Professional Applications & Engineering Value

This 10-24 UNC thumb screw delivers critical advantages in applications requiring frequent adjustments or tool-free access. The steel construction with Rockwell B55 hardness ensures lasting performance in high-cycle environments, while the coarse thread pattern provides rapid installation in soft materials or blind holes. The flanged spade head design solves common grip and marring issues, distributing pressure evenly across surfaces. Ideal for industrial equipment panels, electronic enclosures, and machinery guards, this fully threaded right-hand screw maintains consistent clamping force with its 0.344" flange diameter, eliminating the need for separate washers and reducing assembly time.

Specification Summary & Compliance
