S-90179A838 10-32 x 2" Thumb Screws

Key Features & Benefits at a Glance

• Enhanced manual torque application with spade head design for secure grip without tools in frequent adjustment scenarios
• Superior load distribution and seating stability due to integrated flange that prevents over-embedding into surfaces
• Reliable fine-thread engagement with 10-32 UNF Class 2A threads ensuring vibration resistance and precise fastening in machinery
• High-strength performance under stress from 40,000 psi tensile strength and Rockwell B55 hardness for durable industrial use
• Full-length threading versatility allowing consistent grip along the entire 2" length for variable material thicknesses
• Smooth right-hand thread operation enabling standard installation and removal with intuitive clockwise tightening
• Environmental regulation compliance meeting RoHS 3 standards for safe use in electronics and regulated industries

Professional Applications & Engineering Value

This 10-32 UNF thumb screw is engineered to address common industrial challenges where tool-free access and repeated adjustments are critical. The steel construction with Rockwell B55 hardness ensures resistance to wear and deformation in high-usage environments like assembly jigs, access panels, and prototyping equipment. The flanged spade head design eliminates the need for washers by providing a broad bearing surface, reducing component count and installation time. With fine threading and Class 2A fit, it maintains clamp load integrity in vibrating systems, while the fully threaded 2" length accommodates varying material depths in enclosures or machinery frames. Ideal for industrial maintenance, electronics, and OEM applications, this screw combines ergonomic handling with mechanical reliability.

Specification Summary & Compliance

Manufactured to inch system standards with a thread size of 10-32 UNF and Class 2A thread fit for consistent interchangeability. Features a 0.19" thread diameter, right-hand direction, and fully threaded 2" length. Complies with RoHS 3 (2015/863/EU) regulations, ensuring absence of hazardous substances for global industrial use.
