S-92311A304 10-24 x 1 3/4" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh industrial environments
• Maximum holding power achieved through Class 3A thread fit precision, ensuring secure fastening in critical applications
• Easy installation and removal with hex drive design that provides excellent torque transmission and prevents tool slippage
• Space-saving headless design allows for flush mounting where clearance is limited or rotating parts are involved
• Enhanced grip and anti-loosening from the cup tip configuration that bites into shaft materials effectively
• Consistent mechanical properties with Rockwell B80 hardness providing optimal strength without brittleness
• Reliable coarse threading (UNC) that resists vibration loosening and allows for quick assembly in production environments

Professional Applications & Engineering Value

This 10-24 UNC set screw delivers exceptional engineering value in applications requiring precise component positioning and rotational force transmission. The 18-8 stainless steel composition provides excellent corrosion resistance for machinery exposed to moisture, chemicals, or outdoor elements, while the Rockwell B80 hardness ensures the screw maintains its structural integrity under repeated stress. The headless design with hex drive solves space constraint challenges in assemblies where protruding fasteners would interfere with moving parts or require additional clearance. The Class 3A thread fit guarantees tight tolerances that prevent backlash in precision equipment, making these set screws ideal for securing gears, pulleys, collars, and other power transmission components in manufacturing, automotive, and industrial machinery applications where vibration resistance and positional accuracy are critical.

Specification Summary & Compliance

This 1-3/4" set screw features precise 10-24 UNC coarse threads with Class 3A thread fit for superior dimensional accuracy and engagement. Manufacturing complies with ASME B18.3 specifications ensuring consistent quality and performance. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety standards for industrial use. The right-hand thread direction and cup tip configuration provide reliable fastening solutions for demanding applications.
