Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction and passivated finish, ideal for harsh industrial environments
- Precise Class 3A thread fit ensures reliable, vibration-resistant connections in critical assemblies
- High tensile strength of 70,000 psi provides exceptional load-bearing capacity for demanding applications
- Hex drive design with 1/8" drive size allows for secure tool engagement and easy installation in confined spaces
- Fully threaded 1-5/8" length offers maximum grip and adjustment flexibility across material thicknesses
- Rounded button head profile reduces surface damage and provides a finished appearance while minimizing snagging
- Rockwell B55 hardness maintains thread integrity and prevents stripping during repeated installations
Professional Applications & Engineering Value
This 10-32 UNF Class 3A Rounded Head Screw delivers exceptional engineering value in precision assemblies where vibration resistance and corrosion protection are critical. The 18-8 stainless steel material combined with passivated finish provides superior defense against chemical exposure and moisture, making it ideal for industrial equipment, electronic enclosures, and marine components. The fine UNF threading and Class 3A fit ensure zero backlash in high-vibration environments, while the hex drive design prevents cam-out during torque application. With full threading along its 1-5/8" length, it accommodates varying material thicknesses while maintaining consistent clamping force across automotive, aerospace, and machinery applications where reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit for precision UNF fine threading. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards. Features include: 10-32 UNF thread size, 0.19" thread diameter, right-hand thread direction, 0.361" head diameter, and Rockwell B55 hardness rating.
