S-93015A211 10-24 x 1 1/4" Thumb Screws

Key Features & Benefits at a Glance

• Enhanced manual grip with 3/4" knurled head texture for secure, tool-free tightening and loosening in high-vibration environments
• Superior corrosion resistance from 18-8 stainless steel construction, ensuring long-term reliability in humid or chemical-exposed settings
• Space-saving low-profile design with minimal head height for applications with restricted clearance requirements
• High mechanical strength with 80,000 psi tensile strength and Rockwell B83 hardness for demanding industrial applications
• Quick installation with 10-24 UNC coarse threading that resists cross-threading and accelerates assembly processes
• Precise thread engagement through Class 2A thread fit and extended tip for accurate alignment and reduced component damage
• Environmental compliance meeting RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

This 18-8 stainless steel thumb screw delivers exceptional value in industrial applications where frequent adjustments and reliable fastening are critical. The knurled head provides superior manual grip even with oily hands or gloves, eliminating the need for tools in maintenance-heavy environments like machinery guards, electronic enclosures, and production jigs. The low-profile round head design minimizes protrusion in confined spaces while the 10-24 UNC coarse threads ensure rapid installation and removal. With partial threading and extended tip, alignment is simplified during assembly, reducing the risk of cross-threading damage to expensive components. The combination of 80,000 psi tensile strength and corrosion-resistant stainless steel makes this thumb screw ideal for applications requiring both mechanical durability and environmental resistance.
