Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in harsh industrial environments
- Exceptional tensile strength rated at 60,000 psi for reliable performance under heavy loads and vibration
- Precision Class 2A thread fit ensures smooth installation and secure fastening in UNF fine-thread applications
- Optimized drive engagement with one-way drive style prevents tampering while maintaining installation efficiency
- Full threading along 1" length provides maximum grip and load distribution across the entire fastener
- Consistent hardness control at Rockwell B70 maintains dimensional stability under mechanical stress
- Rounded head design offers reduced surface protrusion while maintaining sufficient bearing surface
Professional Applications & Engineering Value
These 10-32 UNF zinc-plated steel rounded head screws deliver critical performance advantages in precision assembly applications where fine thread engagement and corrosion protection are paramount. The combination of 60,000 psi tensile strength and Rockwell B70 hardness ensures reliable fastening in vibrating environments common to industrial machinery, electronic enclosures, and automotive components. The fully threaded design maximizes thread contact area, distributing clamp load more evenly while the zinc plating provides essential galvanic protection against oxidation in humid or chemical-exposed environments. Engineered to meet ASME B18.6.3 specifications, these screws maintain dimensional consistency for repeatable assembly processes across production runs.
Specification Summary & Compliance
Manufactured to Class 2A thread fit tolerance with UNF fine threads (10-32) in right-hand direction. Compliant with ASME B18.6.3 dimensional standards, RoHS 3 (2015/863/EU) for hazardous substance restrictions, and REACH (EC 1907/2006) regulations for chemical safety. The inch-system screws feature standardized rounded head profile with 0.359" diameter and 0.137" height, ensuring compatibility with standard tooling and installation procedures.
