• High tensile strength of 70,000 psi provides exceptional load-bearing capacity for demanding mechanical applications
• Precision Class 2A thread fit guarantees consistent engagement and vibration resistance in assembled components
• Full threading design enables maximum grip length and uniform stress distribution across the entire fastener
• Rockwell B70 hardness rating maintains structural integrity under repeated installation and removal cycles
• Phillips No. 2 drive system offers familiar, secure tool engagement for efficient assembly operations
• Comprehensive regulatory compliance including RoHS 3 and REACH ensures environmental responsibility and global market acceptance

Professional Applications & Engineering Value

These 10-32 UNF fully threaded pan head screws deliver critical performance advantages in industrial settings where corrosion resistance and mechanical reliability are paramount. The passivated 18-8 stainless steel construction provides exceptional protection against chemical exposure and atmospheric corrosion, making them ideal for machinery, electrical enclosures, and outdoor equipment. The fine UNF thread pattern combined with Class 2A tolerance ensures precise fitment in tapped holes, reducing the risk of cross-threading during high-volume assembly operations. The rounded pan head profile with Phillips drive facilitates quick installation while maintaining a low-profile appearance, and the 1-1/4" length provides sufficient engagement for medium-thickness materials. These characteristics make these industrial fasteners particularly valuable in applications requiring repeated maintenance access without compromising fastener integrity.

Specification Summary & Compliance

Manufactured to exacting ASME B18.6.3 standards, these screws feature precision Class 2A thread fit with 10-32 UNF fine threads and right-hand orientation. The fully threaded design maintains consistent diameter of 0.19" throughout the 1-1/4" length. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility, while the Rockwell B70 hardness and 70,000 psi tensile strength verify mechanical performance meets industrial requirements for rounded head screws in critical applications.
