Key Features & Benefits at a Glance
- Superior torque transmission with Torx Plus drive (IP10/T10) for reduced cam-out and enhanced installation efficiency in high-torque applications.
- Exceptional corrosion resistance due to zinc-plated alloy steel construction, ensuring long-term durability in harsh industrial environments.
- High tensile strength of 120,000 psi and Rockwell C39 hardness for reliable performance under heavy loads and vibration.
- Precise Class 3A thread fit with UNC coarse spacing for secure fastening and reduced risk of cross-threading in assembly operations.
- Fully threaded 1-1/2" length provides maximum grip and holding power across the entire fastener for consistent clamping force.
- Rounded button head design offers a low-profile, aesthetically clean finish while minimizing snagging in confined spaces.
- Compliance with industry standards including ASME B18.3 and ASTM F835, ensuring interchangeability and quality assurance.
Professional Applications & Engineering Value
These 6-32 UNC Torx Plus zinc-plated alloy steel screws deliver critical engineering solutions where vibration resistance, corrosion protection, and high-strength fastening are paramount. The Torx Plus drive system eliminates tool slippage during high-torque assembly, reducing operator fatigue and preventing damage to drive features in automated production lines. With Class 3A thread fit and coarse threading, they provide rapid installation in sheet metal, machinery, and electronic enclosures while maintaining precise alignment. The zinc-plated surface treatment combats oxidation in humid or outdoor settings, extending service life in automotive, aerospace, and industrial equipment applications where reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to exacting Class 3A thread tolerances with UNC coarse thread spacing and right-hand threading. Complies with ASME B18.3 dimensional specifications and ASTM F835 material standards. Meets environmental regulations including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance for hazardous substance restrictions.
