S-91783A265 10-24 x 5" ASME B18.6.3 Stainless Steel Round Head Slotted Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction and passivated finish for extended service life in harsh environments
• High tensile strength of 100,000 psi ensures reliable fastening performance under demanding industrial loads
• Precision thread fit (Class 2A) provides consistent engagement and reduces cross-threading risks during installation
• Partially threaded design with 1½" minimum thread length offers optimal grip range while minimizing material contact
• Coarse UNC threading enables faster installation and better performance in softer materials or applications requiring frequent adjustments
• Rockwell B100 hardness maintains thread integrity and prevents deformation under repeated use
• Standard slotted drive accommodates common tools for straightforward installation and maintenance

Professional Applications & Engineering Value

These 10-24 UNC partially threaded rounded head screws deliver exceptional engineering value for industrial applications where corrosion resistance and mechanical strength are critical. The 18-8 stainless steel composition combined with passivated finish creates a protective oxide layer that significantly outperforms standard finishes in moist or chemical environments. The coarse thread configuration provides superior holding power in materials prone to stripping, while the partially threaded design ensures precise clamping force concentration. These features make them ideal for machinery assembly, electrical enclosures, structural frameworks, and equipment requiring right-hand thread fasteners that maintain integrity under vibration and thermal cycling. The rounded head profile distributes pressure evenly, preventing surface damage in finished applications.

Specification Summary & Compliance

Manufactured to exacting ASME B18.6.3 specifications with Class 2A thread fit tolerance for consistent dimensional accuracy. The 5" length with 1½" minimum thread length provides versatile fastening capabilities. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and workplace safety. Thread specifications include 10-24 UNC coarse thread with right-hand direction, manufactured in the inch system for compatibility with North American industrial standards.
