Electro Hardware THS1097M07F16 Thumb Screw 10-32

Product Description

The ELECTRO HARDWARE THS1097M07F16 is a 303 stainless steel thumb screw designed for hand-tightening applications where tools are not practical or desirable. It features a knurled head for grip and a shouldered shank that provides a precise bearing surface against mating hardware. The thread is 10-32 UNC with an overall length of 0.8125 inches. Head diameter is 0.4375 inches and head height is 0.1875 inches. The shoulder diameter measures 0.375 inches with a shoulder length of 0.125 inches. The uncoated 303 stainless steel construction resists corrosion in moderate service environments, making it a practical choice for panel fastening, equipment enclosures, and instrumentation assemblies.

This thumb screw is suited for light industrial, HVAC equipment panels, electrical enclosures, and general trade applications where frequent hand removal and reinstallation is required. The knurled head allows secure finger torque without tools, reducing service time during routine maintenance or inspection. The shouldered design positions the fastener positively in clearance holes, which is useful in thin sheet metal and panel assemblies common in HVAC and electrical equipment manufacturing and field service.

Key Features

• 303 stainless steel construction for corrosion resistance in moderate service environments
• 10-32 UNC thread for compatibility with standard tapped holes in panel and enclosure hardware
• Knurled head enables firm hand grip without tools
• Shouldered shank provides a positive bearing surface and precise hole location
• Uncoated finish suitable for applications where coating buildup on threads is a concern
• Meets multiple material and finish standards including ASTM B633 and QQ-S-763

Compatibility

Designed as a standard 10-32 UNC thumb screw for use in panel assemblies, equipment enclosures, and instrumentation hardware that accept knurled-head fasteners with a shouldered shank.

Installation Notes

This fastener is installed by hand in pre-tapped 10-32 UNC holes. Verify the mating thread is clean and free of debris before installation. Do not use a wrench or driver on the knurled head, as this can deform the head or over-torque the thread. In electrical enclosures, confirm power is de-energized before opening panels or replacing fasteners.
