Professional Applications & Engineering Value

Engineered for demanding industrial applications, these 18-8 stainless steel rounded head screws deliver exceptional performance where corrosion resistance and mechanical reliability are critical. The passivated finish significantly enhances surface protection against chemical exposure and oxidation, while the UNC coarse threading ensures rapid installation in various materials without stripping. The binding head design with wide profile distributes clamping pressure evenly, preventing surface damage in electrical components, machinery assemblies, and precision equipment. These fully threaded screws maintain consistent engagement depth, making them ideal for vibration-prone environments where high tensile strength (100,000 psi) prevents joint failure. Their compliance with ASME B18.6.3 standards guarantees dimensional accuracy and interchangeability across industrial fastening systems.

Specification Summary & Compliance

This 1/4"-20 x 1-1/2" slotted rounded head screw features precise Class 2A thread fit with UNC coarse threading (20 TPI) and full threading along the 1-1/2" length. Manufacturing specifications strictly adhere to ASME B18.6.3 standards for dimensional consistency and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability for global industrial applications.
