Professional Applications & Engineering Value
This 8-32 UNC Class 3A set screw delivers exceptional engineering value in demanding industrial applications where vibration resistance and permanent positioning are critical. The 18-8 stainless steel construction provides excellent corrosion resistance for machinery exposed to moisture, chemicals, or outdoor elements. The extended tip design creates deeper penetration and superior grip on shafts, collars, and pulleys, preventing slippage in high-torque applications. With its hex headless configuration and 5/64" drive size, this fastener enables flush mounting in confined spaces while maintaining high clamping force. The coarse thread spacing ensures rapid installation and reliable performance in materials where fine threads might strip or fail, making it ideal for production lines requiring both speed and durability.
Specification Summary & Compliance
This precision set screw features 8-32 UNC Class 3A threads with right-hand direction and coarse spacing, ensuring tight tolerances for secure fastening. Critical dimensions include 3/8" length with extended tip measuring 0.086" tip length and 0.109" tip diameter, manufactured to precise tolerances for consistent performance. The fastener meets ASME B18.3 specifications for dimensional accuracy and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications requiring certified components.
