerances than standard fits, which is critical for maintaining precise alignment in high-precision equipment. The headless design and hex socket drive allow for flush mounting and easy access in tight spaces, reducing assembly time and improving the aesthetic finish of the final product. This combination of features ensures reliable performance in demanding industrial applications, from automotive to aerospace assemblies.
Specification Summary & Compliance
This set screw adheres to Class 3A thread fit for high precision and UNF thread type with a 5/16"-24 fine thread specification. It is manufactured in compliance with ASME B18.3 standards, ensuring dimensional accuracy and performance reliability. Additionally, the product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, confirming it meets stringent environmental and safety regulations for hazardous substances.
