Professional Applications & Engineering Value

Engineered for demanding industrial applications, these flanged rounded head screws combine the corrosion resistance of 18-8 stainless steel with the mechanical reliability of 70,000 PSI tensile strength. The passivated finish provides an additional protective layer against chemical exposure and atmospheric corrosion, making them ideal for marine, chemical processing, and outdoor equipment applications. The integrated flange design distributes clamping force evenly, preventing surface damage while eliminating the cost and complexity of separate washers. With 10-24 UNC coarse threading and Class 3A thread fit, these screws deliver superior engagement in both metallic and non-metallic materials, reducing installation time while maintaining vibration resistance in high-stress environments.

Specification Summary & Compliance

This 1-1/2" flanged rounded head screw features precision 10-24 UNC coarse threading with Class 3A thread fit for exceptional dimensional accuracy. The inch system fasteners maintain Rockwell B70 hardness and 70,000 PSI tensile strength throughout their service life. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets. The partial threading with 7/8" minimum thread length provides optimal performance in various assembly configurations while maintaining structural integrity.
