S-90920A151 6-32 x 3/4" ASME B18.6.3 Alloy Steel Torx Flat Head Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Superior torque transmission and reduced cam-out through T10 Torx drive design, ensuring reliable fastening and tool longevity
• High tensile strength of 60,000 PSI provides exceptional load-bearing capacity for heavy-duty applications
• Precision UNC coarse threading with Class 2A fit enables quick installation and secure holding in various materials
• 82° countersink angle and flat head profile creates flush surface finishes while distributing clamp load effectively
• Full threading along the 3/4" length offers maximum grip range and adjustment flexibility in assembly setups
• Compliance with ASME B18.6.3, RoHS 3, and REACH ensures standardized quality and environmental responsibility

Professional Applications & Engineering Value

These zinc-plated steel flat head screws deliver critical performance advantages in industrial machinery, electronic enclosures, and automotive assemblies where vibration resistance and corrosion protection are paramount. The T10 Torx drive system eliminates stripping issues common with Phillips drives, while the UNC coarse threads provide rapid installation in sheet metal, plastics, and pre-tapped holes. The 82° countersink seamlessly integrates with standard chamfered holes, preventing component interference in space-constrained designs. Engineered to maintain integrity under dynamic loads, these fully threaded screws with 60,000 PSI tensile strength solve common failure points in high-stress applications while meeting rigorous industry standards.

Specification Summary & Compliance

Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerances ensuring consistent mating with corresponding nuts and tapped holes. The 6-32 UNC coarse thread maintains standardized spacing (32 threads per inch) while the flat head design incorporates an 82° countersink angle per industry norms. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety and restricted substance adherence for global industrial applications.
