Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and outdoor applications.
- Exceptional mechanical strength offering 80,000 psi tensile strength and Rockwell B70 hardness for reliable, heavy-duty fastening.
- Efficient installation and removal facilitated by the external hex drive and standard right-hand coarse (UNC) threads.
- Optimized thread engagement with a partially threaded design and Class 2A fit, reducing the risk of cross-threading.
- Broad industrial compatibility ensured by compliance with the rigorous dimensional standards of ASME B18.2.1.
- Safe for sensitive applications as it meets RoHS 3 and REACH environmental regulations, containing no hazardous substances.
- Versatile 1-1/2" length provides ample grip for a wide range of material thicknesses in assembly projects.
Professional Applications & Engineering Value
This 5/16"-18 UNC hex head screw is engineered to address critical challenges in industrial assembly, such as vibration loosening and material fatigue. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it a durable choice for machinery, marine hardware, and food processing equipment exposed to moisture or chemicals. Its coarse thread design ensures faster installation and superior performance in softer materials or where debris is present. The combination of 80,000 psi tensile strength and a partially threaded shank concentrates clamping force precisely where needed, preventing joint failure and ensuring long-term structural integrity in demanding industrial fastening applications.
Specification Summary & Compliance
This screw features a 5/16"-18 UNC thread with a Class 2A thread fit for consistent, reliable engagement. It is manufactured in compliance with the ASME B18.2.1 standard, ensuring precise dimensional accuracy for hex head cap screws. The product is also verified to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, confirming its adherence to strict environmental and safety regulations for hazardous substances.
