S-90179A251 10-24 x 1 1/2" Thumb Screws

Key Features & Benefits at a Glance

• Enhanced manual operation with spade-shaped thumb head for tool-free tightening and loosening in tight spaces
• Superior load distribution thanks to integrated flange design that increases surface contact and prevents pull-through
• Exceptional durability with Rockwell B55 hardened steel construction resisting wear in demanding industrial environments
• High tensile reliability with 40,000 psi strength rating ensuring secure fastening under mechanical stress
• Quick installation through coarse UNC threading and Class 2A fit providing smooth engagement with standard nuts
• Full-threaded versatility allowing installation at any point along the 1-1/2" length for adjustable positioning
• Environmental compliance meeting RoHS 3 standards for safe use in regulated industries

Professional Applications & Engineering Value

This 10-24 UNC spade thumb screw solves critical access challenges in industrial maintenance and equipment assembly. The steel construction with Rockwell B55 hardness provides lasting resistance to deformation during repeated manual adjustments. Engineers specify this flanged thumb screw for panels, access doors, and machinery guards where tool-less access is essential. The right-hand coarse threading ensures rapid engagement while the fully threaded design maintains consistent clamping force across the entire 1-1/2" length. Particularly valuable in electronics, automotive, and manufacturing applications where frequent component access combines with vibration resistance requirements.

Specification Summary & Compliance

Manufactured to precise Class 2A thread fit standards with UNC coarse threading (10-24 size, 0.19" diameter). Complies with RoHS 3 (2015/863/EU) environmental regulations. Features consistent 1-1/2" length with 0.344" flange diameter for reliable performance in industrial fastening applications.
