S-97008A825 3/8"-16 x 2" Thumb Screws

Key Features & Benefits at a Glance

• Tool-free installation and removal with ergonomic spade head design for quick manual adjustments in tight spaces
• Superior corrosion resistance through zinc-plated steel construction, extending service life in demanding environments
• High load-bearing capacity with 40,000 psi tensile strength and Rockwell B55 hardness for heavy-duty applications
• Secure fastening performance with Class 2A thread fit ensuring consistent engagement and vibration resistance
• Enhanced stability and distribution from integrated flange design, preventing over-tightening and surface damage
• Optimized for rapid assembly using UNC coarse threading that resists cross-threading and accelerates installation
• Regulatory compliance assurance meeting RoHS 3 standards for safe use across industrial sectors

Professional Applications & Engineering Value

This zinc-plated steel thumb screw delivers exceptional engineering value through its flanged spade head design and fully threaded UNC coarse spacing. The combination of Rockwell B55 hardness and 40,000 psi tensile strength addresses common industrial challenges where vibration resistance and repeated adjustments are required. The right-hand thread direction with Class 2A thread fit ensures precise engagement in machinery guards, electrical enclosures, and access panels, while the zinc plating provides essential corrosion protection in manufacturing environments. The 2" length and flange diameter of 0.688" offer optimal clamping force distribution, making it ideal for applications requiring frequent maintenance access without compromising structural integrity.
