• Full-length threading providing maximum grip and adjustment flexibility across the entire 3/4" length

Professional Applications & Engineering Value

This zinc-plated steel thumb screw delivers exceptional value in industrial settings where frequent access and adjustment are required. The 8-32 UNC coarse thread configuration enables rapid installation while minimizing cross-threading incidents, significantly reducing assembly time in production environments. The spade head design allows operators to apply substantial torque without tools, making it ideal for equipment panels, electrical enclosures, and machinery guards that require regular maintenance. With 40,000 PSI tensile strength and Rockwell B55 hardness, these thumb screws maintain clamping force in high-vibration applications while the zinc plating provides essential corrosion protection in demanding industrial conditions. The fully threaded 3/4" length ensures maximum engagement depth for secure fastening across various material thicknesses.

Specification Summary & Compliance
